What is the hardness of the black POM bar?

POM (Polyoxymethylene): English name Polyoxymethylene, commonly known as Saigang. POM plastic particles are extruded through an extruder at high temperature, and then extruded through corresponding die ports to obtain POM sheets and POM rods of different thicknesses and diameters. POM is a thermoplastic engineering plastic with high melting point and high crystallinity. Due to the good characteristics of POM, it is very suitable for machining on automatic lathes, and is especially suitable for manufacturing precision parts. POM is a linear polymer with no side chains, high density and high crystallinity, and has excellent comprehensive properties.
POM has good comprehensive properties. It is the hardest among thermoplastics. It is one of the plastic materials whose mechanical properties are closest to metal. Its tensile strength, bending strength, fatigue strength, wear resistance and electrical properties are all Very good, can be used for a long time between -40 degrees and 100 degrees.
The main characteristics of POM board:

High mechanical strength, high rigidity, high hardness, excellent elasticity, sliding and wear resistance, good creep resistance, even at low temperatures, high impact strength, very good dimensional stability, excellent mechanical properties, physiological inertness, Suitable for contact with food.
