3M™ Dyneon™ Fluoroelastomer FE 5660Q

Incorporated Cure and Excellent Mold Release
3M™ Dyneon™ Fluoroelastomer FE 5660Q is a copolymer of vinylidene fluoride and hexafluoropropylene. It 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, Dyneon fluoroelastomer FE 5660Q 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.


Importantly, this product offers broad chemical and temperature resistance for durability and product longevity. In addition, FE 5660Q is a high viscosity version of 3M™ Dyneon™ Fluoroelastomer FE 5640Q that is clean running and has excellent mold release. The proprietary incorporated cure technology may help create more consistent part size from successive molding cycles.

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 FE 5660Q 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.
