At a time when technical support is becoming tough to find, it’s good to know that 3M maintains state-of-the-art testing and analytical labs, pilot manufacturing facilities, and most important, an experienced staff of application engineers.
This manual provides general guidelines that can be used as reference in compounding fluoroelastomers. In addition to data regarding the physical properties yielded by various compounds and processes, the effects of potential contamination and the general requirements of certain types of applications (such as O-rings, molded goods, and extruded compounds) are also discussed. For more specific guidelines for the materials used in specific applications, refer to the 3M™ Dyneon™ Fluoroelastomer Recipe Book.
3M™ Dyneon™ Fluoroelastomer LTFE 6320Z and LTFE 6350Z are terpolymers made from vinylidene fluoride, tetrafluoroethylene and perfluoromethylvinylether, and contain a cure site monomer.
The 3M™ Dyneon™ Fluoroelastomers Compound Recipes booklet is a guide for evaluating, processing, and troubleshooting FKM with certain 3M products.
The first step in developing an FKM part is determining a formulation to withstand the part’s future environment. The part’s environment will dictate the physical properties required for your rubber compound. This chart is an excellent starting point for developing that initial formulation.
