Two PET grades now dominate the global market, fiber grade PET and bottle grade PET. These standard grades differ mainly in molecular weight or intrinsic viscosity(IV). The average molecular weight ranges for bottle grade from 24000 to 36000 g/mol, which refer to an IV of between 0.75 and 1.00 dl/g. the standard bottle grade has an IV of 0.80 dl/g

Continuous Solid state polymerization (SSP) plants are characterized by longer residence times and larger product hold ups compared to the melt phase. this is due to the lower processing temperatures and lower bulk density of pellets compared to the melt.
Packaging industry is one of the fast growing divisions for PET usage. It can be water, soft drink, general foodstuff and even inedible liquids.
Excellent physical attributes like transparency, lightweight, strength and suitable price for this growth.
