Tarnamid A (PA66) – polyamide 66

Polyamide 66 is a product of the polycondensation of adipic acid and hexamethylenediamine. A crystalline material. Density: 1.14 gcm3. Melting point: about 255°C. In comparison to PA6, lower moisture absorption (2.2-2.5%) as well as better mechanical and sliding properties. The highest thermal resistance among polyamides. Glass fibre reinforced grades: increased specific gravity (1.60 g/cm3), very high stiffness, higher creep resistance, and high dimensional stability. Temperature range for continuous operation: from -30oC to +120oC.
