High impact resistance black uhmw sheet
Black uhmw sheet is an engineering plastic with superior properties, such as abrasion resistance, impact resistance, very low friction coefficient, good self-lubricating properties, excellent low temperature resistance, chemical resistance, etc.
1.Improve wear resistance of black uhmw sheet
One of the most striking properties of high molecular weight polyethylene is its extremely high abrasion resistance, which is invaluable in many engineering applications. Among all the current plastics, its abrasion resistance is first.
2.High impact resistance of black uhmw sheet
The impact strength of ultra-high molecular weight polyethylene is related to its molecular weight. This is because the molecular chain hinders its photo-crystallization effect, so that there are large amorphous regions in the macromolecules, so it can absorb large impact energy.
The impact resistance of ultra-high molecular weight polyethylene at room temperature can be divided into polycarbonates known for their impact resistance. They are used in common engineering plastics. Ultra high molecular weight polyethylene has strong impact resistance even at a low temperature of -40 degrees. Even at a liquid-gas temperature of -269 degrees, it can still maintain good impact resistance. This excellent low temperature characteristic makes The application of UHMWPE is extended to the field of low temperature engineering.
3.Very low friction coefficient
The ultra-high molecular weight polyethylene plate is very wear-resistant, and has a low friction coefficient and good self-lubrication. It is an ideal bearing sleeve, slider, and lining material.
Using ultra-high molecular weight polyethylene as the friction part of the equipment, in addition to improving the wear life, it can also save energy.
4.Good chemical resistance
Ultra high molecular weight polyethylene sheet has good chemical resistance. Except concentrated nitric acid and concentrated sulfuric acid, it will not be corroded in all alkali and acid solutions, and can be used in concentrated hydrochloric acid at a temperature of 80 degrees It is also stable in <20% nitric acid and <75% sulfuric acid, and it is also very stable to water and liquid washing.
However, ultra-high molecular weight polyethylene is extremely swellable in aromatic or halogenated compounds, so special attention should be paid to its application.
