Product Overview
What are the advantages of polyurethane
1、 High temperature resistance Under high temperature conditions, polyurethane is still the first choice for high-pressure
hydraulic systems. The rated temperature of polyurethane is more than 120 ℃, and it can withstand 5000 psi or even higher pressure
at the same time. This extreme combination makes polyurethane a leader in similar products of hydraulic cylinders. Although
fluororubber can easily handle temperatures above 200 ℃, its pressure bearing capacity is poor, usually limited to 2000 psi or
even lower.

2、 High strength and toughness
Due to its good hardness and toughness, polyurethane seals have excellent extrusion resistance. In addition, excellent hydraulic seals must be resistant to shearing and tearing. Under the action of pressure, hydraulic oil can easily break through the defense line of inferior seals. Polyurethane will deform under pressure to adapt to the change of clearance, thus ensuring reliable sealing; When the pressure is removed, its high strength characteristics can restore it to its original shape instead of producing permanent deformation.

3、 High wear resistance
Fluid contamination is a common symptom of hydraulic systems. When particles erode the seals, there is a risk of premature seal failure. However, polyurethane benefits from its natural high wear resistance, which is much better than other polymers such as nitrile rubber and fluororubber.
