    Product Details

    Low shrinkage version of FE 5640

    Excellent Mold Release and Improved Cure Technology
    3M™ Dyneon™ Fluoroelastomer FE 5641Q 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 5641Q should be banded on the mill several minutes prior to adding the blended dry ingredients. Once mixed, the compounded stocks display excellent processing characteristics and storage stability.

    Dyneon fluoroelastomer FE 5641Q is a low shrinkage version of 3M™ Dyneon™ Fluoroelastomer FE 5640Q. This product offers a number of excellent features; it’s clean running, has low permeation and offers excellent mold release. The proprietary incorporated cure technology may help save time and increase throughput, enabling consistent part size from successive molding cycles. The benefits don’t end there; FE 5641Q offers broad chemical and temperature resistance.

    The Right Size to Meet the Needs of the Job
    This product is offered in different quantities so compounders and formulators can find the right size to meet the needs of the job. Dyneon fluoroelastomer FE 5641Q 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 lbs (600 kg) of material. The bulk container system is comprised of 48 individual polyethylene bags containing 27.5 lbs (12.5 kg) of product. Smaller quantities are available in 55.1 lbs (25.0 kg) boxes.
