Chemical Resistance | PORON Urethanes are unaffected by mild organic acids and bases. They show modest swelling with oils and greases and other linear hydrocarbons. Strongly polar solvents will greatly swell PORON Urethanes. In most cases, physical properties recover to a great extent as the solvents evaporate. |
Additional Solvent Resistance 8Soap and Water 50/50) | No tackiness or surface deterioration |
