How to improve the mechanical properties of PBT raw materials

In the field of modern materials science, polybutylene terephthalate (PBT) is widely used due to its excellent mechanical properties. However, for specific industrial needs, a single PBT material may not meet the requirements of practical applications in terms of strength, toughness and hardness. Therefore, modifying PBT to improve its mechanical properties has become an important topic in the industry. As an inorganic compound, magnesium oxide has unique physical and chemical properties, making it a key additive to improve the performance of PBT.

The addition of magnesium oxide significantly enhances the flame retardant properties of PBT. PBT is flammable and easy to decompose in high temperature environments, while the introduction of magnesium oxide can form a protective barrier during the combustion process, effectively isolating oxygen, slowing down the combustion rate, and even causing the flame to self-extinguish in some cases. This feature is particularly important in key applications such as charging equipment for new energy vehicles. It not only significantly improves the safety of the product, but also ensures the stability and smoothness of the charging process.

In terms of weather resistance, magnesium oxide also exhibits excellent performance. In outdoor environments, plastic materials are often eroded by natural factors such as sunlight, rain, wind and sand, leading to aging and cracking of the materials. The addition of magnesium oxide can effectively prevent the intrusion of oxygen, thereby inhibiting the oxidation and aging of the material and significantly extending the service life of PBT. This makes the modified PBT show wide application potential in outdoor lighting, building exterior walls and other fields, meeting the dual needs of modern architecture and environmental aesthetics.

In addition to flame retardancy and weather resistance, the improvement of mechanical properties of PBT by magnesium oxide cannot be ignored. In the demanding field of electronics and electrical, the use of high-purity magnesium oxide can ensure the electrical properties and flame retardant properties of the material; in the automotive industry, magnesium oxide with good dispersibility and wear resistance significantly improves the mechanical properties of the material. Strength and durability. The introduction of magnesium oxide not only enhances the hardness and wear resistance of PBT, making it more resilient when subjected to external forces and reducing the risk of breakage, but also improves its impact resistance, ensuring that the material can maintain good structural integrity, further extending its service life.
