3M™ Dyneon™ Fluoroelastomer FE 5640Q is an intermediate viscosity copolymer of vinylidene fluoride and hexafluoropropylene with 66% fluorine. This fluoroelastomer (FKM) has excellent mold release and improved cure technology, resulting in more consistent part size from successive molding cycles.
Improved Cure Technology and Scorch Resistance
3M™ Dyneon™ Fluoroelastomer FE 5640Q 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 5640Q 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 clean running fluoroelastomer has a number of notable features beginning with the improved scorch resistance at high molding temperatures. In addition, the proprietary incorporated cure technology may help save time and improve throughput. The excellent mold release and improved cure technology will also help save time while maintaining 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 5640Q 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.
