YJ-35 XLPE cable insulation material is required to meet the strict standard in the cleaning aspect. In the overall production process, loading, processing and packaging are all strictly controlled; and the overall process is performed in a confined environment. The sample is tested by laboratory impurity detector in the production process periodically, and the impurity content of 1 kg-sampling complies with the following requirements:The impurity particles with 0.175~0.250mm diameter no more than 5; maximum  allowable  in  0.250mm.

Over a broad range of processing technique, YJ-35 can still provide excellent extrusion capacity and smooth surface. For optimum results, melt extrusion temperature in the range of 116 °Cto 132 °C are recommended. For further details, please contact our merchandiser.

 Keep away from sunshine and rain during the transport, and store in clean, dry and ventilated warehouse. The product may be stored for up to 6 months without opening at normal temperature.
