Liquid Silicone Rubber for general purpose applications.
Producing quality parts rapidly is essential in the LSR molding market. Liquid injection molding provides the most efficient and economically viable process using Liquid Silicone Rubber (LSR). Elkem Silicones offers a robust general purpose product range of LSR materials including durometers from 01-70 Shore A. These materials are specifically designed with a fast cure and excellent mold release as well as excellent physical and mechanical properties.
Liquid injection molding is the process used with liquid silicone rubber (LSR) to fix the material from an uncured state into a cured part.
The highly viscous LSR is extracted from drums or pails using a dosing unit and injected into a closed mold in the press.
The mold is then heated, and the heat combined with pressure applied to the LSR results in the rubber becoming a solid part.
Application
For the injection molding of parts requiring a material with a medium durometer including: molded rubber stoppers,
gaskets, seals, valves, o-rings and other precision parts Suitable for over-molding applications
Can be used with Ruihe’s Healthcare color masterbatches for applications requiring colored silicones
