The Resources of Raw Materials

Polyester wastes include:

 Waste polyester bottles

 Waste polyester pieces

 Waste polyester films

 Waste PETs

 Inviscid polyester

 Discharged raw materials

 Technical Roadmap

Process

Similar to PTA direct esterification reation:

semi continunous PET polymerization-waste ployester alcoholysis-polycondensation-filter-prill-melted material output.

Process

Waste ployester material melted by screw extruder to the horizontal polycondensation system (in the vaccum state, the material’s viscosity improved) - melted by Melt Polystyrene Pump-Filter-direct spinning.
