PU sponge is very different from PVA sponge because it is soft when it is dry. It also has amazing abrasive resistance and chemical stability. It is an excellent media for brushing, liquid absorption and injection. It has roller type and plate type.

◆ Continuous foam with ultrafine pore size of 5 ~ 10um which can instantly absorb liquids while keeping the surface moist. It has liquid supplying, dehydrating, and isolating properties.

isolation, reduces production drying temperature, and increase production performance of 6 ~ 8M/min. The product does not chip, and is lint free. It can endure temperature up to 120C. Excellent resistance to abrasion allows the roller to have long product life.  

◆ Does not need moisture to make it soft. The roller will not turn hard when it is dry. It can also maintain its shape, flexibility and liquid absorbency.

[The main purpose]:

◆ Prevent discoloration, dust and water waste in coating process
◆ The removal of dust and waste before and after hot-pressing process

◆ Water treatment before and after washing circuit board, drying machine press and delivers roller.
◆ all kinds of water isolation and treatment works.
◆ Fluids absorption: circuit boards, lead framework.

◆ scrubbing: hard drive, LCD glass.
