3M™ Dyneon™ Fluoroelastomer FC 2145 is a low-viscosity copolymer of vinylidene fluoride and hexafluoropropylene with a 65.9% fluorine content. This fluoroelastomer (FKM) does not include an incorporated curative, but is curable with amine or bisphenol-type curing agents.

A Versatile FKM
3M™ Dyneon™ Fluoroelastomer FC 2145 boasts numerous favorable attributes that make it suitable for use in transfer and injection molding, extrusion, calendering and coatings. It does not feature an incorporated curative, but is amine or bisphenol curable.

Dyneon fluoroelastomer FC 2145 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, FC 2145 should be banded on the mill prior to adding the blended dry ingredients. Once mixed, the compounded stocks have good scorch resistance and storage stability.

Offering Different Quantities to Meet the Needs of the Job
Dyneon fluoroelastomer FC 2145 is packaged in slab form 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 Ib (25.0 kg) boxes.
