PP Random Copolymer (PPR) is a type of polypropylene copolymer that contains a small amount of ethylene monomer (usually less than 7%) which is randomly distributed within the polypropylene chain. The incorporation of ethylene in the polymer structure enhances the flexibility, impact resistance, and transparency of the polymer, making it suitable for use in a wide range of applications. PPR is widely used in the production of packaging films, injection-molded parts, blow-molded bottles, pipes, and other products that require good clarity, toughness, and chemical resistance. PPR is also known for its excellent sealing properties, which make it a popular choice for food packaging and medical applications.
Product Types:
PP Random Copolymer (PPR) is a type of polypropylene that has random co-monomer units of ethylene incorporated into the polymer chain. This results in improved impact resistance and better high-temperature performance compared to polypropylene homopolymer.
PPR has several applications, including:
Hot and cold water supply pipes: PPR pipes are used in plumbing systems for hot and cold water supply due to their excellent chemical resistance, low thermal conductivity, and long-term durability.
Heating systems: PPR is also used in heating systems due to its ability to withstand high temperatures and pressure.
Food packaging: PPR is used in food packaging due to its good barrier properties and ability to withstand sterilization processes.
Automotive parts: PPR is used in various automotive parts such as door panels, interior trims, and bumpers due to its good impact resistance and lightweight properties.
Household items: PPR is used in various household items such as storage containers, toys, and furniture due to its good mechanical properties and ease of processing.
