Rubber Products The More Uniform The More

Foam rubber products to rubber as the substrate, Rubber Products the use of physical foaming or chemical foaming method for production, resulting in sponge-like rubber porous structure. This technology has been widely used in the production industry, such as automotive doors and windows seal, Rubber Products cushion, construction pads, seismic materials, sports protection facilities.

The so-called foam rubber is also widely known as the rubber foam technology, is the use of specific blowing agent to deal with rubber, making the rubber with a characteristic performance of a means of treatment. This technology is widely used in the current production field and is one of the most common methods of production at this stage.

Foam rubber products is the production of the most used one of the products, according to the hole can be divided into microporous structure, porous structure of two. The microporous structure can be divided into separate foam products and continuous foam products. According to the raw material of rubber can be divided into natural rubber products, such as natural rubber foam products, Rubber Products isoprene foam products, sbr foam products, ethylene propylene rubber foam products.

Foam rubber products in the current society more and more widely used in the production and production process and thermoplastic foam has a world of difference, it exists a vulcanization rate and the decomposition rate of blowing agent to match problem. In other words, Rubber Products the success of a rubber material foam in addition to the speed of the existence of a close relationship between the rubber material vulcanization process and the decomposition of foaming agent occurs when the principle is basically the same, Rubber Products is a gas expansion wall Resulting in the corresponding resistance of the extension process.

1, plastic refining

The essence of raw rubber is to break the rubber chain of macromolecules. Improve the plasticity of the rubber, so that the mixing agent mixing and mixing processing easier. Rubber Products In the preparation of foam rubber products, the better the plasticity of rubber, Rubber Products the more easy to produce cell uniformity, density, shrinkage of small products. So raw plastic to be fully plasticized.

2, parking

  After mixing the rubber, must be placed for a long enough time, generally to be parked 2 ~ 4h, so that all kinds of additives in the compound fully dispersed, Rubber Products the more uniform dispersion of rubber additives, product size stability, surface Smoothness, the better the degree of bubble uniformity.

  3, temperature

  Rubber foam is very sensitive to temperature. The same kind of compound, Rubber Products different foaming effect at different temperatures. Because of the degree of sensitivity of the foaming system and the vulcanization system to temperature, Rubber Products the vulcanization temperature is changed to re-adjust the vulcanization system to match the foaming system.

  4, forming

  Foam rubber products, molding methods are: extrusion molding, molding, plate molding and other methods. epdm foam products commonly used extrusion molding, nbr more use of molding.
