Materials used

GLASS 550°C

The raw material used for this range of product is glass fi bre 550°C E type, inorganic, sterile and incombustible which is texturised or voluminized and then twisted. The fi bre diameter is 9 µ, in order to avoid any problem of irritation. Glass fi bre products are used for applications with temperatures up to 550°C, oils, chemical agents (except sodium silicate) thanks to their good thermal and mechanical resistance. Good elasticity, high pliability, low thermal loss.

HT GLASS 750°C

HT Glass fi bre is subjected to a special chemical treatment which increases the yarns’ thermal resistance. The diameter of this fi bre, 9 µ, makes HT glass fi bre products safe (they conform to European norms). They are used for applications with temperatures up to 750°C, oils, chemical agents (except sodium silicate) thanks to their high thermal and mechanical resistance. No thermal loss. The basic yarns can be of different colours (light blue, blue, brown, grey) according to the customers’ needs.

CERAMIC

Ceramic fi bre textiles are made of aluminium silicate yarns. Standard types contain 15-20% of organic fi bers which are added during the carding process. The organic fi bers burn at mediumhigh temperatures, but the thermal and physical characteristics of the product remain unaffected. The basic yarns can be reinforced with glass fi bre yarns to stand to temperatures up to 650°C or with inconel wires for temperatures up to 900°C. Ceramic fi bre items are ductile thanks to the low density of the raw material and they guarantee an outstanding resistance to high temperatures and chemical agents (except strong bases, phosphoric and hydrofl uoric acids).

CARDED HT GLASS EVOLSOLUBLE 1260

Carded HT glass fi bre (SiO2) yarns are produced thanks to a centrifugation process of glass that permits to have a SOLUBLE material and a safe product, both from the sanitary and ecological point of view (dissolution rate 294 ng/cm2 hr). The standard products contain about 20% of organic fi bers which are added during the carding process and 80% HT glass. The organic fi bers burn at medium-high temperatures, but the thermal and physical characteristics of the product remain unaffected the fi re loss is low (2%). The basic yarns can be reinforced either with fi berglass yarns, to resist to temperatures of 650°C or with metal wire, to resist to temperatures of 1050°C. Carded HT glass fi ber products have a green shade in order to make them identifi able at once and to distinguish them from similar materials, such as ceramic.

PAN (POLIACRILONITRILE)

PANXIDE fi bre, exclusive production Evoltex, is made of carbon fi bre blended with kevlar fi bre. This special mixture, which is studied to meet the most stringent requirements, gives PAN (polyacrylonitrile) fi bre an outstanding tensile strength and a good resistance to temperatures (up to 300°C), organic solvents, acids, alkalis, oils and fuels. The large diameter of the fi ber (15 µ) makes PANXIDE the safest alternative to asbestos and offers greater hygienic safety.
