Copolymer Polypropylene

Copolymer polypropylene is now available from Allied O&P Supply in red, light blue, royal blue, purple, yellow, light pink, and brown. Copolymer polypro­pylene has some flexibility and good crack resistance, but it is more resilient and less rigid than homopolymers, and it processes at a lower tem­perature, all of which facilitate spot modification. The recommended oven temperature is 350° to 375° F. Typical shrinkage is 1.5% to 2%. Copolymer polypropylene has a yield point of 3400 psi, elongation at yield of 11%, and a Shore D hardness of 72 durometer. The material is available in 1/8″ and 3/16″ thicknesses.
