LyondellBasell Petrothene® XL07425 Copolymer
Categories:	Polymer; Thermoplastic; Polyolefin
Material Notes:	Applications PETROTHENE XL07425 is especially formulated for use in flame retardant primary insulation for low voltage automotive wire and cable applications (SAE J1128). Non-discoloring antioxidant and special active peroxide have been added to ensure thermal stability during processing and optimum curing results. Processing Techniques XL07425, like other crosslinkable polyolefin compounds, can be extruded as wire and cable insulation by means of a conventional extruder with a continuous vulcanization tube. Below are suggested extrusion and curing conditions for XL07425. These conditions are intended as general guidelines only, and not optimum values, since manufacturing variables such as extruder type and size, continuous vulcanization tube design and cable construction all have an effect on processing crosslinkable compounds. Additional Suggestions Maximum screen pack of 40 mesh Little or no die land No predrying normally required Compression ratio of 2:1-3:1 "Mixing" screw can be used if properly designed to prevent excessive heat build-up Dies should be cleaned frequently to reduce compound build-up On-size dies are recommended Curing line steam temperature should be at least 400°F (205°C) Physical Properties All properties determined from compression molded, press cured plaques. The values listed for physical properties are nominal values only and are subject to normal variations consistent with the test methods and/or variations found acceptable to the industry. This product is from the former Equistar product line.
