Having established a firm reputation in India's PVC & PE Cableindustry, it was only natural for Rallison to look at future value-addedproduct extensions. These cables consist of carbon and hydrogen compounds,which essentially contain low-density polyethylene molecules in the form oflong flexible chains.

On cross-linking, slippage between flexible chains can be prevented. Cross-linked polyethylene (XLPE) is a thermosetting compound. It softens at the crytahne melting point of polyethylene (85°C to 115°C) and assumes an elastic rubber like consistency, a property that it retains during further rise of temperature until it becomes carbonized without melting at 250°C to 300°C. All this strengthens LT-XLPE cables against stress cracking and gives them a greater resistance to fight ageing in hot air.
