Rubber sponge, a material that may not be mentioned much in our daily life, but plays an important role in many industrial, civil and medical fields.

The main components of rubber and plastic sponge are rubber and plastic, in addition to sodium alginate, magnesium oxide, microporous silicon calcium and other more than 20 auxiliary materials. These materials are mixed in a certain proportion and foamed by heating. In the process of heating, the blowing agent begins to decompose to produce gas, so that a large number of pores are formed in the mixture. These pores are the main reason for the light weight and softness of rubber and plastic sponges.

After foaming, rubber and plastic sponges need to be cooled and cured. During the cooling process, the shape and structure of the rubber sponge are stabilized, ensuring that it has the required elasticity and stability. Curing treatment is to further increase the hardness and durability of the material, so that it can meet the needs of a variety of application scenarios.

The process of making rubber and plastic sponges is quite complicated. From the selection of raw materials, mixing, mixing, to extrusion, cutting, inspection, and finally packaging, each step requires strict operation and control to ensure the quality and performance of the final product.

Rubber sponge has many advantages, so that it is widely used in various fields. First of all, due to its light weight and softness, rubber and plastic sponges are very suitable for packaging materials. It can provide good cushioning and protection, protecting items from impact and damage. Secondly, rubber and plastic sponges also have the characteristics of sound insulation and shock absorption, so they are widely used in the construction and automotive industries. It can effectively reduce noise transmission and vibration, providing a more comfortable and quiet environment. In addition, rubber sponge also has waterproof, corrosion resistance and wear resistance, making it widely used in outdoor and industrial fields.

Rubber foam is mainly made of rubber and plastic closed cell foam structural materials, with thermal insulation, sound absorption, shock absorption, waterproof and moisture-proof properties and has a wide range of application prospects.
