TECHNOMELT PA 678 (e) high performance thermoplastic polyamide
is designed to meet low pressure molding process requirements. This
product can be processed at low processing pressure due to its low
viscosity, allowing encapsulation of fragile components without
damage. This material produces no toxic fumes in process and
provides a good balance of low and high temperature performance.
