Silicone Rubber for Cell Phone Keypad (High Temperature Cured)

Model No.
LSR6915-70A/B, LSR6915-80A/B

Product Description
This transparent two-component platinum catalyzed liquid silicone rubber is suitable for high temperature injection molding. The most outstanding characteristic is that it can perform fast curing under high temperature conditions. The cured form features good rebound ability, high tear strength, excellent thermal stability, low yellowing rate, low shrink rate, and superior anti-ageing property, etc. Due to its amazing properties, this liquid silicone rubber is largely used to make P+R cell phone keypads.

Our silicone rubber for cell phone keypad is available in 20kg or 200kg barrels.
