HOVOO PU O-ring
It is mainly used for static or dynamic sealing to prevent liquid or gas leakage
1. Characteristics of PU material
Wear resistance: Polyurethane is one of the known resistant elastomers and is particularly suitable for sealing scenarios with high friction, high pressure or frequent movement.
2.Oil resistance: Good resistance to mineral oil, hydraulic oil, lubricating oil, etc., better than ordinary rubber (such as NBR).
High mechanical strength: strong resistance to tear and compression deformation, suitable for high-pressure environments (such as hydraulic systems).
3.Elasticity and resilience: Dynamic sealing performance is excellent, suitable for reciprocating or rotary sealing.
4.Low temperature resistance: Some PU materials can maintain elasticity at -40°C, but the high temperature resistance is weak (the general upper limit is 80-100°C, and special modified materials can reach 120°C).
| Temperature range: | -40 ° C to + 100 ° C |
| Pressure range | no ring static seal application ≤500 Bar |
| Running speed | reciprocating application ≤1m/s |
| Hardness | 93 +2 Shore A |
