Silicone rubber with high temperature resistance, ozone resistance, chemical inertness and non adhesion to the plastic, so it is widely used for processing hot sticky products, has formed a series of products, such as: various specifications of rubber roller, rubber roller, large copier heat-resistant plastic thermal coated with plastic extrusion rollers and traction rollers etc., organic silicon rubber today tell us, is a metal or other material as core, coated with heat-resistant silicone rubber made.

The silicone rubber is composed of silicone rubber core and coupling agent, and is formed by high temperature and high pressure curing. Silicone rubber air permeability is good, its permeability is natural rubber and butyl rubber, such as ordinary rubber, dozens of times or even a hundred times, but also different gas permeability difference. The special coupling agent is used in the bonding between the silicon rubber and the roller core, and the adhesive is average and firm. Heat resistant silicone rubber rollers has the characteristics of high temperature resistant silicone rubber, because in all kinds of rubber, is the most wide working temperature range, can be used between -100 degrees to 350 degrees; tear resistance than general silicone rubber to improve heat resistant silicone rubber.

Silicone rubber after combustion, will produce silica, silica as an insulator, and can ensure the equipment to work, it also has excellent electrical insulation properties; the chemical inertness of silicone rubber, silicone rubber roller and heat so tasteless, there is no harm to the body; mildew resistance is also very good, but it also has the advantages of high strength, good viscosity at the same time, also can withstand generated in operation under the environment of high temperature in high speed pressure and shear stress, so it is widely used in industry but the heat resistant silicone, silicone rubber rollers prices generally more expensive, at high temperature can be used, if used at room temperature, do not need to choose this kind of heat-resistant silicone rubber and polyurethane rollers good wear resistance selection would be more appropriate.
