1.Performance of Silica Gel Seal Ring
（1） It has excellent sealing performance, waterproof and leakproof.
（2）Fresh-keeping effect is good, completely non-toxic and tasteless.
（3）It can be heated at high temperature without distortion and producing harmful substances.
（4）Good tensile performance, after special inspection and testing.
（5）Long-term use will not fade.
（6）Corona resistance, arc resistance, high and low temperature resistance, good aging resistance, high temperature resistance, in line with FDA and SGS standards.
2. Advantages of Silica Gel Sealing Ring
Heat resistance: Silicone rubber has much better heat resistance than ordinary rubber. It can be used almost forever at 150 degrees without performance change. It can be used for 10 000 hours continuously at 200 degrees and for a period of time at 350 degrees. Widely used in heat-resistant occasions, hot water bottle sealing ring, pressure cooker ring heat-resistant handle.
Cold resistance: the lateness of ordinary rubber is - 20 30 that is, silicone rubber still has good elasticity at - 60 70 and some special formulations of silicone rubber can also withstand extremely low temperature , such as: low temperature sealing ring.
3. Defects of Silica Gel Seal Ring
It is not recommended to be used in most thickly condensed solvents, oils, thickly condensed acids and diluted sodium hydroxide.
