Ultra-high molecular weight polyethylene (UHMW-PE) is a new kind of engineering thermoplastics with more than 3 million viscosity-average molecular weight.
For Polyethylene molecular weight classification the following guidelines can be used:
• HDPE (High Density Polyethylene): 100,000 – 400,000 MW
• HMWHDPE (High Molecular Weight High Density Polyethylene) 500,000 – 1,999,999
• VHMWHDPE (Very High Molecular Weight High Density Polyethylene) 2,000,000 – 3,100,000
• UHMWPE (Ultra High Molecular Weight Polyethylene) > 3,100,000 + MW
