ARLEN™ A315 by Mitsui Chemicals is a modified polyamide 6T reinforced with 15% glass fiber. Possesses high dimensional stability, high melting point (320°C), minimum water absorption and high glass transition point (125°C). Exhibits good chemical and heat resistance. Offers high rigidity even in a high-temperature atmosphere such as the inside of an engine room. Is suitable for processing by injection molding. ARLEN™ A315 is used in mechanical and structural applications including under the hood parts such as cooling system parts, cylinder head covers, thermostat cases, hydraulic system pistons and oil pump housings. Recommended for light-load tribological application parts of office automation equipment. Complies with UL 94 HB flame rating.
