Tairilin 7730 is a homo type polyethylene terephthalate resin with intrinsic viscosity of 0.730dl/g. This resin is produced from the use of a special catalyst, which is free of conventional antimony and cobalt heavy metals.
The optimized recipe makes 7730 resin to have very low carboxyl end group, this is very advantageous for better thermo-stability and better hydrolysis-stability, which are very important requirements for engineering plastics applications.

Tairilin 7730 resin possess faster crystallization speed which is advantageous to many industrial applications.
Tairilin 7730 resin is produced in a state of the art continuous polymerization technology and is combined with a strict quality monitoring system.  The production facilities producing 7730 resin
are approved by ISO9001, ISO14001 and OHSAS18001 systems to confirm its outstanding quality of the product. 
7730 resin is an environmental friendly product with the important advantage of being totally recyclable.
