PU/ PVC/ PP/ PVA Sponge Roller

Sponge Roller

PU Sponge Roller

PU sponge roller Usage: Absorbing water at for part of drying section after rinsing and washing. Characteristic: Perfect hydrophobic capacity, 120℃temperature resistance, good tenacity, high wear resistance, chemical resistance (CuCl2, HNO3, HCl each 10%). It can keep wateriness without feeding water and keep soft and in round shape. 5 times as PVA SPONGE service life.

PVC Sponge Roller

PVC sponge roller Usage: Absorbing water in etching processing or after rinsing and washing. Characteristic：Perfect hydrophobic capacity, 60℃temperature resistance, good tenacity, high wear resistance, chemical resistance （HCl, H2SO4 each30%, H3PO4, NaOH, NH3H2O each 10%) It can keep wateriness without feeding water and keep soft and in round shape.

PP Sponge Roller

PP sponge roller Usage: Absorbing water in etching processing\ Characteristic: Perfect chemical resistance（NaOH, HCl, H2SO4 each 30%, HNO3) Thanks to its high chemical resistance and absorption, it can prevent the chemical from going bad and flooding out.

PVA Sponge Roller

PVA sponge roller Usage: Absorbing water after rinsing and washing Characteristic: Hydrophobic, 60℃ temperature resistance In order to make the water infiltrated evenly into the sponge, PVA sponge roller should soak for 30minutes before using. PVA sponge widely used in PCB industry, lowest cost.
