Casting polyurethanes

Casting polyurethanes for figures, prototypes, flexible parts or insulating fills. The intended result guides the choice between rigid resins, elastomers and foams.

What to consider when choosing

Figures, housings and rigid prototypes

Rigid polyurethane resins include PU-31 for miniatures, housings and moulded parts, and PR700 for ABS-like parts. Compare the time available to fill the mould and the process: vacuum is not recommended for PU-31, whereas PR700 allows casting with or without vacuum.

Elastic parts and insulation

HPE-V2 elastomers offer a choice of hardness for parts, moulds and patterns subjected to loads. For filling and insulating cold rooms, tanks or walls, browse polyurethane casting foams. Select foam by volume and insulation function, not as a substitute for a solid rigid part. Check the components and system conditions in the technical data sheet before choosing a pack size.
