This micro–finishing film product is designed for the surface finishing of industrial rollers and automotive parts (crankshafts and camshafts). Depending on the application, there are two thicknesses of anti-slip backing film material available, 3 MIL or 5 MIL. MI231A is manufactured to the highest standard using the most technically advanced materials and processes, capable of producing a consistently high quality film product. MI231A has a semi-open grain distribution that will resist surface loading and produce consistently fine surface scratch patterns during use. Application can be wet with lubricants or dry.
