Polypropylene is available in both homopolymer and copolymer grades.
Homopolymer Polypropylene
Homopolymer polypropylene is stronger and stiffer than copolymer.
Copolymer Polypropylene
Copolymer polypropylene is a bit softer, but it is tougher and more durable than homopolymer polypropylene. Copolymer polypropylene tends to have better stress crack resistance and low temperature toughness than homopolymer polypropylene.
