Diffusion in ethylene–propylene rubber
Journal of Polymer Science Part A-1: Polymer Chemistry, 1967AbstractA study of sorption in a copolymer of ethylene and propylene is presented. Long‐time sorption and desorption measurements provided the actual diffusion coefficient in the limit of zero concentration gradient. An analysis of the diffusion–sorption data reinforced the Frisch hypothesis about diffusion in a polymer matrix.

Nanoclay is used to enhance the mechanical properties of ethylene-propylene-diene rubber (EPDM)/styrene-butadiene rubber (SBR) blends. Sulphur (S), dicumyl peroxide (P), and mixed systems (S + P) were used as crosslinking or vulcanizing agents for the ...

Sulfur Vulcanizable Ethylene-Propylene Rubbers
Rubber Chemistry and Technology, 1963Abstract Our research directed to obtaining new rubbers based on the copolymerization of ethylene with propylene started some years ago. We soon succeeded in establishing that it was possible to prepare copolymers of these two monomers showing interesting elastomeric properties.

Degradation of flame‐retardant ethylene‐propylene‐diene rubber by radiation and steam
IEEJ TRANSACTIONS ON ELECTRICAL AND ELECTRONIC ENGINEERING, 2020Safety‐related cables in nuclear power plants must be functional even during the occurrence of a severe accident. In this regard, flame‐retardant ethylene‐propylene‐diene rubber (FR‐EPR) widely used for electrical insulation in safety‐related cables was ...

Ethylene-propylene rubber—EPM and/or EPDM—was first introduced in the United States in limited commercial quantities in 1962. Though commercial production began only in 1963, EPM/EPDM rubber is now the fastest growing elastomer (ca. 6% per year), and there are presently five manufacturers in the United States, four in Europe, and three in Japan.

D.C. conductivity of ethylene propylene rubber
Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1983, 1983In recent years ethylene propylene rubber (EPR) has emerged as an important competitor of polyethylene as a high voltage cable insulator [1–6]. A survey of 120 utilities by R. L. Engsign [4] shows that 11% of them primarily use EPR for their insulation.

Peroxide Crosslinking of Ethylene-Propylene Rubber
Rubber Chemistry and Technology, 1964Abstract The crosslinking of ethylene-propylene rubber by means of cumyl peroxide has been followed in detail. The overall crosslinking efficiency has been found to be about 0.4 crosslinks per peroxide molecule, and this result has been shown by stress relaxation and permanent set experiments to result from a mixture of both scission and ...
