Polyketone polymers can be characterized as strong, tough, and ductile. Tensile yield stress is 60MPa. Stiffness iss moderate, with tensile and flexural modulus of 1.5~1.7 Gpa. Polyketone polymers also exhibit good retention of stiffness.
Superior Resilience and Snapability
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. Polyketone polymers are also very resilient and well suited to snap-fir assemblies, allowing for relatively large design strain.
Very good Impact Performance
Polyketone polymers’ impact strength is unusually high and they exhibit a high level of ductility over a broad temperature range.
