Soft microcellular foams for cushioning, packaging. Semi-rigid foams for insulation, foam-in-place buoyancy. Hard microcellular foams for shoe soles, car bumpers, tyres, wheels, gears, fuel hose. Structural foam for housings, panels. Cast elastomers for bearings, gears and wheels.
NOTE: Polyether based PU is superior to Polyester-based PU in terms of resistance to hydrolysis, hysteresis, heat build-up and low temperature impact, but polyether PUs are inferior to Polyester PUs for oil and abrasion resistance, ageing and general mechanical props.
