Microwave Safe Functional PET THI-22 Waterproof Tear Resistant
THI-22
Main features
1,THI-22 is a toughened and enhanced injection grade fast crystallization functional PET prepared by adding high efficiency nucleator and other functional additives and granulation by double screw extruder.
2,Light yellow, opaque, easy to color, good fluidity; fast crystallization rate, Products with higher crystallinity can be obtained at lower mold temperatures (<100 ℃); The final product has excellent temperature resistance performance
Recyclable
Meet California Class 1 # recovery criteria; fully recyclable ( mechanical and chemical ) during PET recovery.
Safety and environmental protection
It can be used for food packaging and food contact substances to replace melamine; provide FDA, ROHS, PAHS (PAH) test reports, etc.
Application case:
PET tableware
