TSE Industries Millathane® 76 Millable Polyester Polyurethane Rubber, 40 PHR Non-Black, Oyster Shell Calcium Carbonate
Categories: Polymer; Thermoset; Polyurethane, TS; Thermoset Polyurethane, Elastomer, Unreinforced; Rubber or Thermoset Elastomer (TSE)

Material Notes: Millathane® 76 is a very suitable choice for use in products such as bushings, small copier rolls; automotive applications — bumpers, o-rings, hydraulic seals, belts, gaskets, solid tires — and many other high performance polyurethane applications. Millathane 76 can be vulcanized by sulfur or peroxide cured systems.

Curing of Millathane®76 can easily be done with many types of peroxides. Millathane76 peroxide vulcanizates have superior compression set, greater heat stability, and are more resistant to reversion than sulfur cures..
