Thin Film Material

At Precision Econowind LLC, we supply thin film material, for both coil forms and reinforcing collars, for customers who wish to manufacture voice coils or other electrical coils on-site at their facility. Thin film material is coated on one side with our proprietary high temperature adhesive capable of withstanding temperatures over 500°F. Many customers have found that in direct comparison with other electrical coils, this adhesive has been the difference in preventing coil failure especially in voice coil applications. The high temperature adhesive not only extends the life of the coil, it allows product designers more freedom in coil placement in space constrained situations.

Film materials include aluminum, nomex, stainless steel, polyimide, and fiberglass in widths up to 7 ½”. Polyimide is available in .002”, .003”, and .005” thicknesses. Aluminum is available in thickness between 0.002” and 0.010”. Fiberglass between 0.003” and 0.009” thick can also be coated. Stainless steel is available in .003” thickness. The most popular configurations are kept in stock for immediate availability. In addition to providing custom coil materials, we have extensive manufacturing capabilities for customers desiring turnkey custom coil winding services.
