PVA Sponge
Product Name
PVA Sponge
Belle-Eater A Series
Overview
Sheets and blocks of PVA sponge (porous body) with high porosity and fine continuous pore structure that can absorb and hold a large amount of liquid.
Characteristics
■It has a high affinity with various liquids such as ink and oil, and is a porous resin with a continuous pore structure with a high porosity. (It is not suitable for water absorption applications as it has almost no hydrophilicity.)
■As it is a porous resin with moderate hardness that is easy to process, it has excellent processability and can be applied to various shapes.
■As it is a resin of monolithic structure, there is no outbreak of fluff and fiber waste like fiber material.
Applications
Liquid absorption: | impregnation: printers, stationery, office supplies (ink), diagnostic agents (medicine), motors (oil) |

Cygnus Roller
Overview
A PVA sponge roller that has been used in various industries for many years and is highly rated for its outstanding water absorption and dehydration performance.
With a simple mechanism that presses against the workpiece and rotates, continuous water absorption is possible, and less water remains, and the amount of heat generated during drying can also be reduced.
In some cases, the drying process can be omitted.
Characteristics
■It is a roller-shaped (cylindrical) PVA sponge.
■Water can be absorbed continuously by crimping and rotating the workpiece.
■Since it is made of a material with a tough integrated structure, it is extremely flexible and has excellent elasticity, so there is no fluff or lint that falls off, and there is no need to worry about damaging the workpiece.
■There is a sponge-only type without a core, a PVC pipe, and a type glued to a supplied metal core (mainly stainless steel).
Applications
Water absorption (dehydration): | glass (building materials, cars, FPD), printed circuit boards, lead frames, tires, car mats, packaged food, glass bottles, resins/films |
Coating: | resin, film, paper (water, water-soluble glue) |

Belle-Clean
Overview
Extremely soft wet wiper that can be used with water.
Fine pores reliably catch particles and moisture, and unlike paper and fiber materials, it does not fluff or fall off, and can be recycled.
Characteristics
■The soft texture when wet allows it to fit any object, and its fine pores reliably catch particles.
It has excellent water absorption and water retention, and quickly absorbs and retains moisture.
■As it is made of PVFM (polyvinyl formal) resin, it does not fluff or come off like paper or fiber materials, and has excellent abrasion resistance. For these reasons, it can be reused.
■There is a type that wipes off by hand and a mop type that is ideal for cleaning floors and walls.
It can be widely used not only in clean rooms but also in places where clean environmental protection is required.
Applications
Liquid absorption (wiping off): |
For wiping electronic equipment, optical equipment, pharmaceutical manufacturing equipment, and workbenches. Cleaning in clean rooms. |

Micro Breath
Overview
Microorganism immobilization carrier for wastewater treatment and deodorization treatment using PVA sponge, which has many features such as high porosity, fine continuous pore structure, excellent abrasion resistance, and affinity with microorganisms.
Characteristics
■The PVA sponge has a high affinity with microorganisms, and has a continuous pore structure and a high porosity (approximately 90%), enabling high processing efficiency as a microorganism immobilization carrier.
■As it has excellent abrasion resistance and is not decomposed by microorganisms, it can be used for a long time. This saves time and money for replacement and replenishment, making it very economical.
■There is a soft type that absorbs water and becomes flexible, and a hard type that does not soften even in water and retains its shape while maintaining its shape.
