Polyurethane roller

Polyurethane roller is an industrial roller component with a metal roller core as the base and聚氨酯 elastomer coating on the surface, combining high strength and high elasticity, widely used in printing, textile, metallurgy, and other fields. Its core characteristics include:

‌       1. Outstanding Physical Properties: Wide hardness range (Shore A50-D80), rebound rate ≥95%, tear strength up to 30-60 kN/m, wear resistance 3-5 times that of rubber.

       2. Strong chemical stability: Resistant to oils and solvents (such as diesel, lubricants, UV inks), but sensitive to strong acids and bases.

       3. High environmental adaptability: Tolerates temperature ranges from -40℃ to 120℃, maintaining dimensional stability in extreme environments such as humid and dry conditions.

‌       4. Multi-functional Applications: Used in the printing industry for ink transfer/paper pressing, in the textile field for guiding fabric/dyeing, and in metallurgy for high-temperature plate material conveyance and cleaning. Material formulations such as polyester and polyether can be adjusted to meet various operational requirements.
