General Info
Duratron® CU60 PBI offers the highest heat resistance and mechanical property retention over 400°F of any unfilled plastic. It has better wear resistance and load carrying capabilities at extreme temperatures than any other reinforced or unreinforced engineering plastic. As an unreinforced material, Duratron® CU60 PBI is very “clean” in terms of ionic impurity and it does not outgas (except water). Duratron® CU60 PBI has excellent ultrasonic transparency as well as excellent thermal insulting properties. Other plastics in melt do not stick to PBI. These characteristics make it ideal for contact seals and insulator bushings in plastic production and molding equipment.

Resin Trade Names
Manufacturer Trade Names
Boedeker Plastics, Inc. stocks & supplies plastic sheet, rod, tube, film and custom profiles and machine parts from these shapes that are produced from plastic resin. In many cases the manufacturer of the shape has their own product trade name. If your specification calls for a specific resin grade or manufacturer trade name, we can supply a shape made from that resin to meet your specification or suggest an equal. If you require a specific resin or brand it must be specified at the time of order.
