At Aetna Plastics, we provide top-tier materials to meet the needs of a variety of industries, from chemical processing and industrial manufacturing to medical and food applications. Polypropylene (PP) is one of the most widely used thermoplastics due to its lightweight nature, excellent chemical resistance, high impact strength, and versatility. Whether you need corrosion-resistant piping, durable industrial components, or FDA-approved food-grade materials, polypropylene is a cost-effective and high-performance solution.
What is Polypropylene?
Polypropylene (PP) is a semi-crystalline thermoplastic polymer known for its exceptional balance of chemical resistance, low moisture absorption, and mechanical strength. It is derived from polyolefins, making it a non-polar plastic with inherent resistance to many acids, bases, and solvents.
Types of Polypropylene:
Polypropylene is available in two primary forms, each with distinct advantages for different applications:
- Homopolymer Polypropylene (PPH)
- Stronger and more rigid than copolymer PP.
- Higher temperature resistance, making it ideal for industrial and structural applications.
- Commonly used in chemical processing tanks, piping systems, and automotive components.
- Copolymer Polypropylene (PPC)
- Slightly softer but offers better impact resistance, even at low temperatures.
- Greater flexibility compared to homopolymer PP.
- Often used for storage containers, food packaging, and medical components.
Both types of polypropylene are widely utilized in fabrication, welding, machining, and thermoforming, making them suitable for custom manufacturing solutions.
