Polypropylene Copolymer (PPCO)
PPCO is a bit softer than PPH but has a better impact strength, is tougher, more durable, and has a lower temperature. Additionally, PPCO tends to have a better stress crack resistance than PPH. Polypropylene is not vulnerable to environmental stress cracking failures when exposed to soaps, wetting agents, and alcohols, unlike many other polymers.
