High-impact, Rapid-setting Polyurethane Introduced
EAST LANSING, Mich., May 13, 2003 - A new high-impact polyurethane that will enable prototypers to quickly produce polypropylene-like parts has joined the RenPIM(TM) polyurethane product line, it was announced today by the RenShape® Solutions Tooling Group of Vantico A&T US Inc. at Rapid Prototyping & Manufacturing 2003 in Chicago.
A second-generation rapid-setting polyurethane, high-performance RenPIM 6490 has a gel time of 70 to 80 seconds and a demold time of 30 to 40 minutes. The new Shore 78D product is easy to handle with a mix ratio of 2:1 by volume. Once cured, it has a flexural modulus of 166,000 psi, heat deflection temperature of 154°F (68°C) after a thermal postcure and notched Izod impact strength of 1.7 ft.-lb./in.
Other second-generation polyurethanes available from the RenShape Solutions Tooling Group include RenPIM 6462 Fast and RenPIM 6486 Fast. Both products are ideal for high-impact applications. RenPIM 6462 Fast features a notched Izod impact strength of 2.3 ft.-lb./in. and a high heat deflection temperature of 221°F (105°C) after a thermal postcure to simulate high density polyethylene. RenPIM 6486 Fast is an ultra-high impact strength (5.4 ft.-lb./in.) polyurethane with high elongation of 173% to simulate TPO and polyethylene.
