LSR Liquid Silicone Rubber

High resilience, tear resistance, environmental protection and stability

LSR ( Liquid Silicone Rubber) differs from HTV in manufacture. The product properties of LSR are well-prepared by the manufacturer upon production. It has the broadest operating temperature range (-100°C ~ 350°C) with excellent high and low temperatures resistance. Depending on factors, it includes general purpose, solvent and oil resistance, high-tear strength, self-adhesive, heat resistance, flame retardancy, self-lubricating, electrical conductivity, and high optical transparency.

GX has been engaged in the research and manufacture of LSR since 2012. We have the ability to manufacture high quality liquid silicone rubber for general purpose, flame retardant LSR, low volatility LSR, high temperature resistant LSR, and more.

1. Basic Knowledge of LSR Silicon

Like other rubbers, you can make various products out of liquid silicone rubber (LSR). This variant includes two agents:

    • A and B
    • mixed 1:1

then injected into the mold through an LSR injection molding equipment. LSR is suitable for products where the typical rubber isn’t enough.

This rubber variant requires large-scale continuous production of silicone polymer with:

    • fast vulcanization speed
    • low molding temperature

You can also combine it with composite applications. Moreover, the biocompatibility of liquid silicone rubber is a crucial product requirement.

2. General properties of GX LSR silicone rabber

GX-Silicone rubber compounds have characteristics of both inorganic and organic materials, and offer a number of advantages not found in other organic rubbers.

4. Delivery forms of GX LSR Silicone Rubber

GX-Silicon LSR liquid silicone rubber are supplied as 2-component systems.

The A component contains the platinum catalyst, while the B component contains the cross linker.

    • 20-kg pails with a PE inliner (ø inside 280 mm)
    • 200-kg drums with a PE inliner (ø inside 571.5 mm)

5. Storage of GX LSR

General Information on Storing GX Liquid Silicone Rubber.

  • Store in closed containers in cool rooms at 0 – 30 °C.
  • Higher average temperatures may shorten the shelf life. 
  • Do not expose to direct sunlight.
  • When opening the container, make sure that no dirt falls onto the surface of the rubber.
