What is Polypropylene?
Polypropylene (PP) is a rigid and crystalline thermoplastic used widely in everyday objects like packaging trays, household products, battery cases, medical devices, etc.
Polypropylene Properties
There are two main types of Polypropylene: Homopolymer and Copolymer. Homopolymer is the most widely utilized general-purpose grade of Polypropylene. It contains only propylene monomer in a semi-crystalline solid form. Polypropylene copolymers are made of copolymers and block copolymers produced by polymerizing propylene and ethane. The melting point of Polypropylene is different for each of the main types, 160 – 165°C for Homopolymer and 135 – 159°C for Copolymer.
Polypropylene Strengths
Polypropylene is an excellent choice for lightweight applications. It is also very resistant to diluted and concentrated acids, alcohols, and bases, but it has limited resistance to aromatic and halogenated hydrocarbons and oxidizing agents. Food contact grades are available. Compatible with a wide range of fillers and additives to enhance physical properties.
Applications
Polypropylene is used in many industries from packaging to medical applications. Some of the most common applications you will find polypropylene are:
- Bottles
- Food Packaging
- Automotive
- Bumpers
- Fender Liners
- Industrial Equipment
- Rope and Twine
- Medical devices
- Acid and chemical tanks, sheets, pipes, etc.
