PPE (Polyphenylene Ether)
Description (definition)
Polyphenylene Ether (PPE) is an engineering amorphous plastic characterized by high heat resistance, excellent electrical insulation properties and low water absorption. PPE is chemically resistant and has good dimensional stability, making it ideal for applications in the electrical, electronics and automotive industries. PPE is often used as a blend with polystyrene (PS) to improve processability and mechanical properties.
Example
A typical example is the use of PPE in housings for electrical equipment. The excellent insulation and resistance to high temperatures ensure safe and durable applications.
What advantages does PPE offer over other plastics?
PPE combines exceptional electrical insulating properties with chemical resistance and dimensional stability. Compared to many other plastics, it hardly absorbs any moisture and retains its shape even in damp conditions.
In which applications is PPE preferred?
PPE is frequently used in the electrical and electronics industry for connectors, switch housings and transformer parts. It is also used in automotive components such as air ducts and in industry for pump housings.
Is PPE recyclable?
Yes, PPE is recyclable, especially when processed as a blend with polystyrene (PS). Recycled PPE is often used in less demanding applications, such as housings or technical components.
