Polyketone

• Excellent chemical resistance, to automotive fluids, hydrocarbon solvents, salts and weak acids and bases. PK exhibit higher resistance to hydrolysis in broad range of aqueous environment comparing to PA.
• 2-3 times higher impact strength compared to PA and PBT. And PK exhibit a high level of ductility over a broad temperature range.
• POKETONE™ are non-toxic, and used in the development of food contact and medical devices. PK are also safe with low volatile organic compounds emission. 
• Eco-friendly alternative to other engineering plastics, PK generate lower CO2 emission during the production process.
• Exeptional barrier properies, applicable for Reinforced Thermoplastic Pipe, food packaging and barrier film.
• Excellent wear resistance, even better that POM and reduces noise issues.
• Polyketone is strong, tough, and ductile. Tensile yield stress is 60MPa. Stiffness is moderate, with tensile and flexural modulus of 1.5~1.7 Gpa.
• Elongation at yield is very high(25%), and Polyketone polymers can subjected to much larger (repetive) deformation than any other engineering plastics before permanent deformation occurs.

Hyosung Chemical’s brand POKETONE™, is the world’s first commercialized polyketone. It is a non-toxic and biocompatible polymer that is FDA and NSF approved.

It exhibits excellent chemical resistance, excellent toughness, and abrasion resistance. With its balanced properties, POKETONE™ is widely used in markets such as automotive, water meter, water purifier, toys, medical devices, pipes and films.
