Silcawool® | HT Soluble Cer. Fibre Textile Products

The base material of TESPE SILCAWOOL Textile Products consists of a new calcium/silicate Fiber (SILCAWOOL), with a small quantiy of organic fibers that decomposes from about 200 °C.
In order to ensure that the strenght is manteined at high temperature, the SILCAWOOL yarns are reinforced eithr with Steel wires ( for 1050 °C ) or glass filaments ( for 650 °C ).
Becouse of their technical peculiarities - high temperature resistence, low thermal conducivity, low density, high flexibility - TESPE SILCAWOOL Textile Products are the best substitute of the Ceramic Fiber Textile Products.
TESPE SILCAWOOL Textile Products do not contain any Ceramic Fiber nor Asbestos Fiber.
