Foam rubber and its main characteristics

The first mention of foam rubber was recorded in Germany in 1941, where it was obtained with random foaming of polyurethane foam. Figuratively speaking, foam rubber is a material with a porous structure filled with air. The scope of this material is wide enough, it is well compressible due to its elasticity, has excellent air permeability and keeps the original shape. Most often used for the manufacture of furniture, sporting goods, car seats, materials for soundproofing and soft toys. Also in everyday life has multiple applications, it produces a variety of paint rollers, sponges for washing dishes and cleaning. In Europe, this material is used as a packaging for the goods.

Use of glue

The adhesive for foam rubber is quite simple to use. For its application, it is best to purchase a special spray gun, for which you need to use a nozzle - attachments up to 1.8 mm in diameter. The prepared composition can be sprayed into one layer, and if necessary, then in two. Atmosfernoe pressure on the gun should be from three to six bars. After applying a foam on the foam surface, a small film appears.

After the composition is sprayed, it is necessary to wait for the evaporation of the solvent. The duration may depend on many factors, such as air temperature, the number of layers deposited and the speed of the wind, if this occurs on the street. The period for which it is necessary to connect two surfaces should not exceed 3 minutes, since during this interval the composition will dry completely. Docking the two parts must be done right away, since after the interaction of the prepared materials, it will be impossible to correct the error. Before applying the glue for gluing foam rubber, its temperature should be brought to +20 C, and then mix well. Such compounds are perfectly suited for spring mattresses and upholstered furniture, they are also used for combining foams with wood, cardboard and textiles. In production, this substance is called a furniture adhesive for foam rubber, as it is very often used in this industry.

Composition of the glue

For a long time, the base of the paste was styrene butadiene, polyurethane and polychloroprene. Thanks to the development of technology, it was possible to significantly reduce rubber and combustible components. To date, the new team has the smallest negative impact on those who work with it, as well as users in the future, and causes minimal harm to the environment.

Adhesive for foam rubber without a smell on a water basis is the safest in comparison with those in which there are solvents in the composition. Since it does not smell, it is comfortable to work with, it also does not emit toxins. The main advantage of this material is fire safety. The pluses can be attributed to the fact that less raw material is used for the ultimate goal.

To apply glue, you can use a brush or an aerosol spray gun. When using it, it is necessary to follow the instructions and adhere to safety regulations.

How to choose high-quality glue?

Passed the time when the composition consisted of fire-hazardous and toxic solvents, now they are more harmless. Such components are characterized by instantaneous adhesion and good elasticity of the joint. The main advantages of modern adhesives include:
- absence of fire-hazardous solvents;
- excellent spraying from the gun;
- soft and elastic joints;
- high content of dry residue.

The main characteristics of a quality product

In order that after coming to the store not be lost from the abundance of choice, you need to know which adhesive for foam rubber is considered quality:
- it is very important that it provides a strong connection;
- you need to pay attention to the fact that this composition could paste not only pieces of foam rubber to each other, but also to cloth, leather, wood, synthetic rubber, plastic and metal;
- it should not ignite;
- safe when applied, and also in the future use;
- it is also important that it is waterproof;
- in the end, will make an elastic seam.

Features of good adhesives

We can distinguish the following differences, which are used in adhesive compositions for working with foam rubber:
- the adhesive for foam rubber should not contain toluene, as well as all its analogues;
- after application, the composition should remain sticky and viscous for several minutes, as it is necessary for working with large areas;
- after opening the container, the material must be fully prepared for use, it should not be stirred and shaken.

Safety regulations

Experts say that it is best to apply a gun or buy an aerosol adhesive for foam rubber. Although no one forbids the use of a roller or brush, but this method will be accompanied by a significant expenditure of raw materials. The composition is practically odorless, but it is best to use it in rooms with good ventilation, so as not to get poisoning with toxins.

Before gluing several surfaces, you need to follow certain rules:
- initially the surface is cleaned of grease, dust and dirt;
- the adhesive for foam rubber should be applied in a thin layer and wait until the solvent vapor evaporates;
- if a one-side application occurs, the composition is covered with a more rigid surface;
- all procedures must be carried out only at room temperature. Otherwise, the glue can thicken and lose all its properties, which in the end will greatly affect the finished product.
