Abstract
After storage period of 1.5 years,then 0,5,10,20 days and 60 days hygrothermal test were carried out for nitrile rubber,fluororubber and fluorosilicone rubber,the appearance,mass gain,Shore A hardness,tensile strength,elongation at break and set after break were investigated in the dry and wet conditions.The results show that different samples had distinct moisture absorbing performance.After storage and hygrothermal environment,the nitrile rubber less affected; the fluororubber absorbed a amount of moisture,but did not produce significant effects of aging on the hardness and the mechanical properties; the fluorosilicone rubber significant aged after the storage,and hygrothermal environment speeded up the aging process.The nitrile rubber and fluororubber suitable for storage in the hygrothermal environment.关键词
