The raw material used for manufacturing PU Seals is the polymer called polyurethane. The hardness of the piston seals is within the range of 75 to 94 shore A and the pressure is up to 300 bars. These hydraulic piston seals find application in mobile hydraulics, agricultural equipment, standard cylinders, injection molding machines and machine tools.
The features of these piston seals are:
High resistance to abrasion
Excellent Sealing function
Long working life in extreme conditions
Resistance against cold flow
