RapidCast, Fast Cure Polyurethanes Print E-mail

The very fast-gelling polyurethanes in the Innovative Polymers RapidCast, Fast Cure product family are used for automated meter/mix dispensing into molds built from a variety of tooling materials. Several of the systems are also suitable for cartridge dispensing. RapidCast Shore D hardness polyurethanes are typically used for producing functional ABS- and polypropylene-like prototype parts. The product line includes UL 94 V-O flame retardant materials (two systems have yellow cards), a buffable, water clear lensmaking product, a FDA-compliant (CFR 21.177.1680) product for dry food contact and a room-temperature cure, high-heat material for under-hood automotive prototypes.

RapidCast, Fast Cure polyurethanes can be demolded after five to 30 minutes at room temperature and feature excellent flexural modulus and good elevated temperature performance.
