The so-called Arlen, by introducing an aromatic ring into its basic molecular chain, achieves high heat resistance with a melting point of 320°C, and also solves the problem of weak water absorption of conventional polyamide resins.
By adding a third component to modify it, it maintains good molding properties while maintaining a polymer structure with a balance of heat resistance and low water absorption. It is very suitable for the polyamide of the SMT lead-free soldering process supported by IT technology in recent years. resin.
Arlen is Mitsui Chemicals' first self-confident work in the field of modified polyamide 6T to be mass-produced.
● High heat resistance: Arlen E series not only has a high melting point of 320℃, but also has very good fluidity during molding.
● Low water absorption: The reason for the high water absorption of polyamide is that the amide groups in the molecular structure form hydrogen bonds with water molecules. Arlen achieved the low water absorption of PA46 1/3 by reducing the concentration of amide group which is the cause of water absorption.
● High mechanical strength: The rigid aromatic ring and low water absorption in the Arlen molecular chain achieve excellent mechanical strength.
● Bending elastic modulus (normal temperature, absolute dry state)
● E series (E440N)=14,600Mpa
● A series (A350)=17,000Mpa
● Liquidity: have good liquidity.
● Chemical resistance: Demonstrates the best chemical resistance among polyamides.
● High temperature rigidity: With a high glass transition temperature of 125℃, it can maintain high rigidity even in the high temperature environment of the engine room.
