Abstract:

For chemical protective application, laminates of unlike rubbers may constitute structures with properties that are unavailable from either material alone. Laminates of ButylSilicone and of NitrileButyl were obtained by contract from a commercial firm. With 2-chloroethyl ethyl sulfide CEES as the permeant, the U.S. Army Research Laboratory, Materials Directorate ARL-MD determined the breakthrough times tb Of these laminates and of the individual rubber materials by means of the MIL-STD-282, Method 204, permeation test. To interpret the tb of the laminates in terms of tb of the single rubbers, a lag time model published in the literature was adopted. The resultant predicted values of tb for the laminates agreed fairly well with the experimental results obtained for these layered structures.
