6250-50T® LSR Liquid Silicone Rubber High Stability Liquid Silicone Rubber for Scuba Mask
RUI-HE 6250-50T® is a kind of two-component liquid silicone rubber for injection molding processes, consisted of part A and part B. It can be used to produce electronics keys supplies with the high rebound and good resistance to yellow. All LSR are platinum cured (vulcanized) materials which are mixed in a 1: 1 ratio by weight.

Because of the outstanding properties, 6250-50T® liquid silicone rubber is particularly suitable for scuba mask, keys supplies, such as a computer keyboard.
Rui-He 6250-50T® Liquid silicone rubber obtained the following test certificate: RoHS, FDA, REACH, PAHS, ISO9001:2016, etc.
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.
This product cannot be contacted with compounds containing N, P, S to avoid affecting the catalytic effect of platinum.
Q: Why are some silicones specified as "addition cure"?
A: Some silicones are described as addition cured because the cure mechanism is a catalyst reaction between the component ingredients within the compound. These components need to be added together for the compound to cure hence the term addition. Addition cure compounds can be supplied as one, two or three component systems.
Q: Can silicone be used for high traffic surfaces?
A: Products made from silicone should not be used in high traffic applications because even the best high strength compounds have a relatively modest resistance to abrasion wear.
