P4300 also has superior resilience/rebound characteristics compared to other available TPU materials.
The ability to rebound quickly is a major advantage in those sealing applications where there are likely to be severe shock loads and momentary pressure spikes.
The enhanced resilience/rebound characteristics of P4300 allow the sealing lips of a rod or piston sealing line of contact, and thereby allowing less fluid bypass.
Manufactured on a PPDI P4300 exhibits excellent physical; properties, unmatched when compared to any other polyurethane compound specifically formulated for fluid power service.
Because of the unique chemical nature of P4300, these excellent physical characteristics are maintained over board range of temperatures.
In short, P4300 offers many unique advantages and benefits over other conventional polyurethane seal elastomers.
Benefits of Parker P4300: Performs where other polyurethanes fail; Higher Temperature service; Resists extrusion over a board pressure range; High wear resistance for extruded seal life; Maintains sealing lip contact while reacting to rapid changes in pressure/load; Excellent resistance to compression set.
Recommended for piston seals, rod seals and wipers for all types of light, medium and heavy duty hydraulic cylinders, shock absorbers, off road, industrial and construction equipment.
P4300 is also available for pneumatic cylinder applications when long seal life is required.
