Abstract
An elastomer blend is made by admixing fluoroelastomer and fluorinated silicone polymer (with optional filler and/or conductive particulate) into a polymeric admixture in weight ratios to provide a low vaporous hydrocarbon permeation rate and high thermal strain value in thermally robust elastomer cured from the blend. The blend is of especial use for making gaskets for use in high stress conditions at elevated operating temperatures.
