How to properly use polyethylene glue at home and an overview of the best types

The choice of adhesive for polyethylene is a rather responsible process. To achieve this, it is worth familiarizing yourself with the key criteria. Properly selected substance allows to fix different types of polyethylene, providing strong adhesion. In order to securely fix the material, the technology of the procedure should be strictly observed. It includes a series of step-by-step actions.

Composition and distinctive properties of polyethylene

Polyethylene is used for packaging, as an insulating layer. Electrical insulation is made of it. The film provides reliable protection against moisture and promotes the absorption of neurons, which are a type of radioactive radiation. The foam material is used to heat the parts.

There is no need to glue polyethylene or cellophane with conventional compounds. This is due to the chemical inertness of the material. Therefore, it is worth using a special adhesive. The fixing of the material is carried out on a chemical or electrical basis.

It is important that the substance firmly adheres to the surface of the film. After hardening, it should firmly fix the elements to each other.

How to weld polyethylene products

To weld polyethylene objects, it is worth considering the type of material from which they are made.

Sparkling

Such polyethylene has a porous structure. Therefore, it provides insulation against heat, water and vapors. Due to its low cost and ease of use, it is often used in construction. It is recommended to use a two-part adhesive to bond the foam tape. It must be methyl acrylate based. This composition is characterized by high adhesion. It can be used for polyethylene or polyvinyl chloride.

To achieve a strong and secure grip, the surface must be sanded. Physical impact is also permitted - in particular, fire. Sometimes chemical treatment is used. For this, a fluorination technique is used.

Tight

The most convenient tool for welding greenhouse elements is a roller. It must have an integrated electric heater. The tool is suitable when you need to do a large amount of work. Usually these devices are made on their own. If this is not possible, household appliances that can be heated to 250 degrees are used.

Reinforced

Reinforced films are often used for greenhouses. In this case, it is important to ensure the most reliable fixation. Such a structure should serve for a long time and provide reliable protection from climatic factors. In this case, any type of welding will be the best solution.

Cellophane

It is better to use a special glue to hold the cellophane fragments together.When choosing, it is recommended to pay attention to the composition and quality.

Review of Effective Grades and Varieties for Polyethylene Bonding

There are many types of effective and reliable adhesives on the market today. Each of them has certain characteristics.

BF-2

This tool can be used to fix plastics, metal objects, ceramics. This glue is often used in restorations. The composition is prohibited to use for dishes. This is due to the presence of toxic components in the composition - phenol and aldehydes. Glue is considered universal. It is chemically inert and moisture resistant.

BF-4

In terms of chemical resistance, the agent coincides with BF-2. However, the scope of the composition is different. BF-4 is used to fix elastic materials subject to wrinkles and vibrations. These include leather, textolite, alloys. Also, the substance helps to bond wood, metals.

Bi-component

This glue is characterized by high strength. The composition is considered very durable. It has a transparent texture and does not harden too quickly. It takes 4 minutes. Thanks to this, you can take your time when working. The composition reliably fixes metal objects. It can also be used to glue plexiglass.

Epoxy

This substance is made on the basis of a hardener and a polyepoxy resin. It is used to repair fiberglass items. Using epoxy glue, you can fix wood, porcelain, glass, metal. It is also used for different alloys.

The substance is used to fill cracks and voids. It helps to restore shape and volume to objects.The seam is characterized by resistance to oil, water, gasoline.

Application of filled acrylate glue

This agent is suitable for low adhesion materials. Liquids have difficulty adhering to polyethylene. As a result, they are expelled from the contact area of the surfaces. Microscopic glass beads are present in the glue. They prevent the substance from escaping from the bonding area and form a gap of the required size. Therefore, it is possible to obtain the desired bonding surface. Once solidified, it is possible to obtain a solid fixation.

