Carlock Sealing's standard green PU (Polyurethane) is specifically formulated for heavy-duty sealing applications that demand maximum abrasion resistance. This high-elasticity elastomer combines the toughness of plastic with the flexibility of rubber. Precision-machined by Carlock Sealing, our green PU seals excel in high-pressure hydraulic systems, providing a reliable barrier against leaks even in environments with abrasive particles.
- Exceptional Abrasion Resistance: Outperforms standard rubbers (like NBR) by 5-10 times in wear-intensive applications.
- High Tensile & Tear Strength: Resists extrusion and damage even under extreme hydraulic pressure peaks.
- Superior Elastic Memory: Quickly recovers its shape after deformation, ensuring long-term sealing contact.
- Excellent Oil & Chemical Resistance: Highly compatible with mineral-based hydraulic oils, greases, and aliphatic hydrocarbons.
Technical Disclaimer: While green PU offers industry-leading wear resistance, its performance can be affected by temperatures exceeding 100°C or exposure to concentrated acids and hot water. Carlock Sealing recommends a thorough review of your operating media before selection.
FAQ:
Q: Why is this PU material green?
A: The green color is an industry-standard indicator for high-performance, wear-resistant polyurethane grades used in Carlock Sealing's CNC machining process, often used to distinguish it from softer or hydrolysis-sensitive grades.
Q: Can Carlock Sealing's green PU handle water-based fluids?
A: Standard green PU is optimized for oil-based hydraulics. For water-based fluids or high humidity, Carlock Sealing recommends our H-PU (Hydrolysis-resistant Polyurethane) range.
Q: Is there a mold fee for custom PU U-cups or wipers?
A: No. At Carlock Sealing, we use advanced CNC turning technology to manufacture custom seals directly from semi-finished tubes, eliminating all mold costs and shortening lead times.
