Controlled Crystallization Polyamide to Eliminate Paint

In order to support greater design freedom for any shape and length register vanes while meeting stiffness, durability, and perceived quality requirements, a partially aromatic injection-molded PA 6/6 / 6I resin was used to boost modulus without increasing wall thickness or adding glass reinforcement to achieve a high-quality, MIC Class A surface without paint.  Owing to the "kinked" crystalline structure of the semi-aromatic PA resin, crystallization rate can be better controlled, so parts fully pack out before skins freeze off, leading to a resin-rich surface with a smoother surface and better appearance, eliminating the need to paint.
