Description

Grade 400 is the grade of Sylmasta moulding rubber suitable for use with casting clear polyurethane resins which is also certified as safe for food casting.

Its high tear strength permits castings to be made with larger than normal under cuts. It has excellent dimensional stability, extremely low shrinkage, high detail pickup and is chemically resistant.

Grade 400 is the only grade of silicone moulding rubber which should be used with Sylmasta CPU31 ClearCast Casting Resin. Using other grades will result in imperfect hardening.

It is a certified food safe moulding rubber which complies with FDA regulation CFR 177. It is 2600 compliant for fatty and aqueous foods EC 1935/2004 and EC 10/2011 and can be used for casting chocolate, icing, ice and other food substances.

Grade 400 Rubber can be purchased as part of our Sylmasta Clear Casting Kit. Each Kit also contains CPU31 ClearCast Casting Resin, Release Agent and all the other equipment needed to create moulds and begin producing transparent resin casts at a cheaper cost than when purchasing products separately.
