Role of phenol and phosphite antioxidant combinations in the thermal stabilisation of metallocene LLDPE (mLLDPE): Optimisation and performance and influence of metal stearates on multiple extrusions

166Concentration of I1010 after the first, third and fifth extrusion of mLLDPE stabilised with a phenolic AO I1010 (1000 ppm), a phosphite AO I168 (1000 ppm), and a metal stearate (1000 ppm) at 200 °C.
