Glass Transition Temperature-Hindi

This video will help to understand fundamental concepts of glass transition (Tg), experimental methods to determine it, factors affecting it and how to alter Tg of polymer depending on particular end-use.

Madam I had graduated last year from University of Calcutta from department of polymer science and technology. As a student I always felt void of channel like this for gate exam. I am very glad that you people took the initiative.

[@PolymerWorld]

Thank you for your comment. We are very happy that our channel is helping students like you. We hope that our channel reaches to as many students as possible. So please feel free to circulate our videos at different platforms.

Tomorrow is my polymer exam it's really helpful

[@PolymerWorld]

Thanks for your feedback. Good luck for exam.

[@BC-yr6eg]

Best explanation on youtube for me🙏🏼

[@BC-yr6eg]

Mam i am pursuing polymer engineering and there is only your channel which is providing videos based on gate XE papers......thanks mam

[@PolymerWorld]

Glad to know that you are pursuing polymer engineering... Let us know if you need any help.

[@samarthpawar1740]

Thank you 😊

[@ypsonar]

Knowledge lecture, Can you please suggest some good manufacturers of Epoxy Resin in India. . . Please

[@PolymerWorld]

We are not aware of too many epoxy resin manufacturers in India but Solvay, Aditya Birla Group (ABG), Hexion, Dow and Polynova resins are some of the many companies that we are aware of.

Nice teaching mam

[@PolymerWorld]

Thanks for your feedback!

[@mohitrajpootana8890]

Respected mam, can you please explain the question based on Tg in the gate 2010 polymer science question paper.
(Ques. no. 19 and 20)

[@PolymerWorld]

Please check community wall for solution.

[@preetirani193]

Mam more video explain in Hindi please

[@PolymerWorld]

More hindi videos are coming!

[@mamtanarwal5421]

Mam rheology and mechanical property pr bhi bna do😊

[@madhukiran5658]

For any polymer, between Tg and Tm which is higher and why?

[@PolymerWorld]

Tg is the temperature at which polymer shows segmental mobility (a part of the chain moves) where as Tm is the temperature at which polymer shows full chain mobility (whole chain moves), since mobility of whole chain requires more energy (heat or temperature) than mobility of small segment of the chain so Tm is always higher than Tg.

[@hetalpachchigar3950]

Can We calculate tg theoretically ?
In case we do not have any facilities

[@PolymerWorld]

Using WLF equation Tg can be calculate.

thx

[@PolymerWorld]

Thanks for watching!

[@ThilanNguyen-to6zf]

the sound is not good I am quite disappointed

[@PolymerWorld]

I am sorry to hear that. Please try this link to watch the video on glass transition temperature
