Read silicone foam material


For most people, "silicone" is a very strange name. In many cases, formula engineers and consumers will mistakenly think that organosilicon is a petrochemical product extracted from petroleum. However, the fact is that organosilicon comes from sand. Sand, also known as quartz, is composed of two of the most abundant elements on earth - oxygen and silicon, mainly composed of silicon dioxide.


As a kind of environmental protection material with excellent performance, organosilicon has run through all aspects of life unconsciously, from clothes, food, houses, cars, high-speed rail, roads and bridges


Life is inseparable from silicone, now so, the future is more!


Organosilicon, also known as silicone or siloxane, is a kind of organosiloxane polymer formed by the alternation of silicon and oxygen in the main chain. Because its structure contains both "organic group" and "inorganic structure", it has both organic and inorganic chemical properties.


As one of the uses of silicone rubber, silicone rubber foam material not only has excellent properties of silicone rubber itself, but also has the characteristics of foam material, and it is widely used in aerospace, automobile, power electronics, military industry and other fields.


With the development of rail transit industry towards high speed, safety, comfort and environmental protection, higher requirements are put forward for high polymer materials for rail vehicles. As a key component of rail vehicles, seat products have large demand, high technology maturity and high industrial chain maturity. Silicone rubber foam material is a kind of porous, low-density, compressible polymer elastomer material, which is made of various silicone oil, fillers, crosslinking, foaming agent and so on, after being mixed evenly and foamed and vulcanized at room temperature / high temperature. Compared with polyurethane foam, silicone foam can meet the requirements of EN45545-2 in terms of flame retardancy, the foam density is 0.08~0.15g/cm3, the service life is up to 2~4 times of polyurethane foam, and it is also superior to polyurethane foam in terms of comfort, foam density and environmental protection. Therefore, it has greater application prospects in aerospace, rail transportation and high-end automotive industry.


Silicone rubber foam takes into account the high elasticity of silicone rubber and the sound absorption and damping properties of foam. It is widely used in seat, damping pad, gasket, sound insulation material, insulation material, aviation insulation material and other high performance materials.


Seat cushion, backrest


Silicone foam can be used as seat, backrest and so on for rail vehicle seats. It can meet the stringent flame retardant requirements, and has outstanding characteristics such as long service life, excellent environmental protection performance and good comfort.
