chemical name for silicone, is [ Si0 ( CHs) 2] Based on monomer polymer, is more polydimethylsiloxane. Varies with the size of molecular weight and degree of polymerization of divided into colorless transparent silicone products fluid ( Liquid silicone products) And thick solid silica gel and the intensity of large silicon elastic membrane. Chemical properties of non-toxic, odorless, resistant to heat, light for the skin and mucous membranes, generally accepted to be safe. Early 60 s silicone fluid used for burn wounds from soaking treatment, found that can promote the focal chi's for complete separation, early formation of granulation tissue, prevent wound infection and promote early contracture of joint activities, particularly in the treatment of burn obtain good effect. Liquid silicone injection, also a cross used for soft tissue sag after products cannot be pure and appear heavier tissue response was to stop using 13). 奎因( 1985) Report of silicon gel has the following properties: (1) tension measurement shows that the silicon gel 41. 8% of the extension, similar to the skin, and therefore used for joints don't limit their activities. Bacterial cultivation experiments show that the silicon gel for bacteria appear a gender, also does not inhibit or change the bacterial growth. (3) for water vapor appear a rate of 4. 5 g / / h, which is about the skin ( ( 8. 5 g/ m² / h) In the half. Extremely XiMiao electron microscopy showed that silicon gel surface smooth, no pore.
