I. Composition

PEI LCF20 is a thermoplastic composite material. It uses polyetherimide as the base material and adds long carbon fibers with a mass percentage of 20% as the filling material for enhanced modification. This unique combination endows the material with excellent performance.

II. Performance Characteristics

1. High strength and rigidity: The addition of carbon fiber makes PEI LCF20 have extremely high strength and rigidity. It can withstand huge external forces without deformation and maintain a stable structure in various harsh environments.
2. Good heat resistance: This material has excellent heat resistance and can work stably for a long time in high temperature environments. Even at a temperature as high as 250°C, PEI LCF20 can still maintain the stability of its physical and chemical properties.
3. Chemical corrosion resistance: It has good tolerance to a variety of chemical substances. Whether it is strong acid, strong alkali or organic solvent, it is difficult to erode it.
4. Good dimensional stability: Under different temperature and humidity conditions, the dimensional change of PEI LCF20 is very small, which can ensure the accuracy and reliability of products.
5. Good flame retardancy: When encountering a fire source, PEI LCF20 can play a certain flame retardant role and reduce the risk of fire.
6. Low moisture absorption: This material has a very low absorption capacity for moisture and can maintain good performance in a humid environment.
7. Excellent wear resistance: PEI LCF20 has excellent wear resistance and can maintain a smooth and intact surface during long-term use.
8. Good processing performance: It can be molded by various processing methods such as injection molding and extrusion, which is convenient for producing products with various complex shapes.

III. Application Fields

Due to its excellent performance, PEI LCF20 composite material has a wide range of applications in fields such as aerospace, automobile manufacturing, and electronics. In the aerospace field, it can be used to manufacture aircraft parts such as wings and fuselages; in the automobile manufacturing field, it can be used to manufacture engine parts and transmission systems; in the electronics field, it can be used to manufacture high-performance electronic product casings.

IV. Application Case

As the manufacturer of PEI LCF20 composite material, Carbon (Xiamen) New Material has successfully applied this material to the manufacturing of the casing of a high-end medical device. This medical device has very high requirements for the casing. It not only needs to have high strength and rigidity to protect the internal precision electronic components and medical parts, but also needs good heat resistance and chemical corrosion resistance to adapt to various complex medical environments.

PEI LCF20 composite material just meets these requirements. Its high strength and rigidity enable the casing to effectively resist external impacts and collisions and protect the safety of internal equipment. Good heat resistance ensures that the casing will not deform or be damaged during high-temperature disinfection. At the same time, chemical corrosion resistance enables the casing to resist the erosion of various disinfectants and cleaners and maintain long-term stability.

To verify the performance of this material, Carbon (Xiamen) New Material has conducted a series of strict tests. In the strength test, the casing is dropped freely from a certain height multiple times. After repeated tests, the casing still remains intact without obvious damage or deformation. In the heat resistance test, the casing is placed in a high-temperature environment for a period of time. After taking it out and observing, the shape and performance of the casing have not changed. In the chemical corrosion resistance test, the casing is soaked in various chemical reagents. After a period of time, there is no corrosion phenomenon on the surface of the casing.

It can be seen through this application case, that PEI LCF20 composite material shows great application potential in the field of high-end medical devices with its excellent performance. Carbon (Xiamen) New Material will continue to be committed to researching and producing high-performance composite materials and providing strong support for the development of various fields.
