what is the thermal conductivity for plastic? in J/s/m.C ? anyone know?.. i had it googled but cannot find the right one -_-...tq for answering

Question

anonymous · Answer

there's a typo ..its J/s.m.C...not J/s/m.C..sorry

mrnood · Answer

"Plastic" is not a material - it covers a very large range of different chemical compounds, with different values for conductivity. If you are concerned about units- look at you units - can you see another value for J/s ? Try this site for typical values http://www.engineeringtoolbox.com/thermal-conductivity-plastics-d_1786.html

Also re units:

C is not really used for temperature intervals - it is a value on the Celsius scale.

K is the correct unit to use BUT 1K = 1C so you can change C to K in your units

okay! i will try my best to fix the corrections! thank you! @MrNood

mrnood · Answer

can you see that

W/m.K

is the same as

J/s.m.C

anonymous · Answer

really!..after you said that.. now i just realised it ! haha @MrNood

anonymous · Answer

just now i did the experiment.. i think the plastic that i used , is the same material with the window plastic..maybe the fibre glass..

mrnood · Answer

a lot of 'windows' in plastic are polycarbonate (if very strong) or acrylic 

Fibreglass is not normally very clear transparent
