biggamefish Posted April 20, 2015 Author Report Share Posted April 20, 2015 (edited) Im taking same thickness on both say like .093" Edited April 20, 2015 by biggamefish Quote Link to comment Share on other sites More sharing options...
Vodkaman Posted April 20, 2015 Report Share Posted April 20, 2015 For a realistic assessment of such a comparison, you really need to look at technical specifications. The technical units will be no more useful than opinions but comparing the numbers will give you a very good idea. This first link shows the numbers for PetG under the Izod impact test as 88 j/m. Compare with the numbers for polycarbonate Izod impact test as 600–850 J/m. A huge difference I would say. These materials are very different and designed for different purposes.

RayburnGuy Posted April 20, 2015 Report Share Posted April 20, 2015 It might help to know what your intended use for them is. Ben Quote Link to comment Share on other sites More sharing options...

Vodkaman Posted April 21, 2015 Report Share Posted April 21, 2015 Good decision, great for stencils and moldings, but no strength in PetG for lip abuse. Dave 2 Quote Link to comment Share on other sites More sharing options...
RayburnGuy Posted April 21, 2015 Report Share Posted April 21, 2015 I'd have to agree with Dave for using them on lips. To begin with PETG is not rigid enough for diving lips. Lexan is the time honored material for lips if you want a clear lip. Ben 1 Quote Link to comment Share on other sites More sharing options...
SlowFISH Posted April 21, 2015 Report Share Posted April 21, 2015 Seems like the question has been covered and you are smart for staying away. PETG is a "blended" PET.... PET is used in almost every beverage package out there and has good flexibility. durability all while being really clear. The difference in PETG is it's designed for a different application and the additives make it more brittle - while it has flex and usually acts just like PET - it has less impact resistance and will shatter. If you ever find a PETG beverage bottle (Look for clear with a thru handle) - don't drop it unless you have a mop and bucket handy. J.

Is that the stuff that the Glad brand of tupperware-type storage containers is made from? I know from personal experience it doesn't like to be dropped when it's full.

One fine example of it is the POM multiserve Juice bottle with the handle... and by fine I mean don't drop it!!! LOL!!! J. 1 Quote Link to comment Share on other sites More sharing options...
