Advantages of Isotactic Polypropylene v/s Normal Grade PP

  1. Isotactic Polypropylene is a fractional MFI homopolymer therefore it has sufficiently better toughness than any other homopolymer.
  2. Due to the presence of atmospheric oxygen, Degradation and Oxidation of normal grade PP is inevitable, even when there is no direct sunlight, while ISOTACTIC POLYPROPYLENE is immune to such degradation & oxidation.
  3. Chemical resistance of ISOTACTIC PP is more than that of normal grade PP even at an elevated temperature.
  4. Isotactic polypropylene has excellent heat resistance upto 120°C as against 85-90°C of normal grade PP, w.r.t water.
  5. This grade is proven in pickling lines (CRM) as well as ARP in steel Industries for handling HCL containing ferrous & ferric chloride at an elevated temp, upto 110°C.
  6. This grade is also proven in Caustic Chloro Plant for application in brine for Anolyte and catholyte service upto 100°C temp.
  7. This grade is also proven in application of HCL with solvent traces such benzene, tolune etc. at an elevated temperature up to 110°C.
