Rigid polyurethane casting resins

PU-31 for moulded parts and PR700 for ABS-like parts

PU-31 is described for figures, toy parts, frames, housings and prototypes, as well as automotive parts. Its high reactivity requires planning the mould filling; vacuum is not recommended. PR700 is intended for ABS-like parts and can be cast with or without vacuum: a useful process distinction when choosing, beyond pack size.

Choosing the mould and result

Browse mould-making silicones alongside the intended casting system. For an elastic rather than rigid part, compare polyurethane elastomers. Check the technical data sheet to confirm that hardness, working time and thermal resistance suit your prototype.
