Vydyne® R550H NT453

Vydyne® R550H NT453 by Ascend Performance Materials is a general purpose, heat stabilized, polyamide 66 (PA 66) grade reinforced with 50% glass fiber. Shows high heat distortion temperature, better dimensional stability, good flow, mold release, high rigidity, strength, excellent knit-line strength and superior surface appearance. Exhibits good chemical-, creep-, fatigue-, hydrolysis-, gasoline-, hydraulic fluid- and solvent resistance. Designed to maximize the retention of physical properties when exposed to anti-freeze solutions at elevated temperatures and minimizes oxidative degradation. Suitable for processing by injection molding. Used in automotive clips, radiator end-tanks, parts of the air-conditioning, fuel distribution systems, electrical connectors, housings, bobbins, industrial applications such as gears, bearing shells and covers applications. Vydyne® R550H NT453 complies with ASTM D 4066 PA012G50, ASTM D 6779 PA012G50, EC 1935/2004, EU 10/2011, EU 2023/2006, UL File No. E70062, UL-94 (HB), 3M 11-0003-5762-1, CHRYSLER MS-DB-41 CPN1900 Color: Black, CHRYSLER MS-DB-41 CPN2043 Color: Natural, CHRYSLER MS-DB-41 CPN2727 Color: Black, CHRYSLER MS-DB-41 CPN4014 Color: 100% Color Match, FORD ESE-M4D287-A Color: Black, FORD ESE-M4D287-B, FORD ESE-M4D287-B Color: Black, FORD WSK-M4D663-A, FORD WSK-M4D663-A Color: Black, GM EDS-M-5165-02, GM GMP.PA66.013, GM GMP.PA66.013 Color: Black, GM GMP.PA66.054, GM GMP.PA66.054 Color: Black, GM GMW3038P-PA66-GF50H Color: Natural, SAE J1639 PA1116, SAE J1639 PA1116 Color: Black, TagAZ TAMS-8729-01 Automotive Specifications and FDA 21 CFR 177.1500 regulations.
