In the last piece we learned the material UHMWPE. It is one of the greatest new materials in modern industry. While it has been widely used in various products like chemical hose. Then this time, let me show you the great properties of UHMWPE hose.
Extremely low friction coefficient
The static friction coefficient is 0.07. Besides, it has good self-lubricating property. Thus it is an ideal material for bearing, bushing, slider and linings. That’s why chemical hose and food hose use it as lining. UHMWPE as the friction part of the equipment can improve the wear-resistant life. What’s more, it can achieve energy saving effects.
The impact resistance of UHMWPE ranks first among plastics. No matter strong external impact or high internal pressure can’t crack it. Its impact strength is 10 times that of nylon 66, 20 times of PVC and 8 times that of PTFE. In low temp condition, its impact strength reaches the highest value. Besides, the flexibility can provide extremely safe and reliable protection to the system.
UHMWPE has stable performance and good anti-aging ability. You can set it on the ground or underground. Then it will last more than 50 years. Measured according to the ASTM method (load 4.6kg/cm2), the heat distortion temp is 85℃. While the working temp can reach 90℃. In special cases, it can work at higher temp. Besides, UHMWPE has excellent toughness with good low temp resistance. It still has a certain degree of ductility at -269℃ without any signs of brittleness.
large volume resistance, breakdown voltage of 50KV/mm, and dielectric constant of 2.3. Within a wide temp and frequency range, it is suitable as a structural material in electric project.
Hygienic and non-toxic
UHMWPE is non-toxic, non-toxic and odorless. Besides, it is non-corrosive. Thus it is the great material for food grade hose.
