Ultra-high molecular weight polyethylene fender veneer pe fender veneer polyethylene board

Ultra-high molecular weight polyethylene fender veneer Low temperature impact resistant HMWPE fender

What is UHMWPE fender veneer pads?

UHMWPE fender has light weight, impact resistance, wear resistance, corrosion resistance, UV resistance, aging resistance, small friction coefficient, and can effectively prevent ultraviolet radiation. Its impact strength is 20 times that of polyvinyl chloride, 10 times that of nylon 66, and 8 times that of polytetrafluoroethylene. Low reaction force, small surface pressure, reasonable energy absorption; strong adaptability to constant and pitching of ships when berthing; easy installation and maintenance.

Ultra-high molecular weight polyethylene (UHMWPE) properties:

wear resistance:

The wear resistance of UHMWPE is the crown of plastics, and surpasses some metals. Compared with other engineering plastics, the mortar wear index of UHMWPE is only 1/5 of PA66, and 1/10 of HEPE and PVC; compared with metals, it is 1/7 of carbon steel, 1/27 of brass. Such high wear resistance makes it difficult to test the degree of wear resistance with the general plastic wear test method, so a mortar wear test device is specially designed. The wear resistance of UHMWPE is directly proportional to the molecular weight, the higher the molecular weight, the better the wear resistance.

   Impact resistance:

The impact strength of UHMWPE ranks among the best among all engineering plastics. The impact strength of UHMWPE is about 2 times that of impact-resistant PC, 5 times that of ABS, and more than 10 times that of POM and PBTP. The impact resistance is so high that it is difficult to break it by the usual impact test method. Its impact strength increases with the increase of molecular weight, reaches the maximum value when the molecular weight is 1.5 million, and then gradually decreases as the molecular weight continues to increase. It is worth pointing out that it can also maintain excellent impact strength in liquid nitrogen (-195°C), which is not found in other plastics. In addition, it has a higher hardness on the compound impact surface.


UHMWPE has a very low friction coefficient (0.05-0.11), so it has excellent self-lubricating properties. The dynamic friction coefficient of UHMWPE is 1/2 of that of PA66 and POM under the condition of water lubrication, and it is second only to polytetrafluoroethylene (PTFE) under the condition of no lubrication; The lubricity after lubricating oil is even better. Therefore, in the field of tribology, UHMWPE is known as a friction material with very ideal cost/performance.

1) Impact energy absorption

UHMWPE has excellent impact energy absorption, and the impact energy absorption value is among the best among all plastics, so the noise damping performance is very good, and it has excellent sound reduction effect.

2) Low temperature resistance

UHMWPE has excellent low temperature resistance and is still ductile at the temperature of liquid helium (-269°C), so it can be used as low temperature resistant components in the nuclear industry.

3) Hygienic and non-toxic

UHMWPE is hygienic and non-toxic, and can be used in contact with food and medicine.

4) Non-sticky

The surface adsorption ability of UHMWPE is very weak, and its anti-sticking ability is second only to PTFE, so the surface of the product is not easy to stick to other materials.

5) Small water absorption

The water absorption rate of UHMWPE is very low; generally less than 0.01%, only 1% of PA66, so it is generally not necessary to dry before molding.

6) Tensile strength

Because UHMWPE has the necessary structural characteristics toward stretch orientation, it has ultra-high tensile strength, so it can be used to prepare fibers with ultra-high elastic modulus and strength by gel spinning, and its tensile strength is as high as 3-3.5GPa , The tensile elastic modulus is as high as 100-125GPa; the fiber specific strength is in the forefront of all fibers that have been commercialized so far, 4 times larger than carbon fiber, 10 times larger than steel wire, and 50% larger than aramid fiber.

7) Aging resistance

Ultra-high molecular weight polyethylene (UHMW-PE) has good aging resistance, longer service life and cost savings

Hot Products

It have excellent wear resistance, low temperature impact resistance, selflubricating, nontoxic, water resistance, chemical resistance, and heat resistant, they are superior to general PE. It can be widely used to impact resistance, wearresistant, corrosionresistant, nonsticking, reduce noise, and high hygiene requirements of industrial mining field. It can greatly reduce operatingcosts of the equipment and maintenance, at the same time improve overall economic benefits.
