4 PRODUCT SPECIFICATIONS
We are aware of only one source for the wide-format PTFE film rolls used at ASM: Plastomer Products Company. The film is marketed as Plasti-Thread PTFE Thread Sealant Tape. Widths of up to approximately 12 in. are available. For the widest possible dimension, request that the roll be “unslit.” The projects at ASM have all used .003 mm thickness film (0.7 gauge), the thinnest film made by Plastomer Products. A thicker film used for wire insulation is also available, but we found it less useful in our projects. The chemically inert, nontoxic, nonabsorbent, and nonflammable film is priced by the pound (1 lb. = approx. 150 ft.). Plastomer Products currently requires a 10 lb. minimum order. The cost per pound varies with the market price of the raw materials.
