When Are Black Polypro and Copoly Ready to Pull?


Jeff Wilson, Business Development Manager of Orthotics and Prosthetics shares tips to determine when black homopolymer polypropylene (polypro) or black copolymer polyproylene (copoly) are at their ideal forming temperature. 

Polypropylene is used in the manufacturing of upper and lower extremity orthoses and prosthetics. Known for being easy to fabricate, polypropylene is easy to drape, blister form and seam. Polypropylene is also easy to decorate with transfer patterns. 

Polypropylene is available in homopolymer, carbon reinforced homopolymer, and copolymer grades. Have a question about O&P materials? Ask a Plastics Expert.

Length of time to reach temperature will vary depending on your oven.
