Cancarb Limited Releases new Tech Study on Continuous Compressive Stress Relaxation (CCSR) in FKM Compounds

June 21, 2019 - Cancarb is happy to announce the release of our newest technical study. Continuous Compression Set Relaxation (CCSR) is a new, innovative test to demonstrate the sealing capabilities of rubber in real-world environments. In this study, we have evaluated the replacement of N774 with Thermax® N990 in FKM rubber, factoring in the impact of today's smaller displacement, hotter running engines. This includes an evaluation in the more chemically aggressive, low viscosity oils now being used. Physical and rheological testing of aged specimens was completed.
