Their buying rationale is dominated by the need for lightweighting, enhanced crash performance, dimensional stability under varying temperatures, and resistance to aggressive fluids like brake fluid and gasoline, making PBT/PC blends particularly attractive for these demanding uses.
Another major segment comprises manufacturers of Electrical and Electronics (E&E) components, including producers of circuit protection devices, connectors, relays, and power supply housings. These customers prioritize alloys with exceptional dielectric strength, high comparative tracking index (CTI), and inherent flame retardancy to meet rigorous electrical safety standards (e.g., IEC and UL certifications). The miniaturization trend in electronics necessitates materials that can be precisely molded while maintaining strength and heat dissipation capabilities, leading them to favor high-flow, reinforced thermoplastic polyester alloys that ensure reliable long-term performance in confined spaces.
Beyond the core automotive and E&E industries, potential customers include manufacturers of high-end Consumer Goods, particularly those producing durable appliances, power tools, and complex filtration systems. These buyers seek materials that combine aesthetic appeal, ergonomic design capabilities, chemical resistance to cleaning agents, and resilience against repeated impact and wear. The rationale here is maximizing product lifespan and minimizing warranty claims through the use of robust engineering polymers. Additionally, the growing medical device sector, requiring biocompatibility and sterilizability, presents a specialized customer segment for highly certified and traceable thermoplastic polyester alloys used in instrument handles and specialized medical housings.
