Unifrax Fiberfrax® Durapack™ Rope Packing

Durapack™ rope packing is a dense, resilient twisted cord style rope designed for packing applications that have irregular surfaces or openings. This product is pliable and exhibits exceptional sealing capabilities. An inorganic surface coating provides good resistance to mechanical abuse up to 538°C (1000°F), enabling Durapack rope to be effective in high-temperature seals, packings and gaskets. Durapack rope packing contains a small amount of organic carrier which will burn out at a low temperature with less than 3% shrinkage. It possesses the same thermal properties and chemical stability common to all Fiberfrax forms, resisting attack from most corrosive agents.Typical ApplicationsHigh temperature door sealsMold sealsGeneral maintenance in aluminum plants, foundries, refineries and power plantsExpansion joint packingInformation Provided by Unifrax I LLC
