The Characteristics Of Silicone Rubber

- Mar 26, 2018-

Heat resistance: Silicone rubber than ordinary rubber has a much better heat resistance, can be used almost forever at 150 degrees without performance changes, can be used for 200 degrees continuous 10,000 hours, at 350 degrees can also be used for a period of time. Widely used in the requirements of heat-resistant occasions: Thermos bottle sealing ring pressure cooker ring heat-resistant handle

Cold resistance: ordinary rubber late-20 degrees ~-30 degrees, that is, silicone rubber in the 60 degree ~-70 still have a good elasticity, some special formulations of silicone rubber can withstand very low temperature.

Weather resistance: ordinary rubber in corona discharge of ozone under the action of rapid degradation, and silicone rubber is not affected by ozone. And for a long time in ultraviolet and other climatic conditions, its physical property has only a small change. Sealing materials for outdoor use

Electrical properties: Silicone rubber has a high resistivity and in a very wide temperature and frequency range of its resistance to maintain stability. At the same time, silicone rubber has good resistance to high voltage corona discharge and arc discharge. HV Insulator TV High pressure cap electrical components other

Conductivity: When adding conductive filler (such as carbon black), silicone rubber will have a keyboard conductive contact point

Thermal conductivity: When adding certain heat conduction filler, silicone rubber will have thermal conductivity of heat sink thermal seal pad copier, fax machine Heat Transfer Roller

Radiation: The resistance of silicone rubber containing phenyl greatly enhances electrical insulated cable power plant connectors

Flame Retardant: Silicone rubber itself can be ignited, but the addition of a small amount of flame retardant, it will be flame-retardant and self extinguishing, and because silicone rubber does not contain organic halide, so burning without smoke or release of toxic gas. A variety of fire-resistant and strict occasions

Permeability: Silicone rubber film than ordinary rubber and plastic wax film has better air permeability. Another characteristic is that it has a strong selectivity to different air permeability. Gas exchange membrane medical supplies artificial organs
