KINGFA LONOY-1200

Product Overview

Kingfa LONOY-1200 is a high-performance PC+PBT alloy engineered for applications requiring exceptional impact strength, chemical resistance and weatherability.
Its high flow characteristics and balanced mechanical–thermal–electrical performance make it an excellent choice for appliances, business equipment, outdoor housings, and durable injection-molded components exposed to long-term environmental stress.

This material combines the toughness of polycarbonate with the chemical resistance and dimensional stability of PBT—offering a robust solution for demanding consumer and industrial products.
