Different Types of Sponge Roller

Sponge roller can instantly absorb the water on the surface of the object, while the surface of the roller remains dry, and has the effect of transport, extrusion, water removal and water cut off, with strong water absorption and water cut off, reducing the production drying temperature and greatly improving the production speed.

1. PVA Spong Roller

Material characteristics:
PVA Sponge Roller has excellent acid and alkali resistance and durability
Application:
Suitable for PCB inner and outer layer, BGA, IC tripod, LCD display, clean room wiping cloth, semiconductor wafer cleaning brush roller, glass industry, food industry, steel plate industry, etc

2. PU sponge roller

PU Sponge Roller adopts Japan's advanced ultra-fine continuous foaming technology, superior water absorption, toughness, friction resistance, longer service life. It does not change after absorbing water.
Dry hard, high temperature resistance 110 degrees, super absorbent, toughness, resistance to friction, no chips

3. PP sponge roller

Introduction
A new product specially developed for the chemical extrusion fluid of base plate. Using polyethylene as a chemical bridge, improved polymer structure of the micro foam.
Characteristics
Heat resistance, alkali resistance, wear resistance, acid resistance, liquid cutting
Matters needing attention
① When not in use, it should be often maintained in clean water to avoid deformation
② The use environment should not exceed 80℃, which will shorten the use period of aging
③ Every day with water extrusion cleaning can increase the service life of the sponge roller, can maintain the roundness and elasticity of the roller shape

4.PVC sponge roller

PVC Sponge Roller density is high and adopts continuous foam foam, strong water absorption, easy to clean and not easy to residual chemical agents
In the dry state can maintain elasticity and softness, and not dry hard, no need to add water moisturizing
Strong friction resistance, not easy to drop chips, tensile strength, not easy to deformation
Good drug resistance, for general organic solvents have chemical resistance, long-term placed in acid, alkali solution, it is not easy to change
