Polyphenylene Ether Sheets Polyphenylene Ether Sheets Polyphenylene Ether Sheets
Polyphenylenether / PPE Sheets
Our Polyphenylenether (PPE) sheets are a remarkable amorphous material offering exceptional properties. They exhibit minimal moisture absorption, outstanding dimensional stability, and remarkable impact strength.
PPE sheets demonstrate an impressively low moisture absorption rate, making them an ideal choice for insulation in a wide range of temperature and humidity conditions. Their unique alloy composition enables electroplating, thanks to their strong electrical characteristics.
These polymer sheets, often referred to as PPO, showcase outstanding mechanical, dimensional, and heat-resistant characteristics. They can also be engineered to be flame-resistant and possess excellent hydrolysis resistance with reduced moisture absorption.
PPE sheets find extensive applications in the electrical equipment industry, serving as crucial components in connectors, circuit breakers, vending machines, and water softeners. Additionally, they are used in various printer and copier components, often blended with PS or nylon to enhance processability.
