@Jim R. posted:Which is why you argue against metal castings anytime you can. You promote plastics with zeal. And ignore plastic failings without even vetting your obvious errors. Now you’re denying the plasticizer problem “indoors” ? My God, examples of toys that have melted onto other surfaces are renown, including on Lionel trains. I had one melt inside a furniture drawer at one time.
Try this thread for some samples and maybe follow my advice and do a Google search to learn more. And while you’re at it, try to gather some information on other plastics problems.
Jim, there are no obvious errors in my arguments. You present a lot of failure scenarios where an outside influcencer has caused a plastic failure, but none caused by inherent flaws in the material itself. Plastic doesn't just melt on it's own due to material defect. It doesn't just crack or break on it's own due to material defect. It doesn't just craze on it's own due to material defect. I have plastic items that are several decades old with no issues. No material is perfect. Not even plastics.
Your arguments against plastics reek of an infomercial for zinc products with catastrophe afflicting everything that contain plastic to make zinc look superior. Plastic is everywhere and serves reliably. Like anything, it won't last forever. It isnt isn't perfect for everything and it has it's limitations.
I have made my argument and you have made yours. We will never see eye to eye on this topic. I think it is time to let it rest.
