ALWA POR MINERAL 4 (500 x 500 x 40 mm)

ALWA POR MINERAL

Here are all the advantages of ALWA POR MINERAL at a glance

  • is made of mineral particles and a resin binder.
  • is porous and produced as a block or slab in our factory in Gronau, Germany.
  • has a very smooth surface with good porosity.
  • is easily machinable.
  • is suitable for:
  • vacuum clamping technology,
  • filter applications,
  • aeration of aquaria, fish ponds and sewage treatment plants,
  • air film and sliding technology and many other applications.

Delivery forms: Blocks and slabs are available in different wall thicknesses

Please consider the different thermal coefficients of linear expansion if ALWA POR MINERAL is screwed on a slab or something is screwed on ALWA POR MINERAL (slab, block or mould). Drill larger holes for the screws into the material, so that the different expansion coefficients can level out. Screw connections which are used several times should be equipped with threaded sleeves.

On demand ALWA POR MINERAL can be produced with a smaller average por diameter (~ between 5 – 20 µ).
