These types are produced by over-braiding a core with aluminosilicate yarn. The core consists of either a bunch of aluminosilicate yarns, or soft aluminosilicate fibres. In result, these cords are both soft and mechanically durable.
Type 475 is made of aluminosilicate yarn on glass carrier.
Type 476 is made of aluminosilicate yarn reinforced with stainless steel wire.
These cords can be used as thermal insulation with all types of transfer ducts, heating installations, machinery and equipment. Thanks to their softness and elasticity they are also used as static sealing in all types of chambers, driers and furnaces.
We generally recommend to use type 476, however, where the use of metal is not desirable, we recommend type 475.
