Silicones for Mould Making

Why are silicones used for Mould Making?

Silicone moulding rubber has many applications across a wide range of industries using various casting mediums. Silicone is chosen for its fine reproduction of detail, versatility, ease of use and physical strength.

Applications include:

  • Casting materials & applications
  • Wax for candles and use in the lost wax process for bronze casting
  • Polyurethane for mirror and picture frames, architectural mouldings
  • Polyester resin for giftware, figurines, sculptures
  • Plaster for covings and cornices, film studios, figurines, fireplaces
  • Ceramics for earthenware pottery
  • Low melt alloys for toys, models
  • Glass for auto windscreens
  • Stone filled resins for replication of works of art, fireplaces
