Textiles

There is a bewildering array of textiles out there. Keramicalia has tested a vast range of them, and reduced the range to those that work really well in mouldings. We do not manufacture any of them, but stock all the best ones.

Fibreglass Scrim: Ours is alkali resistant, those which are not can yield terrible disasters with cementitious binders. Plain weaves unravel too easily, our twill is more stable. The hole size of 10mm is optimal for most ceramic and cementitious applications.

Fibreglass Mat: Normal mats have limited flexibility. Our stitched mat can do complex curves. (Curved along 2 axes).

Polypropylene scrim: for alkaline binders.

Alumina fibre: Amazing stuff, see Keraline


Woven Ceramic Fibre: keratex is a composite with stainless steel wire incorporated.

Aerogel fibre: Super insulation in flexible sheets.

Non-woven Text

Ceramic Fibre Blanket needs no introduction.

Skin Safe is an amazing new mineral wool, in blanket attached to diamond mesh, or boards.

IT DOES NOT ITCH!

Ceramic Fibre Paper: we stock 1mm and 3mm.

We also stock carriers for Keraforce, from 17g/m2 to 150g/m2

 

Miscellaneous:

SFK: “one side corrugated” cardboard used in pipe and cylindrical furnace manufacture.

Stiff plastic sheet: used over casting formers for very smooth surfaces.

Carbon fibre: sometimes in stock.

Carbon felt

Graphite paper

Expanded Metal: for anchoring abrasion resistant material to steel sheet.

Hexmetal: for anchoring abrasion resistant materials to steel sheet.

Skin Safe

We are now importing a French rockwool product that

DOES  NOT  ITCH!!

It is made by a new process in which no shot is produced.

You can rub it on your face!

We will be stocking soft boards  1,2m x 600mm x 25mm @ R273 + VAT each.

Wired mattress rolls  5m x 1, 2m x 50mm, ready to wrap around tanks etc. @ R2907/roll + VAT.

 

Keratex

Keratex is a woven aluminosilicate cloth, reinforced with fine nickel-chrome wires. Conventional refractory fibre blankets are either asbestos based or have organic material woven in. Keratex is completely asbestos free. Keratex contains less than 2% organic matter. It is very strong, flexible and light. Keratex can withstand 980°C. It is normally used as a screen for radiant heat from temperature sources much higher than 980°C, but the textile itself seldom reaches its temperature limit.

Keratex remains flexible at high temperature. It only breaks down slowly by abrasion. It does not shrink. It has very good chemical resistance. It is only attacked by hydrofluoric acid, phosphoric acid and strong alkalies. It is not affected by water and steam. Screens are not impervious, but stop most of the air flow through them.

Applications: Curtains to limit convection air flow at furnace doors. Curtains to separate different heat zones of furnaces or ovens. Screens to shield operators from radiant heat. Temporary screens for operators during gunning and hot repair. Protection of hot floors during gunning or other repair. Entrance and exit barriers in continuous heat treatment processes.

Width: 980mm.   Roll length: 42m.

Strips can be stitched with thin element wire.

 

Ceramic Fibre Blanket

Alumino Silicate Spun Fibre Needled Blanket 

Description and Application: 


Flexible needled ceramic fibre blanket made of long and large-diameter spun fibre. Good thermal stability and thermal shock resistance, good chemical stability and tensile strength, low heat storage and thermal conductivity.

Physical Properties:

 

Packaging : in cartons with plastic liner

Storage : in dry and weather proof stores

Health and Safety : refer to MSDS.

 

Keraline

A woven alumina fibre fabric which remains FLEXIBLE at and after high temperature FIRING!  We have no idea how this is possible, we import it and it works!


The main application is to cover ceramic fibre blanket and board to prevent CONTAMINATION of wares from loose fibre particles. It is widely tested and proven in the ceramic industry, mainly to protect glazes.

It requires specialized anchoring systems, which we also supply.

The material is pink when fresh and turns white after firing.

The pink is the sizing which allows the threads to be woven.


The price (2019) is in the region of R26 450.00/m2
