why polypropylene has good heat resistance

Polypropylene (PP) has good heat resistance. The heat deformation temperature of PP material is around 120°C, which is higher than many common raw materials. This is mainly due to its molecular structure and special chemical properties. The following is the reason why PP has good temperature resistance summarized by the editor of Qingdao prime union：

1.High melting point: Polypropylene has a relatively high melting point, generally between 130°C and 171°C, which allows it to maintain structural stability in high-temperature environments.

2.Crystallization properties: Polypropylene is a semi-crystalline polymer with a high degree of crystallinity. High crystallinity means a more orderly arrangement of molecules, which helps improve the material's stability and heat resistance;

3. Thermal stability: There are no phenolic groups or other functional groups susceptible to thermal degradation in the molecular structure of polypropylene. Therefore, it is not prone to decomposition or degradation reactions at high temperatures.

4. Not sensitive to heat: Polypropylene is not sensitive to most chemicals, which makes it more stable under high temperatures or special environments.

However, in order to further improve the performance of PP, material scientists began to study the effect of adding talc powder to polypropylene. PP materials are modified and processed to add a certain proportion of fillers. Taking PP+30% talcum powder filling as an example, the temperature resistance is improved to about 145°C. The excellent characteristics of PP make it an ideal choice for many applications, such as electric heating appliances, electric heating equipment, air conditioning outlets, automobile parts, etc. So besides that, what other properties does PP+30% talc powder improve?

1. Improvement of mechanical properties: The hardness and compressive strength of talc provide significant enhancement to polypropylene. This blend has greater strength and stiffness, making it better suited for structural applications.

2. Increased wear resistance: The addition of talc powder improves the wear resistance of the material, making it more durable in friction and wear environments, and is suitable for applications requiring high wear resistance.

3. Reduce density: The low density characteristics of talc powder help reduce the overall weight of the material, which has significant advantages for some fields that focus on lightweight design, such as automobiles and aerospace.

4. Improve thermal stability: Talc powder has good thermal conductivity and can improve the thermal stability of polypropylene, making it more suitable for high temperature environments.

With the continuous improvement of materials, PP+talcum powder materials are often used in the industries around us. It is often used in the following industries:

1. Automobile industry: PP + 30% talc powder mixture can be used to manufacture automobile parts, such as body components, interior parts and engine parts, to improve the performance and durability of automobiles.

2. Building materials: Due to its improved strength and wear resistance, this new material is suitable for use in the construction field and is used to manufacture structural parts, pipes and floor materials.

3. Packaging industry: The introduction of PP + 30% talcum powder mixture into packaging materials can improve the strength and durability of the packaging while reducing the overall weight of the packaging.

4. Electronic products: Due to its improved thermal stability, it can be used in areas such as electronic product casings that require high temperature resistance.
