Daikin DAI-EL® G-952 Fluoroelastomer Terpolymer, 69% Fluorine Content
Categories:	Polymer; Thermoset; Fluoropolymer, TS; Thermoset Fluoroelastomer; Rubber or Thermoset Elastomer (TSE)
Material Notes:	DAI-EL® G-952 is a terpolymer suitable for various peroxide cure systems. DAI-EL® G-952 can be formulated to eliminate the post cure process. DAI-EL® G-952 is suitable for transfer and compression molding applications requiring excellent chemical and steam resistance. DAI-EL® G-952 has better low temperature resistance than high fluorine terpolymers such as G-901 and G-902. Typical Applications: O-Rings, gaskets, seals, tubing Rheological Properties MDR 2000: Temperature: 177°C Frequency: 100 cpm Strain: 0.5° Test time: 6 min Information provided by Daikin.
