SBR
Basic Information
Polypropylene copolymer (PPC) is a bit softer but has better impact strength, and is tougher and more durable than homopolymer polypropylene. Copolymer polypropylene tends to have better stress crack resistance and low temperature toughness than homopolymer at the expense of quite small reductions in other properties.
