PP (Polypropylene) in Injection Molding
Polypropylene (PP) is a lightweight thermoplastic valued for chemical resistance, toughness, and versatility. RapidDirect offers PP for CNC machining and injection molding, including custom prototypes, enclosures, housings, and functional parts.
- Lightweight: PP’s low density helps reduce part weight.
- Chemical resistance: PP resists many acids, bases, and solvents.
- Tough and flexible: PP supports components that need flex and durability.
- Versatile processing: PP is available for CNC machining and injection molding.
Selection note: PP combines low weight with resistance to many chemicals and repeated flexing. Select CNC machining or injection molding based on part geometry and production volume.
