A polyurethane roller is a roller made of polyurethane elastomer material. Polyurethane is a polymer material between plastic and rubber, with high elasticity, high strength, wear resistance and corrosion resistance.

Tungsten is a transition metal, but when it is combined with carbon to form tungsten carbide, its crystal structure is not magnetic. This means that pure tungsten carbide itself does not have any measurable magnetic properties. Therefore, industrial rollers using tungsten carbide coatings will not exhibit magnetism under normal conditions.

Tungsten carbide coating has relatively good thermal stability in high temperature environment. Generally, the heat resistance temperature of tungsten carbide can reach above 500°C. At this temperature, the structure of tungsten carbide coating will not change significantly, maintaining its mechanical properties and chemical stability.
