DuPont Boosts PPA Capacity
Supporting demand in automotive and consumer electronics.
DuPont Performance Polymers, Wilmington, Del., has increased production of its Zytel HTN polyphthalamide (PPA) at its Richmond, Va., facility by 10% to meet growing global market demand in automotive and consumer electronics. Demand is growing in automotive because the material can stand up to long-term exposure to heat and chemicals in underhood and powertrain components. In electronics and hand-held devices, Zytel HTN offers dimensional stability and ability to withstand lead-free soldering.
Helping electronics, lighting, and car engines keep cool are some new roles for hermoplastics that are formulated to replace metal or ceramic.
The degree to which molded parts shrink as they cool is largely dependent upon the composition of the material being processed.
In the first three parts of this series we focused on those influences that cause molded parts to get smaller. But there are environmental factors that also cause parts to increase in size over time.
