Amodel polyphthalamide (PPA) is a family of high-temperature polyamides that retain their high strength and stiffness up to 280°C and maintain mechanical integrity after thousands of hours at elevated temperatures. Their low moisture absorption prevents blistering during IR soldering. These materials are highly resistant to many commonly used electronic cleaning agents, fuels, automotive fluids and road salts. Fast cycle times can lower molding costs.

Amodel resins are available in an wide variety of grades—including high strength, toughened, conductive, high flow, laser welding and flame retardant grades—giving you more ways to optimize performance, processing and price.

Xydar liquid crystal polymer (LCP) is a highly crystalline glass-filled resin that offers exceptional flow properties. It can withstand SMT assembly, including lead-free solder reflow, and retains its high strength and stiffness up to 300°C

Lower moisture prevents blistering
Blistering is primarily caused by water vaporizing during SMT processing. Amodel PPA absorbs significantly less moisture than conventional nylons and other high-temperature nylons, making it an excellent candidate for SMT processing up to 280°C.

Mechanical properties and cycle times
Materials like PPS may pass solder dip tests, but lack the tensile and flexural properties required for many electronics applications. Amodel PPA delivers strength, toughness and impact resistance along with low moisture absorption, high HDT and faster injection molding cycle times.
