3M™ Dynamar™ Polymer Processing Additive FX 5920B is a free-flowing fluoroplymer based processing additive processing additive which contains 10% barium sulfate as a tracing additive.
FX 5920B utilizes our proven FX 5920A processing additive technology but contains 10% of a food grade Barium Sulfate as a tracing additive. It is a free-flowing fluoropolymer based processing aid that is designed for use at very low levels to improve processing of thermoplastics. At the very low use levels (typically 250-1500 ppm) necessary to improve processing, it does not alter or detract from the good physical properties associated with high strength plastics.
