Description / ApplicationRelease coating thickness is typically 0.0002 ±0.0001 in. (5.1 µm ±2.5 µm). For electrical insulation, coating thickness is typically 0.001 in. (25.4 µm). The manufacturer has coated silver-plated copper wire with diameters from 0.012 to 0.080 in. (0.3 to 2.0 mm) and on stainless steel wire from 0.001 to 0.040 in. (25 µm to 1 mm) in diameter.
Benefits Gained
Slip/release boosts output. Release-coated wire increases output rates of extruded small-diameter tubing and formed rubber bladders, and can provide similar benefits in other manufacturing processes, according to Applied Plastics
Fights contamination. The coated wire protects the purity of hot polymers or other materials that come in contact with it, thanks to the purity, chemical compatibility, heat resistance and strong adhesion to metal of Teflon®-PTFE finishes.
No flaking. Prior to coating, the wire is grit blasted providing an excellent surface for the coating to bond to.
Mandrels in stock. Applied Plastics stocks various small diameter mandrels.
Material Selected and Why
Teflon®-PTFE primer and finish provide a strong adhesion to metal, excellent release and insulation performance, heat resistance and uniform consistency for application as thin, smooth coatings.
