the active actions of various countries in the fields of recycled plastics and new energy reflect the global high attention to environmental protection and sustainable development. In the new energy field, Japan and South Korea promote the development of the electric vehicle battery industry through measures such as subsidies and strengthened supervision, laying a solid foundation for reducing carbon emissions and realizing energy transformation. In the field of recycled plastics, the innovative practices of Thailand and Dow provide feasible solutions for reducing plastic pollution and realizing resource recycling. In the future, with the continuous attention and investment of various countries in environmental protection and sustainable development, the fields of recycled plastics and new energy will surely usher in a broader development space.

Market concerns about the risk of the Iran-Israel conflict have somewhat subsided, coupled with the International Energy Agency's downward revision of the global demand growth forecast, international oil prices have declined.

DC fans generally use black modified PBT as the material for the outer frame and fan blades, and it is usually applied in the form of 30% fiber addition, which can make the fan heat-resistant, flame-retardant, insulating and have sufficient mechanical strength.

In practical applications, PBT materials may be used in internal structural components, shells, and other parts of air fryers. But it should be noted that PBT also has some disadvantages, such as low notch impact strength and large molding shrinkage rate. Therefore, methods such as glass fiber reinforcement or inorganic filling modification are usually adopted to improve its performance. At the same time, the specific application of PBT materials also needs to follow relevant production standards and safety regulations to ensure the quality and safe use of air fryers.

The application and advantages analysis of PBT in the field of hair straighteners, and its future development trends.Some application examples of PBT materials in the field of hair straighteners are as follows
