PK has high toughness, sufficient tensile strength and flexural modulus, and balanced performance
Compared with Nylon, PBT has 230% higher impact strength. It also has excellent hydrolysis resistance. It maintains high tensile strength and impact strength under wet conditions, and has high elongation.
PK high heat deformation temperature: HDT is 200℃, can be used for a long time in high temperature environment
PK has excellent chemical resistance: chemical resistance is second only to PPS. Water and water vapor stability
PK has high barrier properties: hydrocarbons. Passed the permeability test of unleaded gasoline @93℃*15 days, better than Teflon, and the gas barrier is equivalent to EVOH
PK has good friction performance: its wear resistance is 14 times that of POM and it has excellent low noise
PK has high production efficiency, and high crystallinity polyketone helps to shorten the molding cycle
