Effects of titanate coupling agent on rheological behaviour, dispersion characteristics and mechanical properties of talc filled polypropylene

A commercially available titanate coupling agent, LICA 12 from Kenrich Petrochemicals was used to study its effect on talc filled polypropylene. It was found that the melt viscosity of the filled PP decreased and dispersion quality was improved in the presence of coupling agent. Further investigatio...
