- Resistance to Sea Water
This PU tube material is sea water resistance, making it ideal for marine seal components. It’s a top choice for offshore oil rig seals and coastal construction machinery seals, where saltwater corrosion often damages ordinary seal materials.
- Compatibility with HFA & HFB Fluids
The PU material stands out for its compatibility with HFA and HFB hydraulic fluids. This makes it safe for automotive seals and industrial automation seals industries where these fire-resistant fluids are widely used to ensure workplace safety.
- Resistance to Common Oils
It resists mineral oils, vegetable oils, and silicone oils effectively. This property makes it perfect for agricultural machinery seals (e.g., tractor hydraulic cylinder seals) and food-processing equipment seals (where vegetable oil-based lubricants are preferred).
- Stability with Biodegradable Oils
The PU tube material maintains stability against biodegradable hydraulic oils. It aligns with eco-friendly industrial trends, serving as a sustainable option for green-focused sectors like renewable energy equipment seals.
- Resistance to Ozone & Cold Oxygen
It also withstands ozone, ensuring long-term performance for outdoor seals like wind turbine hydraulic seals. Additionally, its cold oxygen resistance prevents brittleness, making it suitable for low-temp machinery seals (e.g., winter-use agricultural equipment seals).
