Odorless Medical Grade Liquid Silicone Rubber For Medical Grade Platinum Cured For Footcare Insole
Description
Our LSR 6250-50YH liquid silicone rubber is a two-component material, and the silicone rubber includes Part A base silicone and Part B curing agent. The Part A base silicone and Part B curing agent can cure at room temperature by an addition reaction, it can be heating during the action, the higher temperature, the faster curing. All LSR are platinum cured (vulcanized) materials which are mixed in a 1: 1 ratio by weight.

Instructions
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 a 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
Applications
Our offerings also include products that meet FDA, BFR, and USP class 6 requirements or contain low levels of low-molecular-weight (LMW) siloxanes.
The material feels soft on the skin, which makes it an obvious choice for devices that contact the body.
