Compounds based on fluoroelastomer polymers have high degrees of chemical and heat resistance, but can also experience problems in processing due to being chemically inert, which makes it difficult to add plasticizer and limits the filler loading of an inherently high hardness polymer. Current processing aid options can improve the processing characteristics of such compounds, but at some sacrifice to either curing or performance properties. 3M™ Dynamar™ RA 5300 is a new high performance rubber additive that can offer improved processing benefits to fluoroelastomer compounds with minimal changes to rheological and performance properties.
