ASTM D1418 Designation: FKM
ASTM D2000/SAE Type, Class: HK
Apple Compound Designation: 32VT7EE
Standard Color: White
Description: Combining high temperature resistance with outstanding chemical resistance, Fluorocarbon-based compounds approach the ideal for a universal o-ring material.
Temperature Range: -13° to +446°F
Hardness (Shore A): 70
Features: High resistance to most chemicals used in cleaning medical products. No processing oil used so limits contamination from solvent extraction. Low outgassing due to post-curing process. No phthalates used in formula.
Testing: USP Class VI
Limitations: Fluorocarbons (Vitons) are not recommended for exposure to ketones, amines, low molecular weight esters and ethers. Steam sterilization can degrade surface of the compound.
