  • How do you select the best process oil for your EPDM application? It is important to match the chemistry of the plasticizer with both the elastomer system and the end application performance requirements. EPDM is commonly used in applications like wire & cable, weather stripping, and roofing with all having different performance needs. This paper will review the key questions one should ask during the evaluation and selection process. Ergon has been placing high performance process oils in rubber applications for decades and would like to share an approach to the selection process, including a quick overview of the types of chemistries available in the market. Despite process oils being one of the cheaper components, careful consideration should be exercised when selecting the process oil chemistry to maximize performance. The process oil can affect the rubber’s processability, durability, ageing characteristics and more. In addition to the end application, it is vital to maintain or improve processability. The initial phase of this study screened 19 process oils to ensure that processability changes would not be a concern. Using both technical performance and commercial considerations five to six sample progressed to phase 2 testing focused on end application performance. In this phase the formulations, i.e., wire & cable, weather stripping, and roofing, and tests were tailored to the application highlighting the performance trend-offs as the process oil chemistry and viscosity changes
