Three polyurethanes that combine good impact strength and high heat resistance (to 346 F) are newly available for casting thermoplasticlike prototypes for large automotive parts, sterilizable medical products, and equipment components with intricate design details.

Three polyurethanes that combine good impact strength and high heat resistance (to 346 F) are newly available for casting thermoplasticlike prototypes for large automotive parts, sterilizable medical products, and equipment components with intricate design details. TP-4004, 4006, and 4007 from Innovative Polymers, Inc., St. Johns, Mich., have 65 to 80 Shore D hardness and stiffness resembling TPO, ABS, and PC, respectively. A new mercury-free catalyst system is said to combine a long working life with gel times of 10 to 12 min at room temperature, early green strength, and a fast final cure.
