Lexan 223R-701
(OP)
Currently using Lexan 223R-701 on a product with .080" wall. Looking for a material with similar mold parameters that would be stronger & not fail upon impact. Any suggestions or contact info of vendors that you can supply me.
Thanks
Thanks

223R is an easy flow mould release UV stabilised grade.
I would try a medium viscosity non mould release grade and I would not use UV stabilisers unless the environment of us required it.
From a wild guess based on your description of the part, it sounds like your problem is at a weld line. Weld line strength can often be improved by eliminating additives and improving the vents in the area of the weld line. Melt temperature and consistency, mould temperature, gate size, hold up time and pressure and injection speed can all have an influence on weld line strength.
You have not commented on my question about exposure to solvents. I cannot do your homework for you on that one.

I'll check into the med flow material too. Thanks

I'm not sure how much ribs will improve impact resistance. It may be more effective to design your whole round with no sharp edges to avoid stress concentrations.
