UHMWPE (Ultra-High Molecular Weight Polyethylene) is a versatile material—and its benefits shine brightest in UHMWPE hose applications. From low friction to extreme durability, UHMWPE’s traits make it a top choice for industries like food processing, chemicals, and heavy machinery. Below’s a breakdown of its core properties and how they enhance UHMWPE hose performance.
1.Extremely Low Friction Coefficient (Ideal for UHMWPE Hose Linings)
First, UHMWPE has an ultra-low static friction coefficient of just 0.07. It also has strong self-lubricating properties—no extra lubricants needed. This makes UHMWPE perfect for UHMWPE hose linings, as well as bearings, bushings, sliders, and equipment linings. For example, chemical UHMWPE hoses and food-grade UHMWPE hoses use UHMWPE linings to ensure smooth flow of liquids (no clogs or sticking).
When used as a friction part in equipment (or hose linings), UHMWPE boosts wear-resistant life.
It also cuts down on energy use—less friction means machines (and hoses) work more efficiently.
2. Exceptional Impact Resistance (Tough UHMWPE Hoses for Harsh Use)
Another standout property of UHMWPE is its unbeatable impact resistance—top among all plastics. Strong external impacts won’t crack UHMWPE, and neither will high internal pressure. To put it in perspective: its impact strength is 10 times that of nylon 66, 20 times that of PVC, and 8 times that of PTFE. Even in low temperatures, UHMWPE’s impact strength hits its peak. This flexibility is critical for UHMWPE hoses: it gives systems safe, reliable protection against sudden jolts or pressure spikes. Whether you’re using UHMWPE hoses in construction or manufacturing, they hold up to rough handling.
3. Long-Lasting Anti-Aging (Durable UHMWPE Hoses for Decades)
UHMWPE also has stable chemical properties and strong anti-aging capabilities. You can install UHMWPE hoses above ground or underground—either way, they last over 50 years. Per ASTM testing (with a 4.6kg/cm² load), UHMWPE’s heat distortion temperature is 85℃. But in real use, UHMWPE hoses work reliably at up to 90℃. In special cases, they handle even higher temperatures. UHMWPE also has excellent low-temperature toughness. At -269℃, it still keeps some ductility—no brittleness at all. This means UHMWPE hoses perform well in freezing environments, like cold storage or winter outdoor use.
