These cords are made of coaxially twisted aluminosilicate yarns. Such a design provides high tensile strength and allows for simple, on-site adjustment of the diameter by untwisting. As with the previous cord, these two types fit exceptionally well over isolated surfaces that they are wound around.
Type 455 is made of aluminosilicate yarn on glass carrier.
Type 456 is made of aluminosilicate yarn reinforced with stainless steel wire.
These two types can be used as thermal insulation with all types of transfer ducts, heating installations, machinery and equipment. They are also used as static sealing in all types of chambers, driers and furnaces.
We generally recommend to use type 456, however, where the use of metal is not desirable, we recommend type 455.
