We now have in stock 3 grades of hardness of PU Elastomer! Ideal for lower cost, longer lasting moulds. PU are well known for their low  shrink and excellent durability!

NOTE: These are not as safe as RTV Silicones. Some contain TDI, MDI or other reprotoxins. They are certainly not for use by minors or younger casters and really are for professional use! Recommended for use in good ventilation and with gloves & apron!

The three grades in stock at present cover 40, 60 and 80 Shore A. They can be used in RTV Silicones or as Moulds, however please use a suitable release agent. TOMPS Liqui Wax 1 is an ideal companion for any PU Elastomer.

We offer a 5% discount on 5 kits and 10% on more. Why buy a bigger kit only to have its shelf life compromised by opening it and exposing it to moisture.
