The advantage of uhmwpe/hdpe liner
The wear resistance of UHMWPE ranks first in plastic, and exceeds that of certain metals.
Mortar wear index
2. Impact resistance
The impact strength of UHMWPE at the top of all engineering plastic.
UHMWPE has a very low coefficient of friction(0.05-0.11),so that it has a very good self-lubrication.
4. Corrosion resistance
UHMWPE has excellent resistance to chemicals,in addition to the strong oxidizing acid,in a certain temperature and the concentration range of competence of various corrosive medium (acid,alkali,salt) and various organic media.
5. Absorb impact energy
UHMWPE has excellent shock absorption,impact energy absorption value is the highest in all plastic,and it has a excellent effect of the silencer.
6. Low temperature resistance
UHMWPE has excellent low temperature resistance,and can be used as a low temperature component in the nuclear industry because of its still have the ductility at low temperature (-269℃).
7. Not easy adhesion
UHMWPE surface adsorption force is very weak, its ability to resist adhesion to the plastic is next only to the best PTFE, so the surface of the product and other materials are not easy to stick.
8. Hydrophobic property
UHMWPE water absorption rate is very low, generally less than 0.01%, only 1% of PA6, and therefore do not need to dry before processing.
9. Tensile strength
As the UHMWPE has the necessary structural characteristics of the super tension orientation, so there is no comparable ultra-high tensile strength, its tensile strength up to 3 - 3.5GPa.
