PP (Polypropylene) Overview

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.
