Injection Molding Technology: The high glass reinforced Zytel® contains superior flow properties without sacrificing the mechanical properties like elongation or impact. It offers significant advantages to the user, as demonstrated in the article.
Sensors and actuators used in the engine compartment are being exposed to higher temperatures, more aggressive media and more extreme thermomechanical loads than ever before. These combined stresses are imposing requirements that increasingly exceed the capabilities of the polymers traditionally used to encapsulate and mount electronic components. In such cases, switching to engineering polymers that offer higher performance can provide a cost-effective solution.
Because they maintain excellent strength and toughness during exposure to hot, aggressive automotive fluids and to hot air whether humid or dry, high performance polyamides (HPPA) can make durable, functional components for automotive thermal management and other demanding applications. This paper reviews the basic chemistry of polyamides and demonstrates how the HPPA family differs from standard nylon. It focuses on semi-aromatic HPPA polymers known as polyphthalamides (PPA).
