Main properties, limits of use and application
Polyphenylene ether PPE alloys - economic aspects

The main properties of PPE/PS are as follows:

• dimensional stability ;

• resistance to hydrolysis ;

• Resistant to a wide range of temperatures, from - 55 °C to + 130 °C ;

• good mechanical properties, rigidity, impact resistance, scratch resistance ;

• natural self-extinguishing, without additives ;

• good electrical properties.

The limits of use of PPE/PS are as follows:

• low UV resistance ;

• poor resistance to aromatics, premium fuels and solvents ;

• coefficient of friction ;

• relative fragility in large...
