Polypropylene (PP) Machined Parts
A Guide to Polypropylene - CNC Milled & Turned Parts: Properties, Applications and Design Considerations
What is Polypropylene?
Polypropylene (PP) also known as polypropene is a hydrocarbon polymer and is one of the most commonly produced plastics in the world.
It is sometimes referred to as the ‘steel of the plastic industry’ due to its adaptability.
PP is a thermoplastic that is available as a Copolymer and Homopolymer. It is commonly used for mechanical components in corrosive environments.
