Alkaline and oxidising chemicals, as well as concentrated acids, are used in the production of paper and pulp. As most processes run at raised temperatures, there is also increased corrosive action on steel and concrete. Rubber  lining systems are resistant to changing temperatures with simultaneous corrosive attack. Their application in couch pits, Hollanders, tubs, nutsch filters and bleaching towers can provide long-term protection of these plant components. Rubber  lining systems replace expensive alloys and contribute to cost-savings in the paper and pulp industries.
