Low Viscosity Liquid Silicone Rubber (LSR) for Injection Molding

LSR2012-05A/B, LSR2012-20A/B

Product Description
This is a low viscosity liquid silicone rubber made from a two-component system and cured by platinum. Not containing heavy metal and aromatic, the viscoelastic material is non-hazardous to human body. With two components mixed by a ratio of 1:1, the low viscosity LSR is suitable for injection molding.

1. High mechanical strength;
2. Quick curing under high temperature;
3. High processing efficiency;
4. At 20°C, A/B mixture as sealed can be safely operated for 5 days. If temperature rises, time reduces.

The low viscosity liquid silicone rubber is ideal for making sex toys, emulational masks, artificial limb, film props, etc.

20kg/pail or 200kg/pail
