Investigative Study on the Feasibility of Utilizing Fluorinated Ethylene Propylene Elastomers as Protective Mask Faceblank Materials.

Abstract

This paper demonstrates the feasibility of obtaining a tough, transparent crosslinked fluorocarbon elastomer with reduced creep. The linear material exhibits creep and tackiness but is relatively clear. Existing vulcanizing recipes yield opaque, crosslinked materials. Polymerization is accomplished via high energy radiation. The linear fluorocarbon is physically bound up with the crosslinked network formed by the polymerized monomer, producing a semiinterpenetrating polymer network (IPN) of the second kind. The optimum conditions for the synthesis of a fluorocarbon elastomer with the desired properties, appear to be a dose level of 5.0 to 7.5 Mrads of beta radiation and a trimethylolpropane trimethacrylate (TMPTM concentration of 3-5%, based on experiment.
