Abstract
Curable fluoroelastomers formed from the following fluoroelastomer mixtures: PA1 a) from 20 to 70% by weight of a fluorolastomer having the Mooney viscosity value, ML (1+10) at 121.degree. C., of greater than 60 points and containing from 0.01 to 3% by weight of iodine; PA1 b) from 0 to 70% by weight of a fluoroelastomer having the Mooney viscosity value, ML (1+10) at 121.degree. C., in the range of 20-60 points and containing from 0.2 to 5% by weight of iodine; PA1 c) from 5 to 60% by weight of a fluoroelastomer having the Mooney viscosity value, ML (1+10) at 121.degree. C., in the range of 1-20 points and containing an iodine percentage by weight greater than 0.3; said Mooney viscosity ML (1+10) at 121.degree. C. determined according to the ASTM D 1646 method; where said fluoroelastomers comprise monomeric units derived from a bis-olefin.
