The basic structual unit of the silicone product is the silicon-oxide chain section.The side chain is conneted to other organic groups through silicon atom.Therefore,there are both “organic group” and “inorganic group” in the silicone product.

This kind of particular composition and molecular structure enable the silicone product contains the features and functions of the two at the same time.Compare with other kind of polymer material,the outstanding characteristics about the silicone product is:

1.Temperature characteristics

The mian chian structual of the silicone product is silicon-oxygen bond,with C-C bond and SI-O bond playing their function,the silicone product can stay in a very steady state no matter under very hign or low pressure for very long time.Thus the temperature condition of silicone product is very loosen and wide.Moreover,the changes taken place in the silicone product is quite slight.

2.Weatherability

As the scientific research conclusion,the SI-O unparalleled key chain can not be decomposed by ultraviolet light and ozone readily.As a result,the silicone product has much better heat stability,radiation resistance and weatherability.The service life of the silicone product is normally several decades.
