Polyurethane Elastomer ZU01 is an erosion resistant material that performs well in elastomer applications where ‘tramp’ is a problem. This is attributed to the high tear and tensile strength of ZU01.
It also has excellent resistance to oils and solvents, except ketones and esters. Polyurethanes are susceptible to hydrolysis attack in hot and/or acidic conditions over time.
General overview
Current elastomer parts available in ZU01 include the following
– Liners, 041, 018, 036, etc
–Impellers, and Throatbushes, available in all sizes.
