3M™ Dyneon™ Fluoroelastomer FX 3729 is a copolymer of vinylidene fluoride and hexafluoropropylene. This FKM has a fluorine content of 65.9% and a low Mooney viscosity for hose, tubing, and extrusion applications.
Chemical and Temperature Resistance 3M™ Dyneon™ Fluoroelastomer FX 3729 is a copolymer of vinylidene fluoride and hexafluoropropylene. Dyneon fluoroelastomer FX 3729 can be compounded using standard water cooled internal mixers or two-roll mills with standard fillers and ingredients utilized in typical fluoroelastomer formulations. The dry ingredients should be blended before adding to the masticated gum. For best results, FX 3729 should be banded on the mill several minutes prior to adding the blended dry ingredients. Once mixed, the compounded stocks have good scorch resistance and storage stability. This product has an incorporated cure technology that may help save time and increase throughput. In addition, this product produces smooth extrudates without the use of processing aids, and can be formulated to yield good permeation resistance to automotive fuels. The benefits don’t end there; Dyneon fluoroelastomer FX 3729 has low permeation and offers very good chemical and temperature resistance to create durable and long-lasting finished products. The Right Size to Fit the Job This product is sold in different sizes, so compounders and formulators can pick the right size for the job. Dyneon fluoroelastomer FX 3729 is packaged in milled slab form (as opposed to unmilled forms like crumb) and is available in a returnable bulk shipping container system for 1,320 Ibs (600 kg) of material. The bulk container system is comprised of 48 individual polyethylene bags containing 27.5 Ibs (12.5 kg) of product. Smaller quantities are available in 55.1 Ibs (25.0 kg) boxes.
