Overview
HMWPE (High Molecular Weight Polyethylene), also referred to as PE500, is an engineering-grade polyethylene offering improved impact resistance over PE300. With better wear and abrasion performance, it is particularly suitable for high-impact, dynamic applications such as conveying and marine systems. It maintains its mechanical properties in damp and wet environments and provides excellent chemical resistance, making it versatile for industrial and food-related applications. Its low moisture absorption and smooth surface also support hygienic use and ease of cleaning.
Key Features
- Higher impact resistance than PE300
- Tough and flexible under load
- Excellent chemical and corrosion resistance
- Low moisture absorption
- Good wear and sliding properties
- Easy to machine and fabricate
- FDA and EEC food contact compliant (natural)
- Lightweight with good energy absorption
Applications
- Conveyor components and guide rails
- Liners for chutes, hoppers and bins
- Marine fenders and dock bumpers
- Cutting surfaces and protective pads
- Food processing and packaging equipment
- Transport trays and work surfaces
- Wear blocks and mechanical shims
Weaknesses
- Lower abrasion resistance than PE1000 (UHMWPE)
- Low stiffness compared to filled engineering plastics
- Difficult to bond or glue (requires welding or mechanical fastening)
