RTV Silicone Moulding Rubbers

Mouldmaking RTV silicones are used to produce high-quality, negative moulds of almost any object, component or figure with very accurate detail reproduction – whether it be for architecture and industrial design, large-scale production parts, jewellery, or food moulding. These mouldmaking silicone rubbers are flexible but durable even after many uses.

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, which use platinum-based catalyst.

CHT’s mouldmaking silicone RTV key physical properties:

  • Range of durometers/hardnesses
  • Range of viscosities
  • Compatibility with silicone fluids to increase softness
  • Flexibility with mixing ratios of the base and catalyst
  • Good self-releasing properties
  • Low and high tear strengths available
  • Low shrinkage
  • Excellent dimensional stability
  • Chemical resistance
  • Fine detail replication

Various product characteristics can be modified to achieve your desired process requirements and final properties including:

  • Viscosity/Durometer/Hardness
  • Translucent grades for pigmentation
  • Work Life/Pot life
  • Rheology
  • Surface feel

Addition Cure Silicones

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

General Attributes:

  • High tear and tensile strength
  • Very low shrinkage
  • Fine detail reproduction
  • Extensive range of hardnesses
  • Choice of catalyst and thixotroping agent

Condensation Cure Silicones

Condensation cure silicones are either 1-part or 2-part systems that utilise a tin based catalyst to cure.

General Attributes:

  • Range of tear strengths
  • Good extended mould life
  • Fine detail reproduction
  • Extensive range of hardnesses
  • Choice of catalyst and thixotroping agent

To learn more, visit our Condensation Cure Mouldmaking page.

Food Grade

Addition cure moulding rubbers have been formulated to meet FDA and EU tests for use with Aqueous and Fatty foods. The tests and results are product specific and the Technical Data should be consulted for exact specification.

Common applications:

  • Icing sugar moulding for cake decoration and confectionary
  • Chocolate moulding for confectionary

For technical assistance or sample requests, please visit our contact page.Rapid Prototyping

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, with detailed reproduction, which allows further product development.

General Attributes:

  • Fine detail reproduction
  • Dimensional stability
  • Self-releasing
  • High transparency
  • Very good resistance to chemicals
