I am look for suppliers to make Micro-Perforated Panel. Any recommendations? What are manufacturing methods to produce MPP? Can MPP be made out of plastic plate?
More specificly, the MPP that I am interested in is made pf plastic material with 0.5 - 2mm thicness. The hole diameter is around 0.5-1 mm. I would like to use it for engine air intake noise control. Wondering if I can get some samples for testing porpose.
