Engineering Plastics

Engineering Plastics is a group of materials that have better mechanical and/or thermal properties than commodity plastics. 

In addition to the materials mentioned above, Seal Engineering AS can manufacture seals and other machined details in almost any other thermoplastic, each with unique properties to suit a given application. Most of these materials are also available with different fillers, widening the range of applications even more.
