Incorporated Cure Technology
3M™ Dyneon™ Fluoroelastomer FC 2120 has a number of favorable attributes that make it suitable for use in injection and transfer molding, extrusion and calendering. It offers broad temperature and chemical resistance for product durability and longevity. Additionally, the proprietary incorporated cure technology may help save time and increase throughput.

Dyneon fluoroelastomer FC 2120 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 2120 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
Different quantities are available to meet your needs. Dyneon fluoroelastomer FC 2120 is packaged in slab form and is available in a returnable bulk shipping container system for 1,320 Ibs (600 kg) of material.
