Daikin DAI-EL® G-801 Fluoroelastomer Terpolymer, 66% Fluorine Content
Categories: Polymer; Thermoset; Fluoropolymer, TS; Thermoset Fluoroelastomer; Rubber or Thermoset Elastomer (TSE)

Material Notes: DAI-EL® G-801 is a peroxide curable copolymer with medium Mooney viscosity suitable for transfer and compression molding. DAI-EL® G-801can be formulated with various peroxide cure systems to eliminate the need for post cure. DAI-EL® G-801 provides superior mechanical properties and resistance to steam and aqueous solvents compared with bisphenol cured fluoroelastomers. DAI-EL® G-801 may be used in compliance with 21 CFR 177.2600, Rubber articles intended for repeated use. Finished articles are required to comply with the end tests specified in 21 CFR 177.2600 (e) or (f), as applicable.

Typical Applications: O-Rings, gaskets, seals

Rheological Properties MDR 2000:
Temperature: 177°C
Frequency: 100 cpm
Strain: 0.5°
Test time: 6 min
