Polyphenylene Oxide (PPO) is renowned for its outstanding thermal stability, dimensional stability, and electrical insulating properties. This high-performance engineering plastic is often blended with high-impact polystyrene (HIPS) to enhance its processability and mechanical properties. The blend, commonly known as Noryl, exhibits a unique balance of strength, rigidity, and heat resistance, making it a preferred choice in demanding engineering applications.
