polyurethane oring/polyurethane o-ring/polyurethane o ring

Polyurethanes are widely used in high resiliency flexible foam seating, rigid

foam insulation panels, microcellular foam seals and gaskets, durable elastomeric

wheels and tires, automotive suspension bushings, electrical potting compounds,

high performance adhesives and sealants, Spandex fibers, seals, gaskets, carpet

underlay, and hard plastic parts. We can produce the PU o ring size for standard

and custom,A polyurethane, commonly abbreviated PU, is any polymer consisting

of a chain of organic units joined by urethane (carbamate) links. Polyurethane

polymers are formed through step-growth polymerization by reacting a monomer

containing at least two isocyanate functional groups with another monomer containing

at least two hydroxyl (alcohol) groups in the presence of a catalyst.
