GPPS is a colorless,odorless,glossy,transparent particle.Light weight,low cost,low water absorption, good colorability,dimensional stability, good electrical properties,transparent products,easy processing.
GPPS is soluble in aromatic hydrocarbons,chlorinated hydrocarbons,aliphatic ketones and esters but only swells in acetone.It is resistant to certain mineral oils,organic acids, bases, salts,lower alcohols and their aqueous solutions.Low water absorption, maintaining its mechanical properties and dimensional stability in a humid environment.Excellent electrical properties,high volume resistance and surface resistance,and not affected by changes in temperature,humidity,or corona discharge.Radiation resistance is also very good.
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.
Tritan sports bottle with infuser feature:
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.
There were many merchandiser import GPPS bottle and sell on Amazon,but the bottom engraved Tritan to cheat consumer.If you want a good plastic water bottle, you can contact us.
