    PA46 is a high\u2011performance aliphatic high\u2011temperature\u2011resistant polyamide with a melting point of approximately 295\u00b0C. Featuring high crystallinity, outstanding high\u2011temperature rigidity, excellent fatigue and wear resistance, good flowability and short injection\u2011molding cycle, it is ideal for high\u2011temperature, repeatedly\u2011stressed and thin\u2011wall precision injection\u2011molded parts. It is widely applied in automotive electronics, connectors, new\u2011energy equipment and transmission\u2011wear\u2011resistant components.
