PU Absorb Sponge Wheel for PCB Wet Machine

PU sponge roller description: PU sponge roller is made of Polyurethane sponge, which can instantly absorb water on the surface of the object, while the roller surface is kept dry and transported.  Water cut-off effect, superior water absorption, toughness, high friction resistance can be doubled to extend the service life of the roller, The roller does not need special water supply, and will not become dry and hard in a water-free state, and always maintains the roundness and elasticity of the roller appearance. PU sponge wheel Features: Always soft in both dry and wet condition, high temperature resistance 120 degrees, super absorbent, resistance toacid and alkali, without dust drop off. It's widely used on PCB, inner board, IC tripod, gold-plated process, non-embroidered steel plate, LCD display, semiconductor wafer, glass, etc...  PU roller using Purpose: Water absorption: small test, printed circuit board, frame, etc. Cleaning: computer hard disk, glass, me…
