05-Oct-16 Availability of standard colors for aliphatic polyketone (PK) polymers has been announced by Clariant. The company supplies both finished compounds and concentrated color masterbatches using the resin and is believed to be the first supplier to offer these products in 12 standard colors. Additional standard colors are expected to be added over time and custom colors are available.
The polyketone colors, currently available only in North America, are part of a growing range of Clariant concentrates and compounds based on engineering resins and high-temperature plastics, which are used in automotive and other applications requiring a high melting point and impact, abrasion, chemical and fuel resistance. Fully compounded PK resin solutions have included glass-fiber reinforcement, conductive carbon black, PTFE, and other additives and fillers to meet new customer application requirements.
“Aliphatic polyketone was originally developed by Shell Chemical and sold under the Carilon® tradename,” explains Peter Prusak, Clariant Head of Marketing for North America, “but they withdrew it from the market in 2000. In 2014, however, the Korean company Hyosung Group reintroduced polyketone to the North American market through Polysource LLC, and that rekindled interest in the polymer.”
Polyketone has “the moisture resistance and frictional performance of polyacetal, the thermal resistance of polyamide [nylon] 6 and fuel permeability resistance that is nearly 10 times that of polyamide 12.” PK is reportedly ideal for applications in automotive, materials-handling, gearing and industrial applications replacing lubricated nylons and acetals.
