As the development trend of ultra high molecular weight polyethylene---coal bunker lining board in chemical industry and its wide application:

1.The wear resistance of ultra-high molecular weight polyethylene bunker liner is the first in plastic,and the higher the molecular weight,the higher the wear resistance and impact resistance of the material;

2.The impact strength of the super high molecular weight polyethylene bunker liner is the highest value in the existing plastics,and it still has a high impact strength even at 70 degrees centigrade;

3,ultra-high molecular weight polyethylene liner lining,self lubrication performance is very good;

4,ultra-high molecular weight polyethylene bunker lining,low water absorption.Therefore,the physical and mechanical properties are independent of the humidity factors used in the working conditions;

5,ultra-high molecular weight polyethylene bunker liner chemical stability,in a certain temperature,concentration range,can be acid,alkali,salt and other corrosive media and organic solvents corrosion;

6、super high molecular weight polyethylene coal bunker lining,tasteless,non-toxic,odorless,itself non corrosive,with physiological,cyclical and physiological adaptability

7,super high molecular weight polyethylene liner non adhesion;

8.When the molecular weight of HDPE exceeds 1 million 500 thousand,the brittleness temperature decreases to 140.Ultra high molecular weight polyethylene can even be under liquid nitrogen,its use temperature of less than 269 degrees centigrade,there is still a certain mechanical strength
