Polyphenylene sulfide is an engineering plastic, a high-performance thermoplastic.

Each engineering plastics usually has a unique combination of properties that may make it the material of choice for some application.

A lightweight, heat-resistant engineering plastic was used for the intake manifold.

"Demand has been exceptionally high," said Robert Wood, the vice president of engineering plastics at Dow.

Some polymers containing sulfone groups have gained prominence in the field of engineering plastics.

Over the years, the company diversified its product offerings into technical textiles, engineering plastics, chemicals and packaging films.

The engineering plastics typically used have high melting points and create little smoke when burned.

A hard, dense engineering plastic manufactured by applying heat and pressure to layers of resin-impregnated paper sheet or cotton fabric.

Bakelite is said to be easily laser-engraved; some hard engineering plastics work well.
