Fluoroelastomer admixture, it is respectively 3 it includes number-average molecular weight Mn (liquid chromatography, developing solvent tetrahydrofuran, 0.5 weight % of polymer concentration, 35 DEG C of measuring temperature), 000,000 or more 5~60 weight % of high molecular weight fluoroelastomer, 100,000~1,000,000 middle-molecular-weihydroxyethyl fluoroelastomer 20~80 weight % and 7,000~13,000 10~50 weight % of low molecular weight fluoroelastomer.The fluoroelastomer admixture realizes soft and low modular ratio while improving roller processability. |
