LyondellBasell has unveiled a new polypropylene resin -- Adflex 7492 XCP -- based on its proprietary Catalloy technology for a wide range of blown film applications. The new grade is said to provide outstanding combination of transparency and superior resistance to impact, puncture and tear propagation. With a film thickness of 30µm and 13 % haze value, the resin represents a new benchmark for highly-modified polypropylene grades. Produced using LyondellBasell's proprietary Catalloy process, Adflex 7492 XCP exhibits an exceptional balance of softness, film clarity and good processing performance sets a new performance standard for polypropylene used in transparent film applications.
Test results have demonstrated that the resin shows promise in co-extruded blown film applications, where the new Adflex grade was used in the core layer. The throughput that has been achieved is close to fractional MFR LDPE, and the finished product displayed excellent clarity when clarified PP skin layers were used. According to the company, using Adflex 7492 XCP in the core layer and mLLDPE skin layers for the final film delivers superior mechanical properties. As a result, the balance of stiffness, toughness and clarity of Adflex 7492 XCP has a potential to reduce raw materials costs.
