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.
Are you post-curing your silicone out of habit or necessity? Advances in silicone elastomer technology enable some manufacturers to eliminate this costly step for the first time. For example, a new liquid silicone rubber is the only one that exhibits the same physical profile before and after post-curing. This could potentially make post-curing unnecessary even in industries with strict regulatory requirements.
This comparative study between Millathane® XP-9075 and Millathane® 66 Premilled, along with a modified XP-9075 formulation for improved compression set show that Millathane® XP-9075 provides an excellent combination of oil and heat resistance, plus water and humidity resistance.
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.
