The main disadvantages of GPPS are that they are brittle and fragile,have low impact strength,are poor in heat resistance,cannot withstand boiling water, and can only be used at lower temperatures and lower loads.Poor sunlight resistance and flammable. Black when burning,with a special odor.

  • Safe, environmentally friendly, free of PBA

How to distinguish a bottle made of GPPS or Tritan:

1. use finger nail to tap the bottle body,GPPS bottle are crispy,so the bottle sounds crisp.Tritan bottle are soft,so the bottle sounds dull.

2. Press the bottle body,GPPS bottle are hard to press,Tritan bottle are easy to press pit.

3. GPPS bottle are extremely transparent,very clear,Tritan bottle are little beige,not very clear like GPPS bottle.

4. GPPS bottle will be broken when drop on floor,Tritan bottle are breakage-proof.

5. Tritan bottle are heavier than GPPS,usually 8g per piece.
