What else can I help you with?
Could you please let me know what the minus sign indicate in glass transition temperature of Polyethylene -125 degree?
The -125 degrees indicate the transition temperature of Polyethylene from glass.
Which is not a use for polyethylene?
Making jelly jars. Jelly is packaged at a temperature higher than polyethylene's glass transition temperature, so the jars would deform if you tried it.
What are the advantages of storing acid in polyethylene plastic bottle?
- the polyethylene plastic bottle is unbreakable- the glass has a solubility (low and dependent on the type of glass) in acids
Why polyethylene has two Tg?
this is a loaded question. Why do you think there are two Tg's? are you just doing something like DSC? if so do you see two 'bumps'? this does not mean two Tg's, it means there are two thermodynamic transitions taking place. Most likely for PE this is a crystalization and a glass transition.
What is the glass transition temperature of silk?
The glass temperature transition is for glass, polymers, etc. (amorphous or semicrystalline materials), but not for leather.

What is graduated cylinder made of?
Some materials are: glass, polyethylene, polypropylene.
What chemicals in budweiser boxes?
Packages for beer are glass, polyethylene or aluminium.
What is the difference between glass transition temp and melting point?
Glass transition point describes the temperature when material (crystalline or semi-crystalline) loses its crystallinity but not necessary melts. For instance, polyethylene's glass transition temperature is around -140-150C, while its melting temperature is around 105-130C (light and heavy species).
How is salt packaged?
In polyethylene bags or cardboard boxes. Rarely in glass bottles.
Is arsenic stored in glass?
Arsenic is not typically stored in glass due to its toxicity. Glass containers are not resistant to the corrosive nature of arsenic and can lead to contamination. Instead, arsenic is usually stored in specialized containers made of materials like polyethylene or HDPE (high-density polyethylene).
How chalcogens form glass and sHow is p-n transition?
how chalcogens form glass and show p-n transition
What is suitable material for a salt shaker?
Examples: glass, polyethylene, polypropylene, inox steel.
