Port terminal shield UHMWPE fender veneer panel Anti-collision wear-resistant plate

Performance introduction of UHMWPE fender veneer PE fender pads :

1. High wear resistance: Among all the current engineering plastics, the high molecular weight polyethylene liner has the best wear resistance and is the most eye-catching. The higher the molecular weight, the more wear-resistant the material is, even more than many metal materials (such as carbon steel, stainless steel, bronze, etc.). For example, the service life of UHMW-PE pipe is 4-6 times that of steel pipe under strong corrosion and high wear conditions, and the transmission efficiency is increased by 20%. It fully demonstrates the advantages of "energy saving, environmental protection, economy and high efficiency".

2. Corrosion resistance: It is not corroded in lye, can be used in concentrated hydrochloric acid at 80°C, and has stable performance in 75% concentrated sulfuric acid and 20% nitric acid. It is also very stable to seawater and liquid detergents.

3. Low coefficient of friction: The coefficient of static friction is 0.07, with good self-lubricating properties. It is an ideal material for bearings, bushings, sliders, and linings. Using UHMW-PE as the friction part of the equipment can not only improve the wear life, but also save energy.

4. Impact resistance: The impact resistance ranks first among plastics, and it is difficult to make it crack whether it is a strong external impact or internal pressure fluctuations. Its impact strength is 10 times that of nylon 66, 20 times that of polyvinyl chloride, and 8 times that of polytetrafluoroethylene; especially in low temperature environments, its impact strength reaches the highest value, and its flexibility provides extremely safe and reliable transportation systems. protection.

5. Aging resistance: stable performance, can be buried on the ground or underground, and will not age for 50 years. Measured according to the ASTM method (load 4.6kg/cm2), the heat distortion temperature is 85°C, and the service temperature can reach 90°C. In special cases, it is allowed to be used at a higher temperature. UHMW-PE is a material with excellent toughness, and its low temperature resistance is also very good. At a low temperature of -269 ° C, it still has a certain degree of ductility without signs of embrittlement. However, the coefficient of linear expansion is large and the thermal conductivity is poor, so full attention should be paid when designing products.

6. Electrical properties: large volume resistance, breakdown voltage up to 50KV/mm, dielectric constant 2.3. In a wide temperature and frequency range, it is suitable as a structural material for electrical engineering.

7. Hygienic and non-toxic: UHMW-PE is tasteless, non-toxic, odorless, non-corrosive in itself, and has physiological inertia and physiological adaptability. The US Food and Drug Administration (FDA) and the US Department of Agriculture (USDA) allow it to be used in contact with food and drugs. High molecular weight polyethylene board has many excellent properties.

As a wharf fender, ultra-high molecular weight polyethylene fender board can prevent damage caused by the collision between ships and wharves. It has good impact resistance and replaces traditional steel fenders. It is widely used in major ports and wharves.

Cold resistance:

When the molecular weight of high-density polyethylene exceeds 500,000, the embrittlement temperature drops to -140°C. And ultra-high molecular weight polyethylene (1.5 million-7.2 million molecular weight) can even work under liquid nitrogen or liquid helium, and its service temperature can reach -269°C, and it still has certain mechanical strength. So that it will not crack when soaked in seawater all the year round.

Water absorption:

The water absorption rate of ultra-high molecular weight polyethylene board is extremely low (<0.01%), and its physical and mechanical properties have nothing to do with the temperature factor in the working conditions of use.

Excellent chemical resistance:

Ultra-high molecular weight polyethylene has high chemical stability, and can resist the action of various corrosive media (acid, alkali, salt) and organic solvents such as acid, alkali, and salt within a certain temperature and concentration range.

It has excellent high impact resistance, good toughness, and good environmental stress crack resistance.

Anti-ultraviolet, long service life.

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.
HDPE Sheet is a semi-crystalline, thermoplastic engineering material with high toughness and good low-temperature properties. Customization is available for different specifications and performances to serve different applications.
We can make different UHMWPE Sheet according to different application .Like anti-UV resistant anti-static and with other characters , Best quality with good surface and color make our UHMWPE sheet more and more popular all over the world.
Uhmwpe marine dock bumper pad could avoid the impact damage between ships and dock . Because of the pe plastic marine fender face pad fender high impact resistance performance, HDPE / UHMWPE marine dock bumper pads instead of the traditional steel ones is widely used in ports and docks at home and abroad.
Langrui engineered plastic cribbing plates and outrigger pads are lightweight, strong, and solid designed tu support your crane, and can be easily handled and positioned byp one persn or two. It can not be warped like wood or corroded like steel. It won't break in the long guaranteed time and obviously could not attract thieves.
