In the synthesis of silicone rubber, various catalysts and the adjustment of silica and white carbon are always indispensable. The same semi-finished raw materials are indispensable for the addition of various color rubbers and vulcanizing agents during the molding and vulcanization of silicone products. Therefore, Different types of vulcanizing agents can play different roles and effects. The role of vulcanizing agent is a very important auxiliary material in silicone products. If the vulcanizing agent is used well, the product will be icing on the cake; if it is not used properly, there will be major problems! Let's explore together today.

Vulcanizing agent
The use of vulcanizing agent: in natural rubber, it can prevent vulcanization reversion, improve heat resistance, reduce heat generation, aging resistance, and improve the adhesion between rubber and cord and the modulus of vulcanized rubber. Used in truck tire shoulder rubber, buffer layer and other rubbers, it can solve the problem of shoulder emptying of biased truck tires, and can also be used in large-sized and thick natural rubber products and various rubber miscellaneous products. As a vulcanization accelerator for neoprene, it can significantly improve the scorch resistance of the compounded rubber. It is suitable for processing neoprene in high temperature seasons in the south. To improve compression deformation, calcium hydroxide and diphenylethylenediamine are combined to form a maleimide vulcanization system. The dosage is 2-4phr, which can greatly reduce the compression set and improve the temperature resistance.

Low temperature vulcanizing agent
Low-temperature vulcanizing agent: It is a high-efficiency silicone rubber vulcanization accelerator. It is used for silicone rubber moldless vulcanization and hot air extrusion of silicone rubber vulcanizing agent. The product has high cross-linking density, good transparency, light taste and good vulcanization color. It is divided into two types: transparent and ordinary; it is also used as a fast curing agent for unsaturated polyester resins. Can be used in resin bolts that cure rapidly at low temperatures.

Color gluecolor paste
Color gluecolor paste is used for: coloring silicone rubber products, mostly used in silicone gifts, silicone kitchen utensils, silicone cables and other colorful products. Compared with toner, silica gel masterbatch has the characteristics of environmental protection, high temperature resistance, good dispersion performance, high color matching accuracy, stable performance, convenient use, no pollution and easy storage.

release agent
The basic materials of mold release agents belong to organo-organochlorosilanes and organoalkoxysilanes, among which it can be further divided into methylethoxysilane, phenylchlorosilane and phenylethoxysilane and other organic compounds. Liquid use-type auxiliary products are generally sprayed on molds and materials that are difficult to fall off of high-viscosity materials as benchmarks. The main function in the silicone product industry is to spray directly on the surface of the mold to allow the silicone rubber raw materials to be quickly demolded after molding.

Silicone rubber surface treatment agent
Silicone rubber surface treatment agent: It is a kind of surface activator with 2 applications, commonly known as silicone treatment agent, ①Silica gel sticks double-sided adhesive, solves the problem of silicone sticking double-sided adhesive, direct paste, can not stick. ②When the processing agent silicone sticks to the metal plastic material, the adhesion of the instant glue to the glue is improved, and the bonding is more firm.
