Plastic products are durable and do not require special maintenance conditions. To make them, liquid plastic is used for pouring, which is purchased in a store or made independently at home. Before starting work, you must familiarize yourself with the cooking technology and observe safety precautions.
How to make liquid plastic with your own hands? Manufacturing technology and scope of application
Plastic is a universal material. It has found wide application in the manufacture of various components and parts in both industrial and household appliances.
Products made from it are used in interior design of residential premises and offices. A type of material called liquid plastic allows you to create crafts of a wide variety of shapes and sizes. This makes it possible to implement original design solutions. How to make liquid plastic at home?
Types of adhesives
The following compounds are most often used to seal balcony and window structures.
Cosmofen 345
Cosmofen 345 is an excellent product for sealing and sealing seams between window parts. The glue does not spread, is white in color, is not afraid of moisture and does not turn yellow under the influence of ultraviolet radiation. Thanks to the specific shape - a bottle with a tip, the composition is very easy to apply
Considering that a portion freezes in 60 seconds, this is an important advantage
CosmofenPlusHV
CosmofenPlusHV is a version of “liquid nails”. Its main task is to fasten parts: strips, drains, window sills and other things. However, Plus also has the properties of sealant. The composition has increased viscosity
This is an important advantage, since such a seam has some elasticity and compensates for the difference in the thermal conductivity of different materials. The glue is produced in sealed packages of 200 g.
The photo shows the PlusHV composition, packaged in 200 g. CosmofenСа 12 is a universal option, suitable for gluing not only window parts, but also other products made of PVC, polypropylene, wood, metal, glass. The strength of the connection is in no way inferior to fastening with nails and screws.
The disadvantage of CA 12 is the small volume of packaging. For household needs, a bottle of 20 and 50 g is enough, but for gluing such large parts as platband or window sill, you have to use several packages of CA 12.
Materials for production
To make liquid plastic with your own hands, you need to prepare the following:
In this case, the amount of acetone used depends on the desired volume of the finished product.
If you want to make liquid plastic with your own hands, the recipe for its preparation will be based on dissolving polystyrene foam in acetone. For this, polystyrene foam is used. It is a packaging container for various household and electronic equipment.
How to make liquid plastic with your own hands
The step-by-step recipe for preparing the named material looks like this:
Knowing how to make liquid plastic, remember that complete hardening of the mass lasts 20-30 hours. Consequently, the part being manufactured cannot be removed from the mold within this period of time.
The substance should be applied with a small rubber spatula. Movements should be smooth. Liquid plastic must be stretched over the surface to be treated. If you use it to fill cracks, it is better to use brushes with hard bristles. They need to “push” the mixture into the gaps. After the plastic has hardened, it is recommended to apply another layer of the substance.
The described product has long been sold in finished form. It only needs to be heated in a water bath or in special equipment. A hair dryer is also often used for this.
As a rule, liquid plastic is produced in dense packaging. Its terms and storage conditions are strict. The temperature in the room where it is located should not fall below 15 degrees. Otherwise, the product will lose its performance characteristics:
The cost of liquid plastic is quite high. That's why it's better to do it yourself.
By soldering
Soldering plastic involves heating: the parts melt, connect (“merge” with each other) and after solidification remain indestructible. However, only thermoplastic can be soldered. This is a polymer that does not lose its properties after heating and hardening.
Thermoplastic is divided into several types:
- Solders well: polypropylene, polyethylene, PVC (polyvinyl chloride);
- Poor soldering: polystyrene, polyvinyl chloride.
Before starting work, the part is removed (if possible), cleaned of dirt and degreased.
We use a hair dryer
To work, you need a special construction hair dryer, which heats up to a temperature of 300 degrees. You will also need a plastic rod: when melted, it will glue the parts together.

Figuring out how to solder plastic is not difficult. The process proceeds as follows:
- The hair dryer is removed from the stand and the temperature is set. During the work, you need to monitor it: if the plastic does not melt well, increase the temperature, if too much, decrease it.
- The rod and damaged parts (or crack) begin to heat up. They become soft and begin to gradually stick together. You need to focus on the surface being repaired: if it swells, then the process is going correctly.
It is important to completely warm up the damaged part until it is soft. If it remains too hard, the rod will not secure and the connection will be weak.
We use a soldering iron and mesh
Not everyone has a hair dryer, but a soldering iron is more versatile. In addition, this method allows you to obtain a strong and high-quality connection that is not afraid of external influences. For example, it is used to repair a bumper.
To work, you need a flat nozzle, which will need to press the mesh, and the mesh itself. It is better to use copper or brass with small cells. The size depends on the area of work.

The process of soldering plastic with a soldering iron consists of several steps:
- The temperature of the soldering iron depends on its power. For example, for a low-power tool, the maximum temperature is set at 45 W so that the plastic melts faster.
- The damaged part is firmly fixed so that the parts do not separate. To do this, you need to melt the junction in several places and fasten them to each other.
- The mesh is placed on top of the crack, a soldering iron is brought in and they begin to “sink” the mesh into the molten plastic. The mesh should completely “go” inside, the parts will be held on it.
- When the plastic has cooled, you need to check the strength of the connection.
Since the surface of the part is not very beautiful and can “walk,” it is additionally reinforced with a rod of a suitable color. The latter is melted, applied in place and the excess is removed, then painted.

Applications of liquid plastic in finishing
The product has been used for finishing for a long time. After its application, an elastic film appears on the treated surface. It is highly waterproof and UV resistant. The material protected by such a film is not afraid of exposure to aggressive detergents. The smooth surface has a pleasant shine and retains its characteristics for many years.

