Products Description
Ultra-high molecular weight polyethylene (UHMWPE) plates are engineering plastic plates formed from ultra-high molecular weight polyethylene with an extremely high molecular weight (typically 1.Ultra-high molecular weight polyethylene (UHMWPE) plates are engineering plastic plates formed from ultra-high molecular weight polyethylene with extremely high molecular weight (typically 1.5 million to 10 million g/mol, more than ten times that of ordinary polyethylene) through molding, extrusion and other processes.5 million - 10 million g/mol, more than ten times that of ordinary polyethylene) through molding and extrusion processes.
The molecular chain length of this material far exceeds that of conventional plastics, creating a highly entangled microstructure that endows it with unique advantages such as super wear resistance, excellent impact resistance and self-lubrication, making it a "star material" in the industrial field that combines functionality and durability.

Core performance advantages
1.The wear resistance is the most prominent characteristic of UHMWPE plates.
Its wear resistance is 7 times that of carbon steel, 5 times that of stainless steel, and even higher than that of polytetrafluoroethylene (PTFE). The high-density molecular chains can form a stable transfer film during friction, reducing direct wear at the contact surface. This is particularly suitable for scenarios with high loads and long-term operation.
2. Excellent Impact Resistance - The "King of Resilience" that can withstand drops and impacts
Even at an extremely low temperature of -196℃, the UHMWPE plate can still maintain an extremely high impact resistance (notched impact strength > 100 kJ/m²), far exceeding that of polycarbonate and ABS materials, and it will not undergo brittle fracture. It can withstand severe impacts or vibrations.
3. Self-lubrication and low friction - The "sliding expert" that requires no maintenance
The friction coefficient is extremely low (static friction coefficient 0.07 - 0.11, dynamic friction coefficient 0.05 - 0.08), similar to that of PTFE, and it has self-lubricating properties. It can slide smoothly under dry friction conditions without the need for additional lubricating oil, significantly reducing energy consumption and noise.
4. Chemical stability and temperature resistance - Adaptability to complex environments
Except for highly oxidizing acids (such as concentrated nitric acid), it shows excellent tolerance to most acid-base salt solutions and organic solvents (such as hydrochloric acid, sodium hydroxide, ethanol). The operating temperature range is from -269℃ to 80℃ (the brittle point is as low as -196℃), and it is suitable for extremely cold or normal temperature environments.
5. Hygienic, non-toxic and lightweight - compatible across multiple fields
Complies with food-grade standards (FDA certified), odorless, does not adsorb impurities, and can be directly in contact with food; density is only 0.93-0.95 g/cm³ (lighter than water), combining the lightweight feature of plastics with the durability of metals.
Typical application scenarios
Industrial wear resistance: Mine conveyor chute liners (lifespan is 5-10 times that of steel plates), ore pipelines' inner linings in steel mills, vibrating screen screen plates;
Mechanical protection: Vehicle anti-collision guard plates (for mining vehicles/construction vehicles), port and dock anti-collision guardrails, gear/bearing substitutes;
Food and medical: Food processing conveying tracks (hygienic and non-toxic), surgical instrument anti-collision pads, clean container linings;
Special environments: Ocean vessels' cargo hold anti-slip liners (resistant to seawater corrosion), low-temperature laboratory workbench panels.
The ultra-high molecular weight polyethylene plate, with its comprehensive performance advantages such as "wear resistance, impact resistance, self-lubrication and corrosion resistance", has become an indispensable high-performance material in multiple fields including mining, chemical industry, machinery, and medicine. It is particularly suitable for scenarios with high requirements for lifespan, maintenance costs, and adaptability to extreme environments. It is the "all-rounder" among engineering plastics.
