China supplier liquid silicone rubber Direct Human Contact with Siloxanes (Silicones) – Safety
A Liquid Silicone Rubber material is a two-part platinum-cured elastomer that can be injected into a mold cavity to manufacture a part.
LSR is very versatile in the elastomer industry and is seen across a whole spectrum of parts from consumer products to medical devices and everything in between.
Most silicone rubber varieties share in common naturally-occurring qualities of high electrical insulation, resistance to extreme temperatures, chemical inertness and resilience in harsh environments.
Ruihe RH6250 SERIES Liquid Silicone Rubber (F-LSR) is specifically designed for liquid injection molding.
The product is supplied as a two component, soft fluorosilicone paste. It heat cures to a 60 durometer material.
The cured rubber product is resistant to a wide variety of solvents and chemicals over a wide temperature range
of -63 to +175°C (-82° to +347°F) under immersion conditions, and up to +225°C (+437°F) in dry heat.
