Mitsui Arlen™ A350 50% Glass Fiber-Reinforced Modified Nylon 6T (DAM)
Categories:	Polymer; Thermoplastic; Nylon (Polyamide PA)
Material Notes:	ARLEN™ is a heat resistant, modified polyamide 6T developed by Mitsui Chemicals, Inc. With a high melting point (320°C) and a rigidity level comparable to super engineering plastics, it possesses strong dimensional stability and chemical resistance. In addition, the effect of water absorption, which is a traditional weakness of polyamides, has been reduced to a minimum. Applications: Cylinder head covers Thermostat cases Oil pump housings Hydraulic system pistons Cooling system parts Roller/pulley parts Information provided by Mitsui.
