Mitsui Arlen™ A350 50% Glass Fiber-Reinforced Modified Nylon 6T (COND)

Subcategory: Filled/Reinforced Thermoplastic; Nylon; Polymer; Thermoplastic

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
