PPA Amodel A-1933 HSL
Material Notes: | Amodel? A-1933 HSL is a 33% glass reinforced grade of polyphthalamide (PPA) resin. This grade was developed specifically for improved performance in a 50/50 ethylene glycol and water environment. This material was tested using the aggressive automotive coolant system, ethylene glycol with organic acid stabilizer, at 130°C (266°F). It exceeds the performance required by the automotive industry for polymeric materials exposed to high-temperature antifreeze solutions. Potential applications include a variety of automotive components such as thermostat housings, heater core endcaps, heater hose connectors, and water inlets, outlets, and valves. Key Attributes: Antifreeze Resistant; Chemical Resistant; Creep Resistant; Good Dimensional Stability; Good Glycol Resistance; Good Stiffness; High Heat Resistance; High Strength; Lubricated Applications: Automotive Applications; Automotive Under the Hood; Housings; Valves/Valve Parts Automotive Specifications: ASTM D6779 PA131G35 Color: BK328 Black; CHRYSLER MS-DB-478 CPN4771 Color: BK328 Black; GM GMP.PPA.019 Color: BK328 Black; GM GMW16360P-PPA-GF35 Color: BK328 Black; ISO 1874-PA6T/6I, MH, 11-120, GF33 Color: BK-328 Black; ISO 1874-PA6T/6I, MH, 11-120, GF33 Color: NT-07 Natural Injection Notes: Mold Temperature: Storage: |
