Polyethylene (PE) Material Overview

Polyethylene is a lightweight thermoplastic valued for impact resistance, chemical resistance, low friction, and versatility. RapidDirect CNC machines HDPE, LDPE, and UPE / UHMW-PE, and injection molds HDPE and LDPE parts.

  • Lightweight and durable: PE delivers impact resistance and durability at a low weight.
  • Chemical resistance: Polyethylene resists many chemicals for industrial and consumer parts.
  • Low friction: PE's low-friction properties support sliding and moving components.
  • Two manufacturing options: Use CNC machining for custom geometry and injection molding for production parts.

Selection note: Choose HDPE for strength and impact resistance or LDPE for flexibility and toughness. Select CNC machining for custom geometry or injection molding for repeatable production parts.
