HDPE Machining
Why Machining HDPE?
HDPE (High-Density Polyethylene) offers a unique combination of toughness, ease of machining, and environmental resistance. It performs well in demanding applications where metal and other plastics may fail.
- High Chemical Resistance: Handles acids, alkalis, solvents
- Low Water Absorption: Ideal for wet or humid environments
- Good Impact Strength: Withstands heavy loads and blows
- Lightweight & Tough: Excellent for large, durable parts
- Food-Safe: FDA compliant grades available
