CHT’s high performance mouldmaking silicones are designed to produce high-quality, negative moulds of almost any object, component or figure with very accurate detail reproduction.
Whether it be for industrial design (Rapid Prototyping), architectural applications, large-scale production parts, jewellery, or food moulding, mouldmaking silicone rubbers are flexible but durable even after multiple uses.
These room temperature vulcanising (RTV) silicone rubbers use two different types of silicone chemistry to form an elastomer. Condensation cure systems, which use a tin based catalyst, and addition cure systems with platinum-based catalyst.
CHT offers a great selection of products for mouldmaking purposes. However, finding the suited silicone for your application is not limited to our product portfolio.
Our technical team will partner with you to either modify specifications in a current product or custom formulate a new one to meet your exact requirements.
CHT’s mouldmaking silicones impress with the following physical properties:

Addition curing systems are 2-part liquid silicones. They utilise a platinum catalyst to cure by either room temperature vulcanisation (RTV) or heat to accelerate cure.
Condensation cure silicones are either 1-part or 2-part systems that utilise a tin based catalyst to cure.

Addition cure moulding rubbers have been formulated to meet FDA and EU tests for use with aqueous and fatty Foods.
Rapid prototyping methods often use silicone moulds to reproduce a limited number of prototype components from resin masters.This process enables rapid, low cost and uncomplicated production of prototypes and models.
The detailed reproduction supports further product development.
