PEEK Polyether ether ketone, better known as PEEK, is a thermoplastic polymer that is resistant to chemical and steam. Mechanical Properties of Engineering Materials: These properties are concerned with the following properties: 1. This in addition to the plastic having good electrical and mechanical properties makes it an ideal material for fire helmets and face shields. Additionally, it would also eliminate use of larger “design safety factors” that result in “overengineering” or “overdesign.” Not only is such overdesign unwarranted, but it adds to the total part cost, resulting in a good example of ineffective design with plastics and a prime target for substitution by other materials.
