EPDM/silicone blend was prepared with polyorganosiloxane compatibilizer for out-door polymer insulation used to shed. Each blend had various weight ratios, 100/0, 90/10, 70/30, 50/50, 30/70, 10/90, and 0/100 as EPDM to silicone, and electrical and tracking characteristics were studied with the method of IEC 60587. And also, tracking properties and contact angle related to UV-weathering period were studied to understand the degree of degradation of blend after 1000 h UV-weathering.

고분자의 블렌드는 새로운 성질을 가지는 재료의 제조를 위한 하나의 방법으로 제시되고 있다. 그러나 대부분의 재료는 재료사이의 점탄성, 표면에너지 그리고 상호결합력의 차이로 인하여 비상용성을 지니며, 이로 인하여 블렌드물은 예상되는 물성을 나타내지 못하는 경우가 있다. 실리콘 고무는 우수한 내열성과 전기적 성질을 가지며, ethylene propylene diene monomer (EPDM) 고무는 우수한 기계적 물성을 지니고 있다. 본 실험에서는 실리콘과 EPDM 고무의 블렌드를 통한 전기적 성질과 기계적 물성이 우수한 새로운 기능성 재료의 개발에 목적을 두었다.

Polymers are the most commonly used di-electrics because of their reliability, availability, ease of fabrication and cost. The commercial and industrial demand for advanced polymeric materials which are capable of being used in harsh environment is need of the hour. The study of the effect of electron beam irradiation on polymeric materials is an area of rapidly increasing interest. This paper discusses the resultant beneficial effects of electron beam irradiation on the SiR-EPDM blend having 50:50 composition. The changes in mechanical and electrical properties of SiR-EPDM blend which are exposed to three different doses of electron beam radiation namely 5 Mrad, 15 Mrad and 25 Mrad are presented. The irradiated blends are analyzed for their electro-mechanical and physico chemical properties. The electrical changes induced by irradiation are investigated by arc resistance, surface resistivity and volume resistivity measurements as per ASTM standards. The mechanical changes are observed by the measurement of tensile strength and elongation at break. Physico chemical investigation has been done using the FTIR, in order to investigate the irradiation induced chemical changes.
