For the production of hoses, various yarns are knitted or braided into a hollow sleeve. All variants (knitted or braided) can be impregnated with PTFE, graphite, or other special products.
Depending on the intended use and operating temperature, the following materials are available:
- Ceramic fiber (1260 °C): Ceramic fibers require reinforcement with glass fibers to be processed into yarns (this reduces the classification temperature of the textiles to 850 °C, since the glass reinforcement crystallizes at this temperature) or with metal fibers (classification temperature 1260 °C).
- Biosoluble fiber (1200 °C): Biosoluble fibers require reinforcement with glass fibers to be processed into yarns (this reduces the classification temperature of the textiles to 850 °C, since the glass reinforcement crystallizes at this temperature) or with metal fibers (classification temperature 1200 °C).
- Silicate fiber (1000 °C)
- HT glass fiber (750 °C)
- E-glass fiber (550 °C)
