Ultra-high molecular weight polyethylene powder and ultra-high molecular weight polyethylene fiber

摘要

The present invention provides an ultra-high molecular weight polyethylene powder having a viscosity-average molecular weight of 10×10⁴ or higher and 1000×10⁴ or lower, wherein a difference between a temperature at which a torque value reaches 80% of the maximum torque value and a temperature at which the torque value reaches 20% of the maximum torque value is 0.1° C. or more and 50° C. or less in torque value measurement.
