Commentary

UnlikePA6 and PA66, PA6T incorporates an aromatic ring in its molecular chain, resulting in a high melting point and high strength.
PA6T: polycondensation of hexamethylenediamine with terephthalic acid
・PA9T:polycondensation ofC9diamine with terephthalic acid
・PA MXD6: polycondensation of meta-xylenediamine with adipic acid

Key points

Semi-aromatic PA reinforced with glass fiber, etc.has high stiffness, low coefficient of linear expansion and water absorption, low dimensional/strength change and good for with metal insert process.

High heat resistance, used for electrical and electronic parts compatible with lead-free solder.

Aramid, a fully aromatic structure, is even High strength and difficult to mold (Kevlar fibers are generally well-known)

Medical Electrocautery

Reason for adoption

Its can be molded that long, thin forceps-like arms comparable to those of metal instruments (excellent rigidity, strength and fluidity), gamma ray resistant sterilization

Surface Mount LED Reflector

Reason for adoption

Heat resistance to withstand surface mount technology (high heat resistance)

Automotive crashworthy armor module

Reason for adoption

Excellent specific strength and impact resistance of polymers, reduced number of parts and weight by injection molding
