WebSIF® PVC coated foam resists chemical attack and has greater tear strength and compression deflection than uncoated urethane foam. SIF® Felt is a compressed, reticulated flexible foam made by permanentlycompressing a 90 pores-per-linear-inch (ppi) foam. Product Description Physical Properties The homogeneous structure of SIF® helps Web: The required SIF Response Time[1] (SRT). This is the interval between the SIF set-point being reached, and the hazardous event occurring. The SIF must detect and then operate its primary end elements, usually shutdown valves (SDVs) within this interval and do this quickly enough to keep the process variable below the design value.
