G-ECOPUR is a casted hydrolysis-resistant polyurethane-elastomer (CPU) with similar properties to H-ECOPUR, especially regarding its chemical stability. G-ECOPUR can be used in the same hydraulic fluids as H-ECOPUR. Generally, G-ECOPUR is used for seals with a diameter from 540 mm up to 4000 mm as one piece and larger using our special welding technique.


G-ECOPUR 54D is a casted hard grade hydrolysis resistant polyurethane (CPU) most suitable for heavy duty large diameter applications. It has comparable chemical and mechanical properties to G-ECOPUR but with higher shore hardness and improved friction and wear characteristics.
