PP homopolymer polypropylene is an economical material that offers a combination of outstanding physical, chemical, mechanical, thermal, and electrical properties not found in any other thermoplastic.
Compared to low or high-density polyethylene, pp homopolymer polypropylene has a lower impact strength, superior working temperature, and greater tensile strength. Polypropylene has excellent chemical resistance in corrosive environments where there are organic solvents, degreasing agents, or electrolytic attack, but poor resistance to aromatic, aliphatic, and chlorinated solvents. PP homopolymer polypropylene is lightweight, non-staining, and exhibits a low moisture absorption rate.
It’s ideal for the transfer of hot liquids and gases, and in vacuum system atmospheres with high heat and pressure.
When handling polypropylene machining, you’ll find two different types are available for use: Homopolymer or Copolymer. Although similar, each exhibits distinct differences in both appearance and performance. Homopolymer Polypropylene Homopolymer Polypropylene is the PP most commonly used. It has a high strength to weight ratio and is stiffer and stronger than Copolymer. It exhibits good chemical resistance and weldability, which allows this material to be used in many corrosion-resistant structures. Copolymer Polypropylene Copolymer Polypropylene material is softer than Homopolymer but has better impact strength, is tougher, more durable, and has better stress crack resistance and low-temperature toughness than Homopolymer.
