| Silopren LSR 7060 liquid silicone rubber is a two-component, high-transparency, medium-hardness, low-viscosity, fast-cure speed and ultra clear liquid silicone rubber (LSR). Providing good optical clarity, Silopren LSR 7060 liquid silicone rubber combines typical LSR properties, such as high temperature stability and flowability, with excellent UV and blue light stability. As a result, molded lenses produced using this material can exhibit excellent durability and maintain optical clarity, even if exposed to high temperatures or UV light. Due to its high flowability, Silopren LSR 7060 liquid silicone rubber can help enable excellence in manufacturing complex and micro-structure optical lenses, even in large quantities, utilizing the injection and compression molding processes. Key Features and Typical Benefits Optical Clarity Durability Design Freedom Productivity Potential Applications Interior and exterior lighting – lenses and other illumination optics Automotive lighting – lenses and light guides Electronics – Mobile phones, flash lenses, sensing lenses, light guides and other optics Solar – primary optics for concentrating PVs&& |
