Articles, and particular telephone splices, are protectively encased in a material consisting of a low viscosity oil gelled by a block copolymer such as styrene-iosprene-styrene. Addition of polyethylene to the blend reduces the yield shear stress in the gelled compound and also advantageously supplies a desirable high temperature property of nonslump. Component ranges are described. Stratifying the compound within the closure so that the portion contacting splices is soft and plastic while the remainder is stiff and hard, meets a stringent encasement requirement while minimizing oil separation at high operating temperatures.
