In terms of processing, PBT generally requires higher injection pressures and temperatures compared to PC. This is because PBT has a higher melting point and viscosity. PC, on the other hand, is more amenable to cold成型 processes and has a lower melt viscosity, allowing for easier molding at lower temperatures.
综合特性PC/PBT is a plastic alloy that combines the advantages of both materials. It retains PBT's chemical stability and ease of molding while inheriting PC's toughness and dimensionally stable properties. PC/PBT offers a balance between surface hardness, rigidity, and韧性, as well as improved resistance to stress cracking and high temperatures. This makes it suitable for applications requiring large-scale exterior components.
价格和市场接受度When it comes to price and market acceptance, these factors can vary depending on the specific application and end-user requirements. Both PBT and PC have their own set of customers who value different properties over others. For example, PBT may be preferred for its stiffness and耐热 properties in automotive applications, while PC may be favored for its transparency and impact resistance in consumer electronics.
In conclusion, the choice between PBT and PC depends on the specific needs of the application. If high stiffness and thermal stability are crucial, PBT would be the better option. However, if impact resistance, transparency, or ease of molding are more important, PC might be the preferred material. It is essential to consider the specific requirements of the project and choose the plastic that best meets those needs。
