Plastic Part Tensile Strength

Optimum safety factor is dependent on the application for any material...

Let's add another thought as well -

you might have a plastic selected with the properties you think are best, but this might only be likely in one type of environment -

Example - there are lots of various sanitizer systems to make "swimming pool water" - some plastics do very well during long time exposure to this long list of possibilities and some do not do well at all with some of the possibilities -

Question: if your product was going to be sold through distribution where you will never know who your customer's customer's customer is or what they use to produce "clean" pool water - don't you want to be sure to make your product(s) from materials that will live through the worst case scenerio?

Give some holistic thought as well to the DISTRIBUTION elements and the final ENVIRONMENT where your final product will have to live -

Just our two cents
