PP Sponge Roller for Electroplating Process 

Feature of PP sponge roller PP sponge is specially suitable for chemical etching of copper plating sponge roller, using polyethylene as chemical bridge, improve the polymer structure of fine foam. It has good water retention, water absorption, wear resistance, drug resistance, can prevent the chemical etching of the base plate when the liquid spill, but also play an excellent oil treatment, dehydration and liquid cutting function. PP water roller application: Printed Circuit board, inner board, gold plating process, stainless steel plate, liquid crystal display, semiconductor wafer, glass, etc., the industry is the magic weapon of chemical etching process. Material application: chemical liquid cutting roller in etching tank Product features: chemical resistance, drug resistance, durability. (Sodium hydroxide, hydrochloric acid, 30% each, 20% nitric acid)
