Polypropylene copolymer has more resilience than homopolymer polypropylene. Copolymer polypropylene has less rigidity and processes at a slightly lower temperature. These qualities allow copolymer polypropylene to be spot modified more easily than homopolymer polypropylenes Copolymer polypropylenes are more commonly used in orthotics, but are gaining acceptance for AK and BK sockets. Typical shrinkage is 1 1/2 percent to 2 percent.