How to make liquid plastic with your own hands
There are several ways to make liquid plastic at home. Each method will require its own materials.
You should not forget about the precautions:
Necessary materials
For the first method of preparing liquid plastic with your own hands, you will need the following materials:
For the second method:
Contact heating method
Technologically, this is the simplest method of welding plastic. It doesn't even require electrodes. But the design of the apparatus used is different for welding sheet materials or, for example, for connecting pipes.
The simplest apparatus used for welding small parts is a regular 220 V electric soldering iron. To increase the heating area, and also to avoid damaging the tip, a special nozzle can be used.
It can weld the most common plastics - polyethylene and polypropylene. Most household plastic parts are made from them.
The principle of this method is simple. The edges of the parts are heated (for polyethylene and polypropylene the temperature should be 200-260 °C), overlapped or butt-to-butt and pressed tightly in a clamp or vice.
Cooling must occur under pressure, otherwise it will not be possible to achieve a high-quality seam. Before starting work, it is recommended to clean and rinse the edges .
A special welding machine is used for welding sheet plastic in large volumes. Connecting pipes by heating also requires a special tool. Welding machines for pipes are divided into 2 types - for butt welding and for socket welding.
The second method is intended for welding pipes of different diameters that fit tightly into one another. Such devices provide the necessary pressure.
Manufacturing technology
The first method is based on melting polystyrene foam in acetone. For this:
Polystyrene foam should not be purchased specially; it will fit from the packaging included with the equipment.
Do not dispose of leftover acetone through the toilet or other drainpipes. He is capable of damaging them. If your hand comes into contact with unhardened material, you should immediately wash your hands with running water and soapy water.
Step-by-step manufacturing technology using the second method:
To fill small forms, do not overheat the plastic.
The material used can be a regular plastic box marked PP.
We recommend watching the video instructions:
Scope of application
Liquid plastic, which was produced using the first method, is used for surface treatment. A film is formed on it that has water-repellent properties and resistance to solar radiation. The coating acquires shine, resists the influence of chemicals, and is durable. When treating a metal surface, the film protects against rust formation. No primer treatment is required before application.
This type is also used for filling gaps when installing plastic panels. The elements are processed by the substance. After drying, a protective film is obtained.
The substance hardens for about half an hour, an hour. When pouring it into molds, they should not be moved or rocked until completely hardened.
Car owners also use liquid mass for non-abrasive treatment. It meets all the requirements of modern motorists.
In the second manufacturing method, the mass is used for pouring into molds.
Liquid plastic with your own hands, quickly and easily
I decided to make some plastic to make a handle for a file, the idea is not new, but it works
Hello dear readers
It often happens that you need to make some object from plastic, for example, a handle for a homemade knife or for a file, a screwdriver, in general, for anything. Where can you get plastic from which you can mold the desired shape like plasticine? But I found an excellent recipe for how to easily and quickly make this type of plastic without heating. I hasten to share this idea with you, maybe someone will find it useful. Almost everyone has everything they need at home or in the barn.

DIY liquid plastic, my realized idea from plastic waste by Peling
So, difficult but exciting times have come, new advancements of the forgotten in a new quality. Namely, today we will talk about homemade liquid plastic. It is based on the old method of making Dichloroethane. For those who don't know what this is, the description is below.
Dichloroethane is an adhesive for welding plexiglass. The method of its manufacture is to dissolve camera film in liquid acetone, which is no longer available anywhere these days. But in addition to film, different types of ABS plastics can be dissolved in acetone. In the future I will tell you how to find a more suitable plastic to melt in acetone.
Well, in this topic, I didn’t bother too much with plastic and took regular ABS plastic, crushed 50 meters of plastic into a 200 ml jar, and filled them with acetone. After an hour, the resulting mixture can rightfully be called liquid plastic and, depending on the concentration of plastic in relation to acetone, you can find many applications for this mixture. And if we take into account the fact that it is not necessary to buy ABS plastic, but you can find something unnecessary that can be thrown away or put to good use. I think this method will be used by many car, radio, and so on enthusiasts.
During the tests and experiments that I carried out over the course of a year with plastics, I came to the conclusion that this method can not only strengthen structures, protect them from external factors, make them stronger, insulate, and do much more. So this is still the cheapest and highest quality coating, which can have a lot of uses, and can be not only a thin layer, but even a monolithic slab, depending on your plastic reserves and finances for the purchase of Acetone.
Two approaches
Welding of plastics can be done in various ways. But there are two main approaches - temperature and cold. The first is based on exposing the plastic to a relatively high temperature (in the range of 200-300 °C for different types of plastics).
Thermal welding of plastic can be carried out:
- flow of hot gas (air, nitrogen, argon);
- hot contact tool (soldering iron, special machine for welding plastic);
- molten additive;
- friction;
- ultrasonic waves;
- spot heating with laser, infrared or other light radiation;
- high frequency electric current.
The principle of cold welding is different. It is also divided into two fundamentally different subspecies. The first is welding the plastic by partial melting using chemical solvents.
Under the influence of certain chemicals, the edges being joined soften, join under pressure, and cool under pressure. Due to the complexity, as well as the fact that the most popular polymers polyethylene and polypropylene are not amenable to this method, it is rarely used in everyday life.
The second subtype is the use of a two-component polymer composition, according to the same principle as cold welding of metal. It is not real welding, but it can provide a fairly strong connection, close to the strength of the plastic surfaces being joined.
