Sponge & Stone

PVA Sponge & Stone

This PVA sponge roller, which has been used in a variety of industries for a long time, is highly valued for its excellent water absorption and cleaning performance.

Main Features

  • Roller-shaped PVA sponge
  • Can continuously absorb water by pressing against works and rotating.
  • This high toughness single-piece material is very flexible and elastic, therefore it does not fray like down or thread, and there is no reason to worry about damaging works.
  • Unlike ordinary brushes, the whole contact surface of the roller touches the item to be cleaned enabling thorough and consistent cleaning.
  • Options include a type consisting of only a sponge without a core and other types that are bonded to a PVC pipe or a customer-supplied metal core (mainly made of SS).

 

Application

Washing : Electronic components (Hard disks, silicon wafers, semiconductor devices, photomasks, glass panels for LCD, FPD, etc.)
Moisture absorption   : Glass (construction and automotive), electronic components (printed circuit boards and lead frames), vehicles (tires and floor mats), food products (packaged foods, glass bottles and laver), resin and film
Application : Resin, film (release agent and antistatic agent), paper (water-soluble adhesive)

 

pva sponge

This special urethane sponge has a continuous fine pore structure, high porosity and excellent water absorption, heat resistance, and chemical resistance allowing it to be used in a wide range of environments.

Features

  • Excellent water absorption / retention and wear resistance:
    Special urethane sponge of continuous pore structure that does not readily hydrolyze.
  • Flexible in shape and size:
    The sponges is applicable in all sorts of production machineries and devices in shape of roller, sheet and block form.
  • Rigidity that PVA sponges cannot match:
    It is capable of removing foreign materials that are almost fixed to the item to be cleaned.
  • Softness:
    Unlike PVA sponges, it remains soft when dried, sustaining water absorption and retention properties.
  • Heat resistance:
    Its heat resistance property allows the application at an ambient temperature of 100℃ or in hot water at 100℃.

 

Application

Washing : Electronic components (Hard disks, silicon wafers, semiconductor devices, photomasks, glass panels for LCD, FPD, etc.)
Moisture absorption : Glass (construction and automotive), electronic components (printed circuit boards and lead frames), vehicles (tires and floor mats), food products (packaged foods, glass bottles and laver), resin and film
Surface Coating : Resin, film (release agent and antistatic agent), paper (water-soluble adhesive)
Material protection : Optical Parts, Precision Parts

These polyolefinic sponge rollers, excelling in liquid-absorbing capacity, are employable even on strongly acidic and strongly basic solutions.

Material
Polyolefin-based sponge


Application

  • Liquid draining in plating and etching processes of printed-wiring boards, lead frames, etc.
  • Liquid draining, conveyance, and application in manufacturing process of various components.

These polyolefinic porous sheets of reticulated-foam structure may be employed in applications including liquid absorption, liquid retention, wipe-up, and filtration, under severe environments including strongly acidic and strongly basic solutions.

Application

  • Filtration & Absorption for gas and liquid
  • Liquid Transfer
  • Space for Electronic Parts
  • Humid Coordination(Sublimation
  • Ink Retainer & Supplier
  • Wiping Material

Possessing high-level porosity and a reticulated-foam structure, these elastic grindstones are capable of anchoring high-denier grit, making it possible to attain extremely uniform surfaces of high precision.

  • Due to the micro-elasticity of the bonding agent, scratches are not left on the work, allowing high-precision finished surfaces to be obtained.
  • Owing to the grindstones' high-porosity structural makeup, heat generation in polishing is slight, and clogging is unlikely to occur, sustaining stabilized grinding performance.
  • Varying the binding-agent properties and the grit, enables Crystal grindstones to be put to use in diverse applications, and to be employed broadly in precision finishing.
