HPU Sealing Material
Enhanced Wear Resistance:
HPU seals offer superior resistance to wear and abrasion compared to standard polyurethane and other elastomeric materials. This makes them suitable for applications involving high dynamic loads and abrasive media.
High Tensile Strength:
The tensile strength of HPU is significantly higher than that of conventional polyurethanes. This property ensures that the seals maintain their integrity under high-stress conditions and do not easily tear or rupture.
Excellent Temperature Range:
HPU materials are capable of withstanding a broad temperature range, typically from -25°C to +150°C. Some formulations can endure even higher temperatures, making them versatile for different climatic and operational environments.
Superior Chemical Resistance:
These seals exhibit excellent resistance to oils, fuels, hydraulic fluids, water, and many other chemicals, minimizing the risk of swelling, cracking, or degradation when exposed to aggressive substances.
High Load-Bearing Capacity:
HPU can sustain high pressure without deforming, ensuring reliable sealing performance in hydraulic and pneumatic systems that operate under high-pressure conditions.
Flexibility and Elasticity:
Despite its strength, HPU maintains a degree of flexibility and elasticity, which is crucial for maintaining a seal under varying loads and during movement.
For seals in cylinders and valves where high pressure and variable temperatures are present.
Automotive Industry:
In the production of gaskets, O-rings, and other seals that require durability and resistance to automotive fluids.
Heavy Machinery:
Seals for construction and mining equipment that face abrasive conditions and require robust sealing solutions.
Oil and Gas Industry:
For components that need to withstand harsh chemicals and fluctuating pressures.
Food and Beverage Industry:
HPU seals can be formulated to comply with food-grade requirements while offering superior performance.
