        G60 Expansive Per Chloro Erhy Lene Fireproof Coating

        1、Product introduction
          Expansive Per Chloro Erhy Lene fireproof coating is a kind of special cable fireproof coating, made of Per Chloro Erhy Lene resin and chlorination rubber as basic material, with fireproof and blocking material, plasticizer and so on. The product has the characters of flame-resisting, oil-, water-, climate-proof, and strong adhesion. The fireproof coating becomes a coat after being dried. When the coat meets fire, it will expand to an even alveolate heat-insulation layer in order to prevent fire from burning the cables directly.
