Pre-vulcanized Butyl Rubber

Butyl Rubber has very good resilience and elongation. Good resistance to aging, ozone, low and high temperature, especially to a big range of medium, such as any concentration of hydrochloric acid HCl, phosphoric acid H3PO4,40% sulfuric acid H2HO4, alkali( 40% sodium hydroxide NaOH, potassium hydroxide KOH), seawater, saturated saltwater. It is used for cutting gaskets and other general industrial purpose applications which will contact with above-referred mediums. Butyl rubber sheet also works on the lining field, for instance, Acid and alkali storage tank in chemical, chemical fertilizer, metallurgy, electricity factories, equipment contact with acid-base, isolated layer underfloor to prevent acid-base leak into underground water.
