Product Description


Liquid Silicone Rubber For Medical Grade Platinum Cured Fantastic Durability  For Footcare Insole






LSR RH 6250-50YH® is a kind of two-component liquid silicone rubber for injection molding processes, consisting of part A and part B. It can be used to produce electronics keys supplies with the high rebound and good resistance to yellow. All LSR are platinum cured (vulcanized) materials which are mixed in a 1: 1 ratio by weight.

Here is a look at the LSR molding process:


1. LSR A + B components typically come in a 5-gallon pail or 55-gallon drum. A process controlled pumping kit presses down on the buckets to force the material into the static mixer and feed into the injection unit.

2. Then, streams of pigment can be added and controlled. In the injection, press material will be mixed together additionally with a screw and pushed forward to create a “shot” of material, or the amount needed to fill the mold.

3. After the material is injected into the mold, it will then stay clamped together to cure the LSR. Then, either an operator or a robot will remove the cured product from the mold
