What else can I help you with?
Why is the glass transition temperature of polystyrene greater than of polypropylene?
Higher the glass transition temperature of the polystyrene can be attributed to the fact that sterically rigid bulky aromatic moieties like benzene in the styrene compared to that of aliphatic polypropylene
What is the meaning of polypropylene?
Polypropylene is a thermoplastic polymer used in many applications..
Polypropylene tensile modulus?
The polypropylene Young modulus is between 1,5 and 2,0 GPa.
Can Polypropylene be recycle?
yes
What type of plastic is a plastic disposable cup made of?
Polystyrene. the opaque white cups that you can make fingernails impressions in, are foamed polystyrene. Clear sups that you get on an airplane are general-purpose polystyrene.
Why is the glass transition temperature of polystyrene greater than of polypropylene?
Higher the glass transition temperature of the polystyrene can be attributed to the fact that sterically rigid bulky aromatic moieties like benzene in the styrene compared to that of aliphatic polypropylene
Are woofers made of polypropylene better than those made from aluminum and titanium?
Yes, woofers made of Polypropylene are better than those made from Aluminium and Titanium because they stand up to cold and heat better.
Can you use polypropylene plastic with gasoline?
No, it is not recommended to use polypropylene plastic with gasoline as it can degrade the plastic and potentially cause leaks or other hazards. It is better to use containers made from materials specifically designed to handle gasoline safely.
What is the most brutal plastic Polyvinyl-chloride polystyrene polythene polypropylene Teflon or PVA?
Clearly PVA m8
Are plastic cups better than polystyrene cups?
The majority of plastic cups can be reused or recycled. Polystyrene, or foam, cups are not widely recyclable. Cost wise, plastic cups tend to more inexpensive than polystyrene cups.
Is polystyrene a better insulator than metal?
Yes, polystyrene is a better insulator than metal. Polystyrene has a lower thermal conductivity, which means it is more effective at preventing the transfer of heat compared to metal. Metal is a good conductor of heat, so it allows heat to pass through easily.
Why is polystyrene a better insulator than wool?
Polystyrene has a lower thermal conductivity than wool, meaning it is a better insulator. Polystyrene is a synthetic material with a closed-cell structure, which reduces heat transfer through conduction. Wool, being a natural fiber, has a higher thermal conductivity and can absorb moisture, affecting its insulating properties.
Is rubber a best insulator or polystyrene?
Polystyrene is a better insulator than rubber. This is because polystyrene has a lower thermal conductivity, meaning it is better at reducing heat transfer compared to rubber. Additionally, polystyrene is often used in applications where higher levels of insulation are required.
Which is a better conductor wood or polystyrene?
Wood is a better conductor of heat than polystyrene. Polystyrene is a poor conductor of heat, making it a good insulator. Wood, on the other hand, conducts heat more efficiently due to its molecular structure.
Does a polystyrene cup hold more heat than a plastic cup?
Polystyrene cups tend to hold heat better than plastic cups due to their insulation properties. The material's structure helps to minimize heat transfer, keeping drinks hotter for longer periods.
What is the suitable organic solvent for polystyrene?
It depends on the molecular weight and 3-D structure of the polymer.
Is polystyrene ball heavier than iron ball?
No, iron is denser and heavier than polystyrene. An iron ball would weigh more than a polystyrene ball of the same size.
