Fair




UV light resistance  



Poor




Max continuous Service temperature


80-1400 C




Min continuous Service temperature


-80-650 C  





Sterilization resistance (Repeated)

Conductivity)0.25 W/m.K





Drying before processing is highly recommended : moisture content should be a maximum of 0.2%.

The maximum permissible drying temperature lie in the range of about 80-1100  C

PA 6,6 is thermally
stable up to 3100  C, but above decomposition accelerates, the initial
products formed being mainly carbon monoxide and ammonia, and
caprolactam.






Strengths


Limitation




High strength and stiffness at high
temperature



High
water absorption and water equilibrium content




Good
impact strength, even at low temperature



Low
dimensional Stability




Very
good flow for easy processing


Attacked
by strong mineral acids and absorbs polar solvents




Good
abrasion and wear resistance


Proper
drying before processing is needed




Excellent
fuel and oil resistance


More
difficult to process than PA 6, due to its very low viscosity




Good
fatigue resistance






Good
electrical insulating properties
