The port cover of automotive high voltage line junction box was originally used as TPV N1090AN in red and black, and main specifications are fine.
TPV N1090AN is an off-white general purpose thermoplastic rubber. It is not flame retardant, but has good plasticizing properties. The figure shows product obtained after addition of black masterbatch, appearance of which is very good.
When a customer requested a flame retardant, Mite recommended TPV 8185AN-G flame retardant. Because buyer needs red and black, he specially sent white 8185AN-G to buyer, and customer added Mother black, and finally found that injection molded product had black masterbatch dispersion problem.
In this picture, black masterbatch is clearly poorly dispersed in flame retardant TFE, so I'm planning to ship 8185AB-G black flame retardant TFE to customer, but headache is that flame retardant TFE company does not match other colors, red. Customers still need to find a way!
