The world of polyamides is gigantic and its variety enormous: PA6, PA66, PA46, and PA6T are just a few members of the large polyamide family. So why should a compounder like Bada, who already offers all these materials, still admit another new member to the family?
To answer this, one has to take a look at the property profile of this new star in the firmament: Badamid PA9T.
Hygroscopicity: Badamid PA9T with a water absorption of approx. 2% performs better than a polyamide 6 by a factor of four and approaches the value of the low-temperature polyamide PA12. In addition to its excellent dimensional accuracy, this value allows for excellent reflow soldering in the field of electrical engineering even after conditioning. Blistering during lead-free soldering is not an issue with Badamid PA9T components due to the low water content even after prolonged storage. In this context, it is important to emphasize its excellent dyeability and colour stability even after a reflow soldering process. This property makes this material the preferred match for coloured connectors.
Dimensional stability under heat: Near-engine applications are predestined for PA9T due to its high melting point and its glass transition temperature. Compared to PA46, both polyamides have melting points close to 300°C, whereas Badamid PA9T has a glass transition temperature of 125°C, which is more than twice as high. Thus, it shows very constant properties within a high temperature range.
Chemical resistance: Whether fuel, motor oil, liquid saline solutions or alcohols, you will always find our Badamid PA9T at the top of the resistance list compared to other competitive polyamides. Manufacturers of „quick connectors“ for fuel lines recognize the difference and often apply our material.
