Product Description
PPO (Polyphenylene Oxide), also known as PPE (Polyphenylene Ether), is a high-performance thermoplastic renowned for its exceptional dimensional stability, thermal resistance, and electrical insulation properties. Combining the rigidity of engineering plastics with the processability of thermoplastics, PPO excels in applications demanding precision, durability, and resistance to harsh environments. Ideal for automotive, electronics, and industrial sectors, PPO empowers innovation where consistency and longevity are critical.
Basic properties of polyphenylene ether
1. It is white particles. It has good comprehensive performance and can be used in 120-degree steam. It has good electrical insulation and low water absorption, but it has a tendency to stress cracking. Modified polyphenylene ether can eliminate stress cracking.
2. It has outstanding electrical insulation and excellent water resistance, good wear resistance and electrical properties, and good dimensional stability. Its dielectric properties rank first among plastics.
3. MPPO is a modified material made by blending PPO and HIPS. All materials on the market are of this type.
4. It has high heat resistance, a glass transition temperature of 211 degrees, a melting point of 268 degrees, and a tendency to decompose when heated to 330 degrees. The higher the PPO content, the better the heat resistance, and the heat deformation temperature can reach 190 degrees.
5. It has good flame retardancy, self-extinguishing properties, and has moderate flammability when mixed with HIPS. It is light and non-toxic and can be used in the food and pharmaceutical industries. It has poor light resistance and will discolor when used in the sun for a long time.
6. It can be blended and modified with ABS, HDPE, PPS, PA, HIPS, glass fiber, etc.
