Why is Liquid Silicone Rubber ideal for injection molding applications?
Liquid Silicone Rubber injection molding
Manufacturers in various industries, including automotive, healthcare, general industrial, infant care, consumer goods and electronics require easy-to-mold (and demold) low or high-viscosity rubber silicones to produce parts efficiently and cost-effectively.
Liquid silicone rubber (LSR) is the material of choice for injection molding applications. The silicone backbone is composed of repeating Si-O chains which are extremely flexible in nature giving this chemical structure unique properties such as a broad operating temperature range, weatherability, hydrophobicity, bio-inertness, electrical insulation, and a sustainable life span.
Liquid injection molding
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.
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.
