PEI CF (carbon fiber reinforced PEI resins) is an advanced material composed of a polyetherimide (PEI) matrix and carbon fiber. PEI itself has excellent high-temperature resistance, mechanical strength, and chemical stability. When combined with carbon fiber, the performance of this composite material is greatly enhanced. It has higher strength and rigidity while maintaining good heat resistance and dimensional stability. 

And PEI-CF60 is further developed on the basis of PEI CF. The “60” in it usually represents a relatively high content ratio of carbon fiber, which may reach 60%. Compared with ordinary PEI CF, PEI CF 60 has more excellent mechanical properties. Due to the increase in carbon fiber content, its strength, rigidity, and heat resistance are significantly improved. In some application scenarios with extremely demanding material performance, such as high-end aerospace components and high-performance racing car parts, CF60-PEI shows great advantages.

PEI CF60 can be regarded as an upgraded version of PEI CF. Together, they provide strong impetus and more choices for the development of high-performance materials and meet the needs of different fields for advanced composite materials.

What does PEI CF 60 Feature?

PEI CF60 (carbon fiber reinforced polyetherimide, and the carbon fiber content may be 60%). The main characteristics are as follows:
1. Excellent mechanical properties:
– High strength. After being reinforced by carbon fiber, it can withstand high stress and load, and is suitable for high-strength structural parts. Products: high-performance mechanical transmission parts, aerospace structural parts.
– High rigidity. It is not easy to deform under stress and maintains dimensional stability and shape accuracy. Products: precision instrument casings, high-end sports equipment parts.
2. Outstanding heat resistance:
– High temperature resistance. Inheriting the characteristics of PEI and further improving thermal stability, it is suitable for parts under high temperature working conditions. Products: automotive engine peripheral parts, industrial high-temperature equipment parts.
– Low coefficient of thermal expansion. The size changes little when the temperature changes. Products: optical instrument parts, high-precision measuring tools.
3. Good flame retardancy: Maintaining the inherent flame retardancy of PEI and preventing the spread of flame, which is in line with scenarios with high flame retardancy requirements. Products: electronic equipment casings, electrical control cabinet parts.
4. Superior electrical properties: Good electrical insulation and dielectric properties, and has application advantages in the electronic and electrical fields. Products: electronic component casings, electrical insulation parts.
5. Chemical resistance: Resistant to a variety of chemical substances and is used for parts in corrosive environments. Products: chemical equipment parts, pharmaceutical machinery parts.
6. Certain processability: It can be processed by molding processes, but the difficulty is increased compared to pure PEI. Products: small complex structural parts, customized industrial accessories.
