Sponge roller

Sponge Roller include PVA Sponge Roller, PP Sponge Roller, PU Sponge Roller and PVC Sponge Roller, normally these rollers are customized according to client requirement.PVA Sponge Roller: A porous elastomer obtained by cross-linking specific water-soluble resins, with a strong ability to absorb water due to the hydrophilic bonds in its molecular structure. Generally, the water absorption rate is 8-10 times its own weight, which is the best water absorption effect, the lowest price and the largest use of products.PU Sponge Roller: based on polyurethane resin through a special process to form a porous continuous foam with good resistance to chemical media good temperature stability and other characteristics widely used in OSP section cutting liquid and other processes, but the price is high and the water absorption rate is limited. PVC Sponge Roller: Based on polyvinyl chloride, the foam formed under specific process conditions has excellent chemical medium resistance. It is generally used for the cutting liquid of strong corrosion paragraphs, but the use is limited by high price. PP Sponge Roller: Based on polypropylene resin, the elastomer formed under specific process conditions has excellent temperature resistance and corrosion resistance, and is only used as cutting liquid and water blocking roller
