Chevron Phillips Chemical: new metallocene-catalyzed HDPE film
A new metallocene-catalyzed HDPE (mHDPE) film resin shows an unprecedented mix of premium optics and stiffness. This is the latest addition and the first high-density grade in the mPact line of metallocene polyolefins made with a loop- slurry process by Chevron Phillips Chemical Co., USA. Earlier mPact grades for blown film have densities of 0,916, 0,918 and 0,933 g/cc. New Marlex D449 (0,942 g/cc, 0.8 MI) offers tensile modulus (1% secant) of 89,000 psi MD, 150,000 psi TD; 60d gloss of 127, and 7% haze. It also boasts good blocking resistance and it processes at LLDPE conditions, according to CPChem. The new resin is aimed at film overwrap for paper towels and tissues, food packaging and high-clarity/high-modulus converting film.
