Designed to Thrive Where Only the Strong Survive

Amodel® polyphthalamide (PPA) is a family of high-temperature polyamides that retain their high strength and stiffness up to 280°C. They maintain mechanical integrity after thousands of hours at elevated temperatures and in high humidity and chemically aggressive environments.

With a high melting point over 300°C, Amodel® PPA enables electronic processes and assembly including surface mount technology (SMT), IR reflow soldering, and overmolding of metals.

 

Distinctive Base Resins

Products in the Amodel® PPA portfolio are based on one of five different base resins, each offering distinct product and processing characteristics. Our new Amodel® Supreme PPA products are based on our new 9000 Series base resin.

Market Applications

For over 25 years, Amodel® has been used in automotive, electronics, consumer, and industrial applications. Amodel® has a long history of replacing metals (die cast Al and Mg) in a range of automotive applications, including thermostat housings, clutch cylinders, charge air coolers, heater cores and water pumps. Select grades with food contact and drinking water approval have enabled metal replacement in small appliances and plumbing components.
