Polypropylene

Polypropylene, an economical and chemically resistant thermoplastic, boasts outstanding aesthetic attributes, making it a popular choice for a wide array of applications. Its low cost and durability contribute to its widespread usage across multiple industries.

Commonly utilized as a consumer packaging material, polypropylene offers excellent barrier properties and maintains its shape even under high temperatures. Additionally, the material's inherent flexibility and fatigue resistance render it suitable for manufacturing plastic hinges that require repeated motion. Polypropylene is also employed in waterproofing insulation due to its hydrophobic nature and resistance to moisture penetration.

FAQs About Polypropylene

General

Polypropylene, also known as PP, is a tough, rigid, and crystalline commodity thermoplastic. It is made from propene (or propylene) monomer. It a plastic with low density and high heat resistance. Its chemical formula is (C3H6)n. Polypropylene comes either as a homopolymer or as a copolymer and can be greatly boosted with additives.

Polypropylene Homopolymer

Homopolymer polypropylene contains only propylene monomer in a semi-crystalline solid form, It is a very durable, rigid plastic available in natural (a translucent white) and a variety of colors. It’s easily formed and widely used in orthotic and prosthetic applications.

Polypropylene Copolymer

Copolymer polypropylene is tougher and more durable than homopolymer polypropylene. Which tends to have better stress crack resistance than homopolymer polypropylene. It’s used in many of the same applications as homopolymer polypropylene.

YES, it is food safe. Polypropylene plastic used in food containers is FDA-compliant and will not leach harmful chemicals into the food or liquid they store.
