Ultra High Molecular Weight Polyethylene refers to polyethylene whose &#; &#; molecular &#; &#; weight has been increased from the usual 20,000 to 300,000 to 1 to 7 million .
It is also sometimes called "UHMW-PE," "UHMW," "U-PE," or "UPE," which are the initials of its official name.
Ultra-high molecular weight polyethylene is a synthetic resin classified as a thermoplastic resin, and is one of the engineering plastics.
Because it has excellent abrasion resistance and lowest friction second only to fluororesin, it is used as a material for machine parts such as gears and guide rails, as well as hoppers.
Ultra-high molecular weight polyethylene has the following characteristics:
Its main features are its excellent lowest friction and abrasion resistance. It can be used for a long time in sliding applications because there is little risk of it being scratched or scraped.
It has extremely high impact resistance, exceeding that of polycarbonate (PC).
Its stable molecular structure also provides excellent chemical resistance, allowing it to be used in environments where liquids or chemicals are used.
Its water absorption rate is low at less than 0.01 %, making it an ideal material for areas where water is used.
The maximum operating temperature for ultra-high molecular weight polyethylene is generally 80°C, making it unsuitable for use in high temperature environments.
However, it can be used in low temperature environments down to -100°C.
Ultra-high molecular weight polyethylene has a large linear expansion coefficient, so it is not suitable for places where sudden temperature changes occur.
Because of its high self-lubrication, it is difficult to bond with dissimilar materials, so be careful when combining it with other parts or materials, as you will need to carefully consider the design beforehand.
Taking advantage of its excellent properties, ultra-high molecular weight polyethylene is used for a wide range of applications.
It is mainly used in applications where it has high wear resistance and self-lubrication.
