SELECTIVE BLEND OF EPDM-VMQ RUBBER FOR HIGH HEAT RESISTANT APPLICATION
Abstract
For some applications it is usually recommended to have high heat resistant elastomer materials. Compounds with blend of EPDM (Ethylene-Propylene Rubber) and VMQ (Dimethyl polysiloxane Rubber) or silicone rubber of medium and high VA (Vinyl Acetate is 45% and 70% in VMQ) along with ingredients are used in this paper to fulfill high heat resistant compound. Synthetic fabric was used as reinforcing agent with the rubber compounds. The physico-mechanical properties, rheometric characteristics, abrasion resistance and adhesion property with different textile members were studied for this selective blend. Ageing study was carried out on a vulcanized samples. Overall properties of EPDM/VMQ blends based on VMQ with high AV content are found to be better compared to blends based on VMQ with medium VA content.
