Product Description

Polyurethane is becoming a widely used sealing material due to its excellent abrasion resistance and extrusion resistance.
The most important characteristics of polyurethane materials are:
High tensile strength
Low compression set
Excellent cold flexibility
Constant shear modulus even at high temperatures
Weather and aging resistance
Superior damping properties
Low gas permeability
Good hydrolysis resistance
Outstanding tear strength and elongation
No impurities that interfere with paint coating

Polyurethane materials are resistant to:
Mineral oils and greases
Oxygen and ozone
Polyurethane materials are not suitable for use with:
Esters
Aromatic and chlorinated hydrocarbons
Concentrated acids and alkalis

H-PU Hydrolysis-resistant PU

H-PU maintains all the mechanicalproperties of standard PU while providingsuperlor water resistance, making it idealfor water-based applications like hydraulicpresses,tunnel boring machines, miningequipment, and press manufacturing FDA grades are available for use in food& beverage processing and medicalindustres
 

ADVANTAGE

Superior abrasion resistance enables it to withstand harsh, erosive conditions;
Outstanding extrusion resistance allows it to endure higher pressures and larger extrusion gaps;
Excellent mechanical strength enhances service life;
Low friction during startup reduces breakaway torque.

APPLICATION

Polyurethane O-rings are particularly suitable for applications where the O-ring is subjected to dynamic loads. These applications include hydraulic, pneumatic, and various other critical fields. In many cases, polyurethane O-rings are commonly used as replacements for nitrile rubber due to their excellent mechanical strength.

Thanks to their exceptional resistance to abrasion, polyurethane O-rings are more suitable than other materials for scenarios where holes must be traversed or frequently opened and closed, such as in plug connectors and couplings.

Our Advantages

High Quality

 

High-Quality Raw Materials. Our raw materials are sourced from top-tier suppliers in China, ensuring reliable quality that meets customers' usage requirements.Our PU made from MDI material featuring high strength, high toughness, and excellent chemical resistance.

Widely Used as Alternatives to International Brands. Our products serve as alternatives to globally renowned sealing brands such as Parker and Freudenberg .

Precision Turning Process. Utilizing turning manufacturing techniques, our products deliver high precision, low surface roughness, and superior sealing effectiveness.
Professionally certified through inspection procedures with SGS, ISO, and TÜV certifications.

 

Affordable prices,Cost-Effective

 

Raw Material Bulk Purchasing. Our large-scale and stable procurement volume provides better pricing for raw materials.

Rich Processing Experience. With 20 years of expertise focused on machined seal production, we achieve a high qualification rate and efficient material utilization, thereby enhancing cost-effectiveness.

Higher Customization Flexibility: Turned seals can be machined with greater adaptability to meet specific dimensional, geometric, and performance requirements.For non-standard sizes or special shapes, turning is more feasible, whereas moldedseals are constrained by fixed molds, making frequent modifications for custom needsdifficult.
Superior Dimensional Accuracy: Modern turning technology, supported by high-precision CNC machines, ensures tight tolerances and excellent surface finish, making itideal for applications demanding high sealing performance. In contrast, molded sealsmay suffer from dimensional variations due to mold wear, material shrinkage, and other process-related factors.
