We can tailor FKM products as per customer’s applications and requirements.Processing methods:Adopt typical FKM mixing formulations and conventional fillers and various additives to mix and process in cold enclosed mixing mill or open mixing mill. First, mix fillers and additives evenly, and then add FKM to mix and compound. Fluoroelastomer Pre-compounds FD2617 will have good storage stability and resistance to scorch after mixing evenly.Packaging : Carton Packing, 5Kg /bag, 20Kg /cartonQuality system : ISO9001 approvedTransportation: keep away from sunshine and rain during transportation, according to non-dangerous goods to transport
