Does anyone know a good site or publication for general information and specs on various families of plastics? I am trying to find a good, easy to use, and comprehensive guide for asssiting in the design of products. Plastics are used to make extruded coatings or jackets, usually nylon or vinyl.
So far, I have only found tech sheets for manufacturers proprietary trade names. While these help, they are not general enough and do not always show the same properties or scales, such as in Rockwell hardness.
I need something more general for comparing, say, nylon 6 to nylon 11 to HDPE. I am mainly interested in mechanical and thermal properties, but would prefer a single comprehensive guide to include others such as electrical.
