For Finer and Smoother Surfaces

Ideal technology dedicated solely to grind up in pursuit of more beautiful and smoother surfaces: It was born of a combination of diversified needs for precision grinding and a special porous material with unparalleled possibilities.

 
PVA sponge, a material with sophisticated features, is used as grinding and polishing material. Taking full advantage of its continuous open pore, high porosity structure and flexibility, PVA sponge has established an advantage in the field of hyper-precision polishing materials as an elastic grindstone with very high quality finishing performance.

PVA sponge is a porous material with continuous open pores made from polyvinyl alcohol. Due to it's chemical properties the possibilities of agglutination and burr and thus scratched surfaces is prevented (self-cleaning). Also excellent abrasion resistance and chemical resistance allow PVA sponge to be widely used both in industrial and daily-use applications.

Difference is distinct in "soft-to-soft" hyper-precision finishing.

Grinding and polishing material, which use PVA sponge as a main or bonding material, have a good resilience, compatibility with workpieces and adequate grinding function that give them fitness for diversified materials or applications, and superb adaptability to any new technical requirements.

And it gives full play to its ability in works on materials with relatively soft physical properties. In delicate finishing of soft-to-soft, it clearly shows an unmistakable superiority in performance to other conventional grinding and polishing materials (ceramicalyor hard-ceramicaly bonded materials).
