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.
| Base Resin | Description | Tg, °C (°F) | Tm, °C (°F) |
|---|---|---|---|
| 1000 Series | Best balance of performance and processability. High long-term thermal performance | 123 (253) | 313 (595) |
| 4000 Series Hot-water moldable | Fastest crystallization for very fast cycle times. Highest elongation. High flow HFZ grades available. | 100 (212) | 325 (617) |
| 6000 Series Hot-water moldable | Excellent processing and surface appearance. High elongation. Used when ease of processing is a critical factor. | 88 (190) | 310 (590) |
| 8000 Series | Better thermal performance and lower moisture absorption than 1000 Series products. | 130 (266) | 325 (617) |
| 9000 Series Amodel® Supreme | Industry’s highest Tg of 165°C. Higher mechanical performance between 140-200°C. Exceptional CTI, dielectric properties and volume resistivity. | 165 (320) | 325 (617) |
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. In Green Hydrogen applications, Amodel® PPA is ideal in fuel cell systems where the use of metals as a construction material is prohibitive. Typical applications include end plates for fuel cell stacks, as well as air management, hydrogen management and thermal management system components.
