Amodel A-1933 HSL
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.
Amodel PPA outperforms standard polyamides with higher strength and stiffness at elevated temperatures, better retention of properties in humid environments, and greater resistance to a broader range of chemicals.
Higher Heat Resistance
Amodel PPA is used to replace metal in high-temperature automotive applications. Continuous-use temperatures range from 120°C to 185°C (248°F to 365°F). Heat deflection temperatures (HDT) go up to 310°C (590°F).
Lower Moisture Absorption
Humid environments can have a devastating effect on the mechanical properties of standard polyamides. Amodel PPA’s lower water absorption rate results in significantly less change in strength and stiffness, even with high levels of humidity.
Better Chemical Resistance
Amodel PPA’s highly aromatic ring structure provides greater resistance to a broader range of chemicals than standard aliphatic polyamides, even at high temperatures.
