Mold Temperature 125°F 200°F 50°C 90°C Notes These guidelines are based on lab results, and their values may not reflect actual processes using different machinery.

At the scientific level, rubber and silicone are both thermoset materials, meaning once the material is molded it is “set” and cannot be broken down to be molded again. molded into a unique design This ability to flow freely in a near-melted state is an important property because it allows TPEs to be molded into any shape you want.

Achieve complex designs without expensive tooling – Gravi-Tech material can be injection molded into unique part shapes utilizing lower cost molds made of P20 or H13 steel. Add weight while simplifying your processing steps – Simplify your manufacturing process by injection molding a weighted, finished part in one step rather than adding a metal weight. Reduce the number of parts – By injection molding Gravi-Tech material, you will no longer need to assemble multiple parts to achieve added weight.
