Polyurethane timing Belts are highly flexible with longitudinal toughness to ensure perfect tooth meshing No dust-generation or flaking while running - clean Belt Homogeneous throughout its cross-section by virtue of thermoset moulding process Superior wear and abrasion resistance High resistance to oil, fat and grease Excellent resistance to ageing, hydrolysis, UV and ozone Low vibration and reduced noise level Good resistance to most acids and alkalis.
