Engineering Polymers

KeyPlast®: A spectrum of bright, high performance colorants for plastics

High heat engineering polymers are used for their ability to withstand elevated or extremely low service temperatures without the loss of physical properties. They are used in demanding applications like power tools, automotive parts, gears and appliances. The combination of high processing temperatures and amines present in engineering polymers make most traditional dyes unsuitable for use.

Milliken’s range of high heat stable colorants perform brilliantly in extreme temperatures in various engineering polymers, including Polyamide, PolySulfone, PEEK, PPO (Polyphenylene oxide) and other high heat polymers and alloys.
