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.
Why polyethylene has two Tg?
Polyethylene has two glass transition temperatures (Tg) because it is a semi-crystalline polymer, meaning it contains both amorphous and crystalline regions. The amorphous regions have a lower Tg compared to the crystalline regions, resulting in two distinct Tg values for polyethylene.
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
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 chemicals in budweiser boxes?
Packages for beer are glass, polyethylene or aluminium.
What is graduated cylinder made of?
Some materials are: glass, polyethylene, polypropylene.
What is the difference between glass transition temp and melting point?
The glass transition temperature is the temperature at which an amorphous solid transitions from a rigid, glassy state to a rubbery state, without undergoing a distinct phase change. The melting point is the temperature at which a solid material transitions into a liquid state. The key difference is that the glass transition is a change in the physical properties of a material, while melting involves a change in its phase.
How is salt packaged?
In polyethylene bags or cardboard boxes. Rarely in glass bottles.
How chalcogens form glass and sHow is p-n transition?
how chalcogens form glass and show p-n transition
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).
What is suitable material for a salt shaker?
Examples: glass, polyethylene, polypropylene, inox steel.
