Silicone rubber Overview

Silastic is a linear polyorganosiloxane as a base polymer ( gum ) , a crosslinking agent , reinforcing filler and other ingredients , as with the sulfide , and the resulting elastomer. It can be used in a wide temperature range from -100 ° C ~ 315 ° C, is less than any other elastomer . Is characterized by resistance to weathering , the experiment proved that you can use in the outdoor 100 to 150 years. As well as electrical insulation , hydrophobicity , anti- stickiness, excellent performance and biochemical compatibility , the elastomer is used for the modernization of the ordinary .

　　Silicone products products according to their shape, into mixing silicone rubber and liquid silicone rubber into two categories.

　　Mixing silicone rubber, heat is often referred to as silicone rubber , a high polymerization degree is linear ( siloxane structure 5000 to 10,000 units ) of the polyorganosiloxane with reinforcing fillers , extenders and fillers impart various performance additives formulated into the base material . When used with the vulcanizing machine, the molding vulcanized products. Due to the same general organic rubber plasticized static roller , with a vulcanizing agent, and other operations tableting process, so called mixing silicone rubber.

　　Mixing liquid silicone rubber and silicone rubber type , with the filler comprises a linear polyorganosiloxane moderate degree of polymerization of the base polymer , additives, various additives and formulated with a self-leveling or thixotropic base material . Generally do not have the use of large-scale processing equipment, according to the species and has purpose extrusion, injection type , after coating , or heat in the atmosphere vulcanized elastomer molding .
