Materials selection criteria

This is a good introduction to materials selection in plastics.  Another important factor to consider is chemical compatibility.

Most of the factors mentioned here apply in a general sense to materials selection for metals, as well as plastics.

Overall, a very nice article.

I agree.  This is a very nice article.  It's good to revisit.

Dave-that's a good point about chemical compatibility.

Agency Requirements

Good article.  In many electromechanical assemblies, Agency requirements can matter also.  A polymer may be the perfect match for the strength, finish, etc. needed for the product.  However, that particular grade of polymer may not have the flame retardant properties needed to pass 94V-0 at the specified thickness in order to achieve agency certification for the entire product.  It is important to also consider agency requirements up front during product development to make sure the entire product can be certified.
