Polyurethane Prepolymer for Mining Screen Panels and Wear Liners

Polyurethane Prepolymer for Mining Screen Panels and Wear Liners. Lasts 3 to 5 times longer than conventional rubbers and outwears many metals in gritty, high friction environments. Liquid casting ensures zero joints in large parts, allows for complex geometries, and supports metal/plastic inserts. Wide selection of MDI/TDI systems with Polyester backbones to match specific hardness (Shore A 80 to D75) and color requirements. Excellent resistance to oil, grease, and solvents (Ester-based); superior hydrolysis and microbial resistance (Ether-based). Optimized synthesis process ensures low free TDI/MDI levels, meeting strict international safety and environmental standards. Maintains dimensional stability under extreme pressure without plastic deformation ideal for heavy-duty rollers and wheels. Features controlled reactivity, long pot life, and good flowability, reducing production defects and improving mold release. Extended service life and minimal maintenance significantly cut downtime and replacement costs for end-users.
