Our selection of Taiwan imported equipment and raw materials of polyvinyl alcohol (PVA), water absorption capacity and service life is three times that of ordinary PVA sponge, high concentricity no eccentric phenomenon. Significant absorbency and water retention, mainly hydrophilic and continuous porous molecular structure of the material itself, the polyvinyl alcohol (PVA) materials for application in dehydration, absorbing and filtering and so on.
Scope of application: circuit board (PCB) inside and outside layer, BGA, IC tripod, liquid crystal display (LCD), dust-free wiping cloth, solar photovoltaic, semiconductor wafer cleaning
characteristic
1) hydrophilic absorbent, the temperature of 60 degrees, no crumbs, no degumming
2) before use, soak in water for 30 minutes, let the infiltration of liquid equilibrium roller (heating)
3) a wide range of uses, the price is low, PCB is commonly used in industry of sponge roller
A, technical index:
Smooth surface without pores, elastic strength
Water absorption capacity of up to 5-10 times its weight
The normal service life of 3 to 4 months
Two, technical parameters:
The use of temperature is not greater than 60 DEG C
Do not be water conservation
Don't avoid compression deformation
