Polyethylene (PE) is a type of polymers with strong chemical-resistance and wear-resistance. It is mainly divided into the low-density PE (LDPE) high-density PE (HDPE) and ultra-high molecular weight PE (UHMW-PE) The HDPE is the most massive among them. The UHMW-PE is an ultra-high-density Polyethylene whose average number of molecules is usually three millions. It has physical properties that are generally superior to those of the HDPE and this FDA-approved material is thus generally more expensive.
Characteristic
Impact Resistance
Lightweight
Food hygiene, Non-Toxic
Affordability
Low Temperature Durability (No change in properties at-50°
Wear Resistance, Chemical resistance (Resistant to acids and alkalis)
Welding capabilities
Low coefficient of friction, Non-absorption
▶ UHMW-PE
High-density polyethylene with a weight average molecular weight of about 3 million or more, which is similar to HDPE in its entirety. FDA-approved products with better mechanical properties
Applications
Storages of various chemical products lining suits and hoppers of various silos.
The highly slippery wear-resistant non-sticky shock-absorbent material can be used in various conveyor rollers liners guides and screws.
The material is also recommended for usage in medical and food processing fields because it is non-toxic and chemical-resistant.
