23、lly, PP-RCT has referred to a polypropyl-ene random copolymer with modified crystallinity that deliversperformance characteristics referenced in ISO15874. However,recent developments make it possible to attain the PP-RCTperformance requirements other than through modification ofcrystallinity.3.2.1.2

24、 DiscussionThis term is also used for finishedcompound which comprises the PP-R or PP-RCT resin andadditives such as colorants, UV inhibitors, and stabilizers.Polypropylene random copolymers containing more than oneadditional monomer are often referred to as “terpolymers.”3.2.2 plastic-to-metal tran
