Amodel® PPA Outperforms Typical Nylons
Compared to typical nylons, Amodel® PPA has higher thermal capabilities and is stronger, stiffer and less sensitive to moisture. It retains its excellent mechanical properties – including fatigue and creep resistance – over a broad temperature range in humid and chemically aggressive environments.
Key Features
- Higher strength and stiffness at elevated temperatures
- Better retention of mechanical properties in high humidity
- Greater resistance to a broader range of chemicals
High HeatAmodel® PPA Really Takes the Heat
Amodel® PPA boasts heat deflection temperatures (HDT) to 310°C (590°F), making it possible to withstand the high reflow temperatures of SMT processing without blistering or warping.
Continuous-use temperatures from 120-185°C (248-365°F) make Amodel® resin a reliable choice for demanding under-the-hood automotive components.
Effects of MoistureRetains Mechanical Properties in Humid Environments
Humid environments can have a devastating effect on the mechanical properties of typical nylons. Amodel® PPA’s lower water absorption results in significantly better retention of strength and stiffness properties, even with high levels of humidity.
Chemical ResistanceResistance to a Broad Range of Chemicals
Amodel® PPA’s highly aromatic ring structure provides greater resistance to more chemicals than typical nylons, even at high temperatures. This allows it to be used in demanding automotive and industrial applications where it must withstand prolonged exposure to aggressive chemicals, such as:
- Bio-diesel fuel
- Brake fluid
- Calcium chloride
- Glycols
- Synthetic motor oil
- Road salt
- Sulfuric acid
- Transmission fluid
- Zinc chloride
Amodel® PPA Grades
Amodel® PPA is available in a breadth of grades unequaled in the industry. A side-by-side comparison of typical properties provides a quick overview of performance capabilities. Individual data sheets are also available.
How We Make the Grades
Amodel® PPA products are based primarily on three semi-aromatic, semi-crystalline polyamide base resins, with each offering distinct performance and processing characteristics.
Glass fibers, heat stabilizers, impact modifiers, minerals and other materials are compounded with these base resins to create a comprehensive selection of Amodel® PPA products for use in a vast array of applications.

Mineral and Mineral/Glass Fiber Reinforced Grades
Minerals reduce warpage and differential shrinkage by disrupting the orientation of the glass fiber. This results in more uniform shrinkage and improves dimensional stability. Coefficient of Linear Thermal Expansion
