① high degree of transparency. Organic silicone is the best polymer transparent material, light transmission rate of 92%, high light transmission than silica gel. Known as the man-made small solar lamp solar light is made of quartz, because quartz can be completely through the UV. Ordinary silica gel only 0.6% of UV rays through, but was able, through 73% organic silica. ② high mechanical strength. Molecular weight silicone is about 2 million, is the long-chain polymers, and the formation of molecular chains is very soft, so a high strength silicone, tensile and impact the ability of higher than ordinary silica gel 7-18 times. There is a heated and stretched processed organic silica gel, the molecular chains arranged very orderly, and the material toughness has improved significantly. With a nail into this organic silica gel, even nail penetration, and organic silica gel does not crack. This silicone is not the same bullet broke into pieces after the breakdown. Therefore, the stretch processing of organic silicone gel can be used as bullet-proof, also used as military aircraft canopy. ③ weight. Density of silicone 1.18kg/dm 3, the same size material, its weight is only half the ordinary silica gel, aluminum (of the light metal) of 43%. ④ easy to process. Silicone can be used not only for cutting lathe, drilling machine for drilling, and can use acetone, chloroform and other adhesive devices into a variety of shapes, also use blow molding, injection, extrusion and other methods of plastic molding process to the National Cheng Kung University cockpit cover, small to dentures and denture products and other diverse.
