Rubber Rings Factory Introduces The Processing Technology Of Foam Rubber Products

Rubber Rings Factory introduces the processing technology of foam rubber products:

1. The essence of mature rubber is to destroy and destroy the large molecular chain of rubber. Improve the plasticity of the rubber and make the mixing and kneading process of the ingredients easier. When preparing foam rubber products, the better the plasticity of the rubber, the easier it is to produce products with uniform cells, low density and low shrinkage. Therefore, raw rubber must be chewed completely.

2. After mixing the rubber, it must be left for a long enough time. Generally, it should be left for 2 to 4 hours so that various additives can be fully dispersed in the rubber. The more uniform the dispersion of rubber additives, the better the product dimensional stability, surface smoothness and bubble uniformity.

3. Temperature Rubber foaming is very sensitive to temperature. The same type of compound has different foaming effects at different temperatures. Because the foaming system and the vulcanizing system have different sensitivity to temperature. Changing the curing temperature requires readjustment to match the curing system with the foaming system.

4. The molding methods of foamed rubber products include: extrusion molding, compression molding, flat molding and other methods. EPDM foam products are commonly extruded. For molding, NBR mainly uses compression molding.