To glue the film, the surfaces must be thoroughly degreased and well dried. The glue should be supplied by an exclusive mixer. The optimal temperature regime is + 21-23 degrees. The substance remains in a liquid state for no more than 2-3 minutes. After applying the composition, the parts are immediately joined.

It will take a few hours to achieve full seam preparation and high strength. It is worth keeping the glue joint at a temperature of + 15-70 degrees.

How to glue with epoxy glue

To bond polyethylene well, its surface must be properly prepared. To do this, it must be degreased and dried. Both elements are recommended to be treated with special solutions. To do this, it is permissible to use chromic anhydride at a concentration of 15-20%. You can also use 20-30% potassium dichromate. These substances have a caustic consistency and are classified as dangerous carcinogens.

It is also allowed to take another strong oxidizing agent. A strong solution of potassium permanganate can help.Its effectiveness is practically not inferior, but it is considered safer. After surface treatment, it is recommended to dry it again. Then it is worth preparing the epoxy adhesive. To do this, it is recommended to use the instructions. Cover the two fragments with a thin layer of glue and put them together. Keep for several hours. This should be done at a temperature of + 30-45 degrees. However, it is best to leave the product for a day.

Using the universal roller

The most convenient device for fixing polyethylene is considered a universal roller. It must include an electric heater. Quite often these videos are made by hand. However, for this you need to have the appropriate qualifications. An alternative would be any device that can be heated to 250 degrees.

Alternative methods

To fix the polyethylene, you can use other devices.

Iron

It is possible to connect the polyethylene sheets with the sole of the iron. During the heating process, the material acquires a liquid consistency and combines at the molecular level. As a result, it is possible to achieve a strong fixation. To fix the film with an iron, it is recommended to proceed as follows:

Find the right temperature. It's worth doing it through a hands-on trial.
Place the sheets on top of each other. To prevent the film from sticking to the iron, place a sheet of paper on it.
Go over the sheet with an iron. As a result, the film should start merging.

It is important to ensure that the paper does not stick to the surface of the iron. If this happens, just moisten the sheet with a damp cloth and remove it after a few minutes.

To assess the reliability of fixation, the film should be pulled in different directions. It is important to ensure that the seam does not tear.

Soldering iron

To use a household soldering iron, you need to use a special nozzle. Otherwise, the joint will have an uneven structure. To make your work more comfortable, the accessory should move like a roller. In addition, it is allowed to replace the sting with an aluminum bar. Its contact surface must be 2 millimeters. It is allowed to weld with a copper bar of the same section.

To weld polyethylene, you must do the following:

attach the tip to the device with a screw;
degrease the surface to be joined;
combine the leaves;
run a hot soldering iron over the joint area;
if it is necessary to fix a large area, a metal plate is used as a sting - it should be copper or aluminum.

open flame

An open source of flame can be a gas burner or regular matches. You can also take a torch or a candle. By moving the fire source along the joint, it will be possible to achieve a strong fixation of the film.

To do this, you must do the following:

degrease the polymer sheets;
fix the material with bars;
the welding zone must protrude 3 to 5 millimeters beyond the edge;
pull the flame source onto the protruding area;
the film will melt and weld together;
as a result, a seam will form, which looks like a dense roll.

How to glue polythene to metal

For this purpose, you can use products based on ethyl 2-cyanoacrylate. These types of adhesives provide high strength bonds. Using super glue will also help achieve the desired effect.

Additional tips and tricks

To achieve reliable fixation of polyethylene, these recommendations should be followed:

If the seam is to be very durable, then welding is considered the best fastening option. It is important to avoid sudden cooling of the joint.
It is not necessary to mechanically prepare the surface before using filled acrylic adhesive. The only work required is degreasing and cleaning.
After gluing the fragments, the seam should be left for 4-5 hours. The temperature should be between + 15 and 70 degrees.

For fixing polyethylene, it is allowed to use different types of glue. This allows you to choose the optimal composition according to your tasks. In this case, it is important to respect the rules of procedure.
