Polyphthalamide PPA resin Introduction
Outperforms standard polyamides in heat, moisture and chemical resistance
Semi-crystalline polyphthalamide is a high performance polyamide with outstanding high heat, hydrolysis and chemical resistance, and electrical properties.
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.
Polyphthalamide PPA resin Properties
Higher Heat Resistance
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. PPA’s lower water absorption rate results in significantly less change in strength and stiffness, even with high levels of humidity.
Better Chemical Resistance
PPA’s highly aromatic ring structure provides greater resistance to a broader range of chemicals than standard aliphatic polyamides, even at high temperatures. This enables automotive, electrical and industrial components to withstand prolonged exposure to harsh chemicals:
Bio-diesel fuel
Brake fluid
Calcium chloride
Glycols
Synthetic motor oil
Road salt
Sulfuric acid
Transmission fluid
Zinc chloride
Polyphthalamide PPA resin Application
Polyphthalamides (PPA) outperform 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.
With a heat deflection temperature of 280°C (536°F) and continuous-use temperature up to 210°C (410°F), PPA (polyphthalamide) can take the heat in under-the-hood applications that are too demanding for conventional nylons and polyesters.
