LDPE in CNC Machining
Low-density polyethylene (LDPE) is a flexible, lightweight thermoplastic with chemical resistance and low moisture absorption. Its flexibility and toughness suit custom parts for packaging, automotive, and consumer products.
- Flexible and tough: LDPE suits components that need to bend or absorb impact.
- Chemical resistance: The material resists acids, bases, and many common chemicals.
- Low moisture absorption: LDPE performs well in humid environments.
Selection note: Choose LDPE for lightweight parts that need flexibility, toughness, and chemical resistance. CNC machining supports custom geometry, while injection molding produces repeatable parts.
