Optical silicone must satisfy not only optical and molding requirements but also safety and aging resistance when used in food-contact and outdoor applications. Conventional materials often struggle to meet the needs of multiple scenarios.
A liquid optical silicone rubber features food-grade properties enabled by platinum-catalyzed technology, excellent UV resistance and heat resistance, as well as compatibility with both injection molding and casting processes. It has become an all-round optical material for outdoor, daily and food-contact scenarios.
Food-Grade Safety: A Key Highlight
Produced via platinum-catalyzed technology with no harmful additives, this product fully complies with food industry standards. Transparent bottles, cups and other food-contact items made from it are safe and non-toxic for direct food contact, without releasing unpleasant odors or hazardous substances. It combines crystal-clear aesthetics with reliable safety, solving the pain point that common optical materials cannot be used for food containers.
Outstanding Weather Resistance
With superior UV resistance and heat resistance, finished products easily withstand long-term outdoor UV exposure and intense heat without yellowing, aging or light transmittance decline. It is especially suitable for outdoor optical components in automotive lighting, maintaining stable performance and appearance after prolonged use.
Excellent Processability for Industrial Production
The full series has a viscosity range of 35,000–50,000 mPa·s, perfectly matching both injection molding and casting.
-
Injection molding: enables precise filling of precision molds for fine products such as light guide columns and optical lenses.
-
Casting: achieves one-piece molding for regular products like bottles and cups.
Molded products feature sharp edges, smooth surfaces and high yield rates.
From food-contact transparent containers and personal optical accessories to outdoor automotive lighting optical parts, this optical silicone stands out as a high-performance material across industries, balancing safety, performance and processing convenience.
