PP sponge roller description: PP sponge roller anothe name is PP water roller,it is specially suitable for chemical etching of copper plating sponge roller, with polyethylene as a chemical bridge, improve the polymer structure of the micro-foam body, with good water retention, water absorption, wear resistance, drug resistance can prevent chemical etching of the substrate when the liquid spill, but also play an excellent oil treatment, dehydration and liquid cutting function Application PP roller usually used on Printed circuit board, inner board, gold plating process, stainless steel plate, liquid crystal display, semiconductor wafer, glass and other industries are the magic weapon of chemical etching process We can customized the tube into PVC or SUS or carbon fiber rob PP water roller is made by the technology of ultra-fine continuous foam pore size of 5-10 µ. It can instantly absorb water on the surface of objects. At the same time, the roller surface…
