Moulding Rubber

Sylmasta Silicone Moulding Rubber

Sylmasta Moulding Rubber is professional quality silicone rubber used for making high-quality, reusable moulds. A range of hardnesses are available as well as two specialist grades – one certified as safe for use with food and casting ultra-clear resins, and one designed for the casting of white metals.

Grade 370 is the softest grade of Sylmasta Silicone Moulding Rubber used for creating moulds with deep undercuts
Grade 380 is the medium, all-purpose grade of Sylmasta Silicone Rubber. It is stiffer than Grade 370 for better dimensional stability
Grade 390 is the stiffest grade of Sylmasta Silicone Moulding Rubber with its high dimensional stability making it ideal for larger moulds
Grade 375 is a high temperature grade of moulding rubber suitable for the casting of white metals
Grade 400 is for the casting of clear polyurethane resins to create water clear casts. It is certified food safe
Mould Release Agent is used to prevent the silicone moulding rubber from sticking to itself during the making of split moulds
Resins

Casting Resins

Polycast Casting Resins are non-shrink polyurethane resins for creating high-quality resin casts in silicone moulds. A range of thicknesses and cure speeds are available. Polycast Resins set to beige as standard. Should a specific coloured casting resin be required, then we have the capability to custom-make a resin to any RAL or PANTONE colour.

G27 White has been specifically designed for those seeking a white curing resin. Also available is Sylmasta CPU31 ClearCast, an optically clear, non-yellowing polyurethane resin resistant to UV for producing water-clear casts.

PolyCast G26 is a medium viscosity casting resin with a pot life of 3-4 minutes and a de-mould time of 30 minutes to 10mm
PolyCast G27 is a low viscosity casting resin with a pot life of 150 seconds and a de-mould time of 25 minutes to 10mm
Polycast G27LV is a very low viscosity casting resin with a pot life of 2 minutes and a de-mould time of 15 minutes to 10mm
