High temperature silicone casing surface structure containing both " organic group" , but also contain " inorganic structure" , this particular composition and molecular structure so that it sets the characteristics of organic and inorganic functions in one. Compared with other polymer materials , the most prominent is the high temperature performance. Silicon - oxygen (Si-O) bond as the main chain structure, the key can be the key CC 82.6 kcal / mol , Si-O bond energy of 121 kcal / mole of organic silicon , so the thermal high stability, high temperature ( or radiation ) molecular bond is not broken , do not break down . Silicone is not only to high temperature , low temperature resistance, but also can be used in a very wide temperature range . Whether it is physical or chemical properties and mechanical properties, temperature dependence is very small.
