Cold Heat Resistant Anti Corrosion 1.78mm SIL Silicone O Ring
SIL Silicone Rubber o Ring seal Resistance to cold and heat Anti-corrosion insulation High toughness O rings
(Silicone rubber) The main chain of silica gel is formed by combining silicon (-si-o-si). It has excellent heat resistance, cold resistance, ozone resistance and atmospheric aging resistance. Has good electrical insulation properties. The tensile strength is worse than general rubber and it has no oil resistance.
·After formulating, the tensile strength can reach 1500PSI and the tear resistance can reach 88LBS
·Good elasticity and good compression distortion
·Good resistance to neutral solvents
·Excellent heat resistance
·Excellent cold resistance
·Excellent resistance to ozone and oxide erosion
·Excellent electrical insulation performance
·Insulation, good heat dissipation
· Seals or rubber parts used in the household appliance industry, such as electric kettles, electric irons, and microwave ovens.
· Seals or rubber parts in the electronics industry, such as mobile phone keys, shock absorbers in DVDs, and seals in cable joints.
· Seals on all kinds of articles that are in contact with the human body, such as kettles, drinking fountains, etc.
