Another example, compared with POK (polyketone): Advantages: The cost may be relatively low. Disadvantages: It may be inferior to POK in terms of impact strength, mechanical properties, dimensional stability, etc. For example, the impact strength of POK may be 230% higher than that of PBT black G0, and the dimensional stability of POK may also be stronger. Compared with nylon (polyamide), the wear resistance and strength of PBT may be slightly inferior, but the water absorption rate is lower. Compared with PC (polycarbonate), the transparency and impact strength of PBT may be inferior to PC, but it may have certain advantages in chemical resistance and molding processing. In conclusion, PBT black G0 has its own characteristics and application scope. When selecting, comprehensive consideration of the specific requirements, cost, performance and other factors of the product is required.

The mechanical properties of PBT are similar to those of PA (polyamide, nylon) and POM (polyoxymethylene), which means it performs well in terms of withstanding external forces, tensile resistance and compressive resistance. Its characteristics of a small friction coefficient and good self-lubrication enable it to reduce wear in moving parts, improve the service life and operating efficiency of the parts. Good thermal stability and chemical stability prevent PBT from changing its performance in high temperatures and various chemical environments. The excellent electrical insulation property enables it to provide reliable insulation protection in electrical components. PBT has high rigidity and hardness, and can withstand large loads without deformation. At the same time, it can also show good resistance when impacted and is not easy to break. High dimensional stability helps to ensure the precise dimensions of injection-molded parts and reduce errors. Good heat resistance allows it to work normally at high temperatures. Due to these advantages, PBT is generally applied to the decorative rings of headlamps and the brackets in adjustment devices. After modification, by combining PBT with ASA (acrylonitrile - styrene - acrylate copolymer) and adding glass fiber reinforcement, the performance of the material is further enhanced and can be used to make the shell of fog lamps. Such modification can enhance the strength, weather resistance and impact resistance of the material, better meeting the requirements of the fog lamp shell in complex usage environments. For example, the decorative rings of headlamps of some automotive brands have adopted PBT materials, ensuring stability and reliability during long-term use. In the application of fog lamp shells, the modified PBT material can withstand various tests such as vibrations, temperature changes and possible collisions during vehicle driving.
