Heat-resistant Silicone Rubber

Description

Silicone rubber for making heat-resistant molds for casting low-melting point metals like tin.

Properties and Application:

– Easy to process
– Easy mixing of components 1:1 by weight
– Very good flowability, mixture is easily pourable
– Cross-linking into a resilient, rubber-elastic vulcanizate without heat of reaction
– Temporarily temperature resistant up to 450 degrees Celsius
– High tear strength and high flexibility
– Very high reproduction fidelity
– For making molds for casting with low-melting point metals (tin, lead) and bismuth alloys

The Silicone Rubber HB is very well suited for making heat-resistant molds (short-term, at the time of pouring, no continuous temperature resistance) for casting with low-melting point metals.
At the same time, the molds are elastic, durable, and also suitable for reproducing undercuts.

When casting with low-melting point metals, ensure the mold is absolutely dry, and the mold should be treated with talcum powder as a release and flow agent before each casting.
This will result in better casting results and protect the mold from burns.

With Silicone Rubber HB, single- or multi-part molds can be made,
for replicating original models made of wood, glass, metal, plastic, wax, ceramic casting compounds.
You can also cast all water-soluble casting materials in the molds you make, such as
relief casting compounds like Stewalin, Keraflott or plaster, Keramin, Alabit, modeling and model-building plaster, casting clay, cement, concrete, etc.

The silicone has not been tested for skin and mucous membrane compatibility, nor for use in connection with food.
If you are looking for silicones that you want to use in connection with food or body molding, please ask us.
We also have suitable materials for this in our range.
