Natural rubber is manufactured from latex, and a part of the non-rubber components often contained in latex are left in the solid natural rubber. In general, natural rubber contains 92-95% vulcanized rubber hydrocarbons, and non-vulcanized rubber hydrocarbons account for 5%-8%. Because the production method is not the same, the origin is not the same or even the picking season is not the same, the proportion of this ingredient is likely to be different, but most of it will be within the scope.

The protein can push the vulcanized rubber and slow the embrittlement. On the other hand, the protein has a strong ability to absorb water, which can cause the vulcanized rubber to grow mold and reduce the dielectric strength, and the protein also has the defect of promoting the natural heat.

Toluene extracts are some advanced fatty acids and sterols, some of which act as pure natural rubber antioxidant and vulcanization accelerator, and some can help the powder compound disperse in the whole process of mixing and soften the raw rubber.

Hebei Samai Technology Co., Ltd. mainly produces sewage water blocking air bags, pipeline blocking air bags, high pressure air bags, repair air bags and disembark air bags and Marine guard strings and other rubber products.

The key ash contains magnesium phosphate and calcium carbonate and other salts, there is a small amount of copper, manganese, iron and other metal compounds, because this valence metal ions can promote the embrittlement of vulcanized rubber, so their composition should be manipulated.

The water in the dry rubber does not exceed 1%, which can be evaporated during the production process, but when the water component is too much, it will not only make the raw rubber storage process easy to grow mold, but also continue to harm the production and processing of vulcanized rubber, such as the mutual compounding agent is easy to caking when mixing rubber; The whole process of injection molding and pressing out is easy to cause steam bubbles, and the whole process of vulcanized rubber causes steam bubbles or honeycombs.
