Effect of chromium chloride on the mechanical and dielectric properties of EPDM rubber

Abstract

Measurements of Young's modulus, dielectric loss and a.c. conductivity have been carried out on EPDM rubber samples loaded with different concentrations of CrCl 3 (0,2,4 and 6 phr). The values of Young's modulus was found to be linearly dependent on the CrCl 3 content. Variation of the dielectric loss with temperature showed that CrCl 3 may act as plasticizer. However, at higher frequencies the dielectric loss was found to be independent of frequency and the rubber samples may behave as non-polar dielectric. Investigations of the a.c conductivity suggested that the conduction in these rubber samples can be described by small polaron tunneling. In addition, conductivity was found to increase with CrCl 3 content.

Study on the grafting of polystyrene onto ethylene-propylene-diene terpolymer through reversible addition and fragmentation chain transfer technique

“…[14][15][16][17][18][19][20] Recent developmental effort on controlled/"living" free radical polymerizations (CRP) have provided a revolutionary broadening of the spectrum of the materials capable of being prepared by radical processes. Through CRP, the control over the molecular weight (MW) and molecular weight distribution (M w /M n ) became possible to prepare polymers with well-defined architectures and compositions, such as block, graft, or star shaped copolymers.…”

Dielectric, Thermal and Water Absorption Properties of Some EPDM/Flax Fiber Composites

“…EPDM rubber has several uses in the automotive industry (profiles, hoses, seals), electrical and construction industries, aerospace or nuclear technology. EPDM is also utilized as a dielectric material for cable and wire insulation, especially cables in nuclear power plants which are subjected to thermal and radiation attacks during their utilization, and as an insulator matrix in rocket combustion chambers due to its excellent mechanical, chemical and electrical characteristics [ 7 , 8 , 9 , 10 ].…”

Enhanced interfacial interactions of isocyanate‐grafted graphene oxide/nitrile‐butadiene rubber nanocomposites: mechanical and thermo‐physical properties

“…It is well known that synthetic rubbers have no self‐reinforcing characters as they have no specific function of strain‐induced crystallization as natural rubber exhibits . Incorporating filler in polymer matrix is one of the most efficient ways to reinforce such synthetic elastomers . Normally, the reinforcing effect profoundly depends on three factors, the particle size of filler , the dispersion state of filler in rubber matrix as well as the interfacial interaction between the filler and matrix .…”
