PU O-Rings Polyurethane materials are becoming more and more common as rubber seals because of their excellent resistance to abrasion and extrusion.


PU O-ring seals and other styrene-butadiene rubber comparison, the specific advantages of the choice of pc polycarbonate production manufacturing O-ring is due to this type of raw material has the following obvious physical properties: polyurethane material O-ring seals ring - very strong abrasion resistance, applicable to the corrosive office environment; polyurethane material O-ring - resistance to extrusion work ability, can bear high pressure and expand the extrusion gap; - excellent Physical properties, long service life; PU polyurethane material O-ring - small friction, reducing the running force. Imported polyurethane O-rings


hydraulic presses, pneumatic and other major equipment. In many cases, polyurethane materials have replaced nitrile plastics in condition because of their high impact toughness.
Polyurethane O-rings are more suitable than sealing rings made of other materials for applications where holes must be spanned or must be opened and closed frequently, such as tight connectors and plug connectors, because they are particularly resistant to abrasion.
Polyurethane O-rings are particularly central to the sealing of pneumatic seals and system software because of their low reduction of permanent deformation and low friction.
