Item No : Polyamide 9T PA9
Product Name : Polyamide 9T PA9T
PA9T is based on homo-polymer (melting point 306°C, glass transition temperature 125). When compared to other heat resistant polyamides, it has several superior features such as low moisture absorbency, high chemical resistance and superior dimensional stability.
PA9T is made from original monomer diamine (nonanediamine) in which the carbon number is 9. The chemical the constitution of PA9T is half aromatic polyamide from aromatic core and a long hydrocarbon as shown below.
Characteristics of PA9T
- The water absorbency of PA9T is the lowest among high heat resistant polyamides.
- PA9T has superior heat resistance (blister resistance) and corresponds well to lead-free solder.
- PA9T keeps its superior mechanical properties at higher temperatures.
- Due to its low water absorption, PA9T has a superior dimensional stability.
- Compared to other heat resistant polyamides, the electric properties of PA9T are stable for its low water absorbency.
- PA9T has superior chemical resistance in the class of heat resistant polyamides.
- PA9T also shows superior abrasion resistance, as do other polyamides as a typical property.
- The regrind of PA9T can be taken at 30-50% percentage with new virgin.
