Trelleborg Sealing Solutions has developed a proprietary polyurethane compound called Zurcon® Z25. It demonstrates all the excellent characteristics of industry-leading Zurcon® grade Z20 with an elevated operating temperature up to +130° C/+270° F.
Zurcon® Z25 Polyurethane Material
Improved extrusion resistance and compression set
Zurcon® Z25 is recommended for all hydraulic applications where high temperature performance is required due to its improved extrusion resistance and compression set. The material is ideal for use in heavy duty cylinder sealing applications where it can guarantee a long service life. These include industrial and mobile applications with limited cooling systems or cylinders exposed to high-temperature painting processes.
"Zurcon® Z25 is a significant advancement in the field of polyurethane sealing technology," says Joe Woods, Fluid Power Segment Manager for Trelleborg Sealing Solutions Americas. "It is able to perform at much higher temperatures than traditional polyurethane materials, allowing for the production of high-performance seals that can be commercially and technically competitive. This translates to better equipment performance for our customers."
Ideal for rotary applications
Self-energizing, Zurcon® Z25 operates at pressures up to 40MPa/5,800psi without a Back-up Ring. It is suitable for use in all hydraulic fluids and has a low compression set. It has an MDI (diphenylmethane diisocyanate) material base and is also suitable for rotary applications such as swivel joints, where heat is generated by high pressures and low speeds.
