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?
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 is the glass transition temperature of silk?
The glass temperature transition is for glass, polymers, etc. (amorphous or semicrystalline materials), but not for leather.
