Filter Plates

This product takes advantage of anticorrosive characteristics and lightweight of PP, and we custom-manufacture large filter plates with maximum 2 by 2 meters squared.


  • Made from special grade PP plastic, excellent in fatigue characteristics.
  • Light-weighted and soft structured, as the product is made of PP. The specific gravity is 0.91, which is about 1/8 of a plate made of cast iron.
  • Provided with excellent corrosion resistance. Shows stable corrosion resistance against acid, alkaline and many other general chemicals.
  • In normal operations, the product can be used for a temperature up to 80°C.
  • For mass production, integral products can be enabled with a mold pressing. With mold pressing, circular projection shapes on filtration surface can be formed.

Compressed Plastic MembraneHISHI MEMBRANE

This is a plastic membrane that has both corrosion resistance and elasticity, developed by Mitsubishi Chemical as a first in the world. Compared with conventional rubber-based membranes, durability has been drastically extended. It is special mold pressing product and has standard and custom-formed products.


  • Compared with rubber-based membranes, the product has better thermal and chemical resistance in general, resulting in a longer life and improved advantages.
  • Product lineup responding to a wide range of applications and fields including general purpose, oil, food industry, and pharmaceuticals.
  • Wider applications in terms of temperature, acid, alkaline and oil compared with rubber squeezing membrane.
  • If using the existing filter press machines, HISHI MEMBRANE can replace existing rubber-based membrane, depending on manufacturers and models.

Corrosion-resistant Filter PlateHISHI MEMBRANE PLATE

PP-based anticorrosive filter-press-plate unit combined with HISHI MEMBRANE. Membrane can be easily replaced.


  • Equipped with plastic-based membrane.
  • Filter-press-plate unit integrated with PP-based filter plate.
  • Applicable for a wide range of fields.

Porous Plastic MaterialFILDUS™

FILDUS is a porous plastic material based on our excellent sintered plastic and proprietary manufacturing technologies.


  • Use of a single raw material of ultra high molecular weight polyethylene (UHMWPE) results in a clean material without any mixture with impurities.
  • With excellent chemical resistance and proper pressure drop, the product is suitable for various filters and powder fluidization bed.
  • When applied to filters, the product offers small pore sizes for excellent filtering performance.
  • As no toxic gas is generated when incinerated, disposal after use is simple and easy.


  • Various filter applications
    • Dust collector filters / powder collector filters / liquid-solid separation filters
    • Air track system
