Polyphenylene ether (PPE), also called polyphenylene oxide (PPO), is a high performance, rigid amorphous engineering thermoplastics. It has high strength and impact toughness, outstanding electrical properties, dimensional stability, mechanical and dielectric strength and good resistance to many chemicals, and moderately high heat distortion temperature. To improve melt processability and toughness, polystyrene is usually added to it.
- Excellent Resistant to steam, hot water, salt solutions, acids, bases, and mineral.
- Low Moisture Absorption due to its inherent chemical composition.
- Good Electrical Insulating Properties over a wide range of humidity and temperature ranges because of its extremely low water absorption.
