High Strength Liquid Silicone Rubber LED Secondary Lenses

high transparence high strength liquid silicone rubber LED secondary lenses

Description

RH5350-60KSA/B is platinum cured silicone rubber for silicone products.

This silicone rubber is packaged in A:B composition at 20 kg/barrel or 200 kg/barrel. The storage conditions are unmixed two-component sealed and stored at room temperature. It is important to note that this product should not be exposed to compounds containing N, P, and S, so as not to poison the platinum catalyst and affect the effect.

LSR is a two-component system that consists of a base silicone polymer and a curing agent. It is typically available in liquid form, allowing for easy and precise molding or casting into various shapes.

Heat resistance: LSR exhibits excellent thermal stability, making it suitable for applications where exposure to high temperatures is expected. It can withstand temperatures ranging from -50°C to 250°C (-58°F to 482°F) without significant deformation or degradation.

Flexibility and elasticity: LSR is highly flexible and elastic, enabling it to undergo repeated stretching or compression without permanent deformation. This property makes it ideal for applications requiring gaskets, seals, or any component that needs to withstand movement or vibration.

Chemical resistance: Liquid silicone rubber is resistant to a wide range of chemicals, including acids, bases, solvents, oils, and many other substances. This resistance makes LSR suitable for applications where exposure to harsh chemicals is likely.

Packaging & Storage

Available in 20kg pails or 200kg drums.

Store in a cool, dry place out of direct sunlight, use it within 12 months from the day of manufacture.
