Silicone rubber is a new type of special polymer material, also known as environ-mentally friendly polymer material, is a non-toxic, tasteless, colorless, transparentelastomer. lts initial raw material is a colorless and transparent elastomer with Si-0bond as the main chain structure prepared by a series of synthesis, separation, watercracking, polymerization and other processes after silicon ore smelting, grinding andprocessing to obtain silicon powder.Silicone rubber is currently all rubber varieties in the high and low temperatureperformance of the best (-40-350C), it also has excellent thermal oxidation stability.aging resistance, flame retardant, high permeability, electrical insulation, non-toxicand tasteless, physiological inertia, etc. Widely used in aerospace, electric power,modern communications, electronics, petrochemical, automotive, textile, medicine,food processing and daily life, known as "industrial MSG", is one of the most promis.ing new material varieties in the 21st century. lt has become an indispensable and ir-replaceable important elastomer material in various fields of aerospace science andtechnology, modern national defense, modern industry and modern life.The excellent properties of silicone rubber materials are constantly being recog.nized and accepted by people, and continue to replace the traditional rubber elasto-mer materials and sealing materials, every year will increase the use of silicone rubbermaterials in many application fields, a wide range of use, there is a larger domesticand foreign market development space, market prospects, industry prospects arevery promising.
