Silopren LSR 7005 liquid silicone rubber is a two-component, high-transparency, low-hardness, low-viscosity, fast-cure speed and ultra clear liquid silicone rubber (LSR). Providing good optical clarity, Silopren LSR 7005 liquid silicone rubber combines typical LSR properties, such as high temperature stability and flowability, with excellent UV and blue light stability. As a result, optical parts produced using this material can exhibit excellent durability and maintain optical clarity, even if exposed to high temperatures or UV light. The very low hardness and low modulus help enable easy assembling and coupling of molded optical elements. Silopren LSR 7005 liquid silicone rubber is designed to be processed through LSR injection molding technology, which can help to produce high precision optical parts even in large quantities at a high efficiency.
