HDPE and UHMWPE, though similar sounding plastics, have distinct applications due to slight differences in their molecular structure. Here's a breakdown:
HDPE (High-Density Polyethylene):
- Strengths: Affordable, lightweight, good chemical resistance, easy to machine and fabricate.
- Applications: Commonly used for:
- Bottles (milk jugs, shampoo bottles)
- Food containers
- Grocery bags
- Pipes and tubing
- Chemical storage tanks
- Cutting boards (lower-end)
- Toys
UHMWPE (Ultra High Molecular Weight Polyethylene):
- Strengths: Exceptional wear resistance, high impact strength, low friction coefficient, good chemical resistance.
- Applications: Used in demanding environments for:
- Wear pads and liners (conveyor belts, chutes)
- Gears and bearings
- Artificial joints (hip replacements)
- Marine components (boat fenders)
- Cutting boards (high-end, butcher block)
- Bulletproof vests (backing material)
