We are offering the following materials:
ALF textiles, max. use temperature up to 1400°C
Silica textiles, resistant up to 1000°C long term
HT-Gass textiles, resistant up to 750°C
E-Glass textiles, with and without coating, resistant up to 550°C
ALF Textiles are made of aluminumoxide and siliciumdioxide. The special production process and the high quality materials, guarantee application temperatures up to 1400°C.
They are available as plied yarn, braided hoses and woven textiles. Certainly you can have any insulation pillow, made of these materials.
Regarding “shrinkage”, ALF shrinks approximately 2% after being exposed at 1300°C for 24hrs as a result of transition of crystal type or phase from γ-Alumina and amorphous SiO2 to Mullite.
There is no weight loss, except binder that vaporizes due to exposure to high temperature. This is different from products that contain boron.
Additionally, HILTEX ALF is not affected in the atmosphere of extreme low temperatures like liquid nitrogen (-196°C).
Usually, HILTEX ALF has a good resistance against Strong Acid even in at high temperature atmospheres, except phosphoric acid. HILTEX ALF can be used in conditions including acid gas such as Hydrochloric acid, Sulfuric acid and Nitric acid without any problems.
Commonly known strong alkali like Sodium hydroxide and Potassium hydroxide, which have a corrosive effect on HILTEX ALF. Ammonia is an exception as there is no reaction.
Silicate textiles are very resistant against corrosion and chemicals. They are insulating excellent electrically and remain flexible and soft to touch even after use in high temperature, up to 1000°C long term.
Except these excellent characteristics, silicate textiles have a perfect resistance to thermal shock. They resist to fluid Aluminium and to molten metal (steel) splashing, as well as to the direct flame impact.
Silicate textiles are often used for filtration of fluid iron.
They are as well used:
HT Glass textiles
Our textiles are available as
Woven cloth, with coating, laminations, stainless steel reinforcement
Woven tape, 0,2mm – 5mm thickness, 10mm – 450mm width
Insulating sleeving from 0,3mm – 100mm diameter with different wall thicknesses
Needled blanket with densities of 180g/m² - 1440g/m² and thicknesses of 4mm – 25mm
The following product variants / coatings are available.
All silicate textiles are available in loom state. The 600g/m² cloth and the 1220g/m² cloth are as well in preshrunk version available. All other styles on request
For some fabrics, a weave lock coating is available. This coating allows a easy processing, cutting of the textile, without fraying fibres
HT Finish up to 1100°C for Silicate cloth
This Coating protects the fiber up to 1100°C of mechanical influences.
Metal wire reinforced silica textiles S2026
These textiles have been reinforces with V4A wires whereby it is strongly mechanically resistant
For the 600g/m² and the 1220g/m² silicate textiles, a one or two side PU-Coating is available as standard. For all other types on request.
For the 600g/m², and the 1220g/m² silicate textiles, a one or two side Silicone-Coating is available as standard. For all other types on request.
For the 400g/m², the 600g/m², and the 1220g/m² silicate textiles, a Vermiculite coating on one or two sides is available as standard. For all other types on request.
