Silicon rubber gasket has excellent heat resistance, cold resistance, dielectric, ozone resistance and corrosion resistance and other properties, properties of silicone rubber floor matspad is a prominent use temperature is broad, in -60 ℃ (or lower temperature) to 250 ℃ (or high temperature) under long-term use. But the tensile strength and tearing strength poor mechanical properties of silicone rubber pad, at room temperature, the physical and mechanical properties than most synthetic rubber pad, and in addition to silicone, fluorosilicone plastic blocks pad, silicone rubber pad general oil resistance, solvent resistance is poor, so the silicon rubber pad is not suitable for ordinary condition however, very suitable for many special occasions.
It is worth mentioning that, in biomedical engineering, polymer materials plays a very important role, and the silicon rubber pad is a kind of very important medical polymer materials, it has excellent physiological inert, non-toxic, tasteless, no corrosion, anti coagulation, and the good compatibility, can withstand sterilization conditions harsh. According to the need to be processed into pipe, sheet, film and special-shaped components, can be used as medical devices, artificial organs, etc..
Silicon rubber pad is divided into room temperature vulcanized silicone rubber pad and high temperature vulcanized silicone rubber pad. The room temperature vulcanized siliconemat rubberpad according to the composition, curing mechanism and the use of technology can be divided into three types, namely, single component room temperature vulcanized silicone rubber pad, two-component RTV silicone rubber pad and double component addition type room temperature vulcanized silicone rubber pad. Room temperature vulcanized silicone rubber pad of the three series of each has its characteristics: one component room temperature vulcanized silicone rubber pad has the advantages of convenient use, but deep curing speed is difficult; two component room temperature vulcanized silicone rubber pad has the advantages of the curing time is not heat, shrinkage rate is very small, not swollen, no should force, curing can be carried out simultaneously in internal and surface, can deep sulfide; the curing time and room temperature vulcanizing silicone rubber pad is mainly determined by temperature.
Silicon rubber pad according to the vulcanization characteristics can be divided into heat vulcanized silicone rubber pad and room temperature vulcanized silicone rubber pad two. According to the performance and the use of different can be divided into general type, ultra low temperature resistant type, super high temperature resistant, high strength type, oil type, medical etc.. Used by the different monomers, which can be divided into methyl vinyl silicone rubber, methyl phenyl vinyl silicone rubber, fluorine silicon, silicon rubber, nitrile.
