摘要

High temperature resistant stack support comprising a preferably dimensionally stable core which is surrounded at least in part by a high temperature resistant assembly of polyimide fibres of the general formula …… where n is an integer greater than 1 and A is a 4-valent aromatic group. …The stack support can be produced by shrinking a web of polyamide fibres of the general formula (1) onto the core by heating. …These stack supports are suitable in particular as supports for stacks of heated aluminium profiles, in particular during a heat treatment of the aluminium profiles. ……
