Daikin DAI-EL® G-7801 Fluoroelastomer Copolymer, Bisphenol Curable Grade, 66% Fluorine Content
Categories:	Polymer; Thermoset; Fluoropolymer, TS; Thermoset Fluoroelastomer; Rubber or Thermoset Elastomer (TSE)
Material Notes:	DAI-EL® G-7801 is a bisphenol cure-incorporated copolymer with high Mooney viscosity. It is designed especially for compression molding of O-rings, seals and other shapes. It has better mold flow and lower compression set than copolymers of similar Mooney viscosity. Typical Applications: O-rings, seals, gaskets, molded tubing Rheological Properties MDR 2000: Temperature: 177°C Frequency: 100 cpm Strain: 0.5° Test time: 6 min Rheological Properties ODR: Temperature: 177°C Frequency: 100 cpm Strain: 3 ° Test time: 12 min Information provided by Daikin.
