Syensqo (Solvay Specialty Polymers) Amodel® A-1945 HSL Polyphthalamide (PPA) (discontinued **)
Categories:	Polymer; Thermoplastic; Polyphthalamide (PPA); Polyphthalamide (PPA), 50% Glass Fiber Reinforced
Material Notes:	Amodel A-1945 HSL is a 45% 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 antifreeze. Potential applications include a variety of automotive components such as thermostat housings, heater core endcaps, heater hose connectors, and water inlets, outlets, and valves. - Black: A-1945 HSL BK 328 Information provided by Solvay Specialty Polymers.
