Need extremly durable, light weight plastic material.

Need extremly durable, light weight plastic material.

Need extremly durable, light weight plastic material.

I posted this question in the materials section and then decided to post it here also. I am designing a plastic part that is 4ftx3.5ftx1in. I can design in a majority of the lightness, but need to know several materials to begin looking at. Part will see some major abuse. Any suggestions on a material to try?

RE: Need extremly durable, light weight plastic material.

You might consider PFA (PerFluoroalcoxy Resin), it's expensive but has a very nice balance of engineering properties such as rigidity and abrasion resistance, and is well suited to abusive situations - (that sounds kinda funny), but true.

Some other materials that come to mind include Phenolic, UHMWPE, HDPE, etc.

Hope that is helpful

RE: Need extremly durable, light weight plastic material.

I almost forgot, you can also probably do a search of various materials on www.globalspec.com - and on GE Plastics web site (I believe it's www.geplastics.com but not certain)

best of luck!

RE: Need extremly durable, light weight plastic material.

As per RIVetron above UHMWPE is excellent for both mechanical and chemical abrasiveness. UHMW might be a better alternative to PTFE (teflon) in terms of cost but I believe it has a higher density.
