STUDY OF THE EFFECT OF DIOCTYL SEBACATE ON THE PROPERTIES OF EPICHLOROHYDRIN RUBBERS

The effect of different technologies for the introduction of a plasticizer - dioctyl sebacate on the properties of rubbers based on epichlorohydrin rubber of the Hydrin T-6000 brand was investigated. When using the technology of rubber swelling in a plasticizer, dioctyl sebacate exhibits a shielding effect, reducing the interaction of the filler-polymer, which leads to an improvement in low-temperature properties and a deterioration in the physical and mechanical properties of the material.

Investigation of the effect of plasticizer injection technology on the properties of epichlorohydrin rubbers

The influence of preliminary swelling of epichlorohydrin rubber of the brand is investigated Hydrin Т6000 in dioctyl adipate and dioctyl sebacate on the Physicomechanical characteristics and frost resistance of its vulcanizates. Revealed that pre-swelling of the rubber in the plasticizer, the plasticizer penetrates into the intermolecular space of the rubber and due to the shielding effect reduces the interaction of the filler with the elastomer matrix, which simultaneously leads to improved low-temperature properties and decrease of Physicomechanical properties of vulcanizates.
