Heat resistant material

dezignit · Oct 12, 2004

Hi, I am designing a device that is similar to an old fashioned kerosene lantern and requires a clear shroud that screens the flame from wind etc. The proximity of the shroud to the flame is approx 40mm. Needless to say, the shroud also has to be transparent. Any ideas on a heat resistant, transparent plastic that is injection mouldable?
Thanks and best regards,
Tappie

in order of increasing heat resistance (and cost), you can try: high-heat polycarbonate (PC), polysulfone (PSO), and polyethersulfone (PES).

For PC, try Dow and GE:

For PSO and PES, try BASF:

Bayer also had a high heat PC called Apec, but maybe even standard PC might do it, depending on the actual temperatures reached.

Is flammability an issue.

Is impact strength an issue.

dezignit,

I suggest that you take all situations into account.
For instance:

What if, the lantern tips over and spills the combustible fluid onto the clear lens?

What if, the combustible fluid flashes over?

These are simple reasons as to why companies like "Coleman" use glass.
