Base Resins

How We Make the Amodel® PPA Grades

Our polyphthalamide 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.

Standard Glass Fiber Reinforced Grades

Glass fibers boost strength and stiffness, while enhancing short-term thermal properties as well as long-term resistance to creep and fatigue. For applications requiring wall thickness greater than 3 mm (0.125 in.), consider one our AS grades.

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.
