Insoluble sulfur exists in the rubber compound in the form of sand crystal in the rubber mixing process, to avoid the plastic spray frost, and prevent the migration of sulfur, so that the material can maintain a good shape of sticky. Insoluble sulfur instability, in the rubber vulcanization temperature as high as the jkcan be reduced to ordinary sulfur, to
It is understood that rubber release agent is generally divided into external and internal use. The traditional release agent is generally topical, that is coated on the surface of the cavity, and customary also known as the release agent, the main products are talcum powder, mica powder, soap, paraffin, polytetrafluoroethylene and silicone oil, etc. Have a certain stripping effect, but

Rubber shock block generally use natural rubber and neoprene, requiring oil-resistant using nitrile rubber, requiring high and low temperature resistant using silicone rubber, requiring high damping using butyl rubber. Rubber shock pad products manufacturing process, in addition to rubber air spring similar to the tire, the majority are similar to model products. Usually made into support or connectors, widely used
First: raw rubber system 1) Rubber and plastic is a very common means, and with high styrene, PVC / NBR alloy effect can also be hardened. 2) Change the type of plastic grades, but also can improve the hardness. Second: vulcanization promotion system 1) By increasing the curing agent to increase the cross-chain density, increase the hardness, such as increased
January 1, China Export Tire Quality Technology Promotion Committee issued export tire enterprises” on the same line with the standard homogeneous “that the criteria. The establishment of tire product “the same line with the standard homogeneous” quality and safety supervision mode, to accelerate the tire products “with the same line with the standard homogeneous” that provide system protection, the initial
