Thermally Upgraded Papers

Cellulose based papers that are chemically modified to reduce the rate of decomposition. Ageing effects are reduced either by partial elimination of water forming agents (as in cyanoethylation) or by inhibiting the formation of water through the use of stabilizing agents (as in amine addition, dicyandiamide).  A paper is considered thermally upgraded if it meets the life criteria as defined ANSI/IEEE C57.100
