Polyetherimide (PEI)
Description (definition)
Polyetherimide (PEI) is an amorphous, high-performance thermoplastic characterized by its high strength, temperature resistance and chemical stability. PEI is a preferred material in industries such as automotive, electronics and household appliances as it remains reliable even under high temperatures and stresses. It is also valued for its good electrical insulation and flame retardancy rating.
Example
A typical example is the use of PEI in connectors and housings in the electronics industry. Its high heat resistance and electrical insulation make it ideal for demanding applications in high-performance electronics.
Why is PEI so popular in the automotive industry?
PEI is used in the automotive industry for components such as lamp housings, sensor covers and connectors. Thanks to its high temperature and flame resistance, it is particularly suitable for engine compartment parts that are exposed to constant stress.
What advantages does PEI offer in the electrical industry?
PEI provides excellent electrical insulation and is flame retardant, making it a safe and reliable material for sockets, switches and other electrical components. Its stability at high temperatures ensures a long service life in demanding environments.
How is PEI used in household appliances?
In household appliances, PEI is used in components that require heat resistance and robustness, such as in coffee machines, microwave components or steam valves. It combines durability and safety and contributes to the efficiency of modern appliances.
