High molecular weight polyethylene board is a heat-speed type engineering plastic board, and it is also the main product produced by our company. It can produce boards with a molecular weight of 3.5 million to 10.2 million. Its characteristics are:
1. The high molecular weight polyethylene board is damaged, and the larger the molecular weight, the higher the resistance and impact resistance of the material;
2. The impact strength of the high molecular weight polyethylene sheet is the value in the existing plastics, even at 70 ℃, there is still a very high impact strength;
3. Self-lubricating;
4. High molecular weight polyethylene board has low water absorption. Therefore, its physical and mechanical properties have nothing to do with the humidity factor in the working conditions used;
5. The high molecular weight polyethylene sheet is chemically stable, and can resist the corrosion of various corrosive media and solvents such as acid, alkali, salt and so on within a certain temperature and concentration range;
6. High molecular weight polyethylene board is tasteless, odorless, non-corrosive, and has physiological circulation and physiological adaptability.
7. Non-adhesive;
8. When the molecular weight of HDPE exceeds 500,000, the embrittlement temperature drops to 140℃. Even under the action of liquid nitrogen, the high molecular weight polyethylene can be used at a temperature below 269 °C, and still has a certain mechanical strength.
