Polyphenylene ether
Polyphenylene ether (PPO), also known as polyphenylene ether b in Chinese, is one of the five general-purpose engineering plastics in the world. It has the advantages of high rigidity, high heat resistance, flame retardant, high strength and excellent electrical properties. In addition, PPO also has the advantages of wear resistance, non-toxicity and pollution resistance. The dielectric constant and dielectric loss of PPO are one of the smallest varieties among engineering plastics, and they are hardly affected by temperature and humidity. It can be used in the fields of low, medium and high frequency electric fields (the smaller the dielectric constant, the better the insulation). The load deformation temperature of PPO can reach above 190°C, and the desalination temperature is -170°C. (PPO or PPE) is also called polyphenylene oxide, and its chemical name is poly 2,6-dimethyl-1,4-phenylene ether. It is a linear polymer made of 2,6-dimethylphenol through oxygen and oxidative condensation reaction under the action of a catalyst.
Generally in the form of khaki powder. The commonly used polyphenylene ether is synthesized from 2,6-dimethylphenol, which has excellent comprehensive properties. The biggest feature is that it has excellent dimensional stability and outstanding electrical insulation under long-term load, and it has a wide range of operating temperatures. , can be used for a long time in the range of -127 ~ 121 ℃. It has excellent water resistance and steam resistance, and the products have high tensile strength and impact strength, and good creep resistance. In addition, it has good wear resistance and electrical properties.
Material Properties
1. It is white particles. Good overall performance, can be used in steam at 120 degrees, good electrical insulation, small water absorption, but tends to stress cracking. Modified polyphenylene ether eliminates stress cracking.
2. It has outstanding electrical insulation, excellent water resistance, and good dimensional stability. Its dielectric properties rank first among plastics.
3. MPPO is a modified material made by blending PPO and HIPS. The materials currently on the market are all this kind of material.
4. It has high heat resistance, the glass transition temperature is 211 degrees, the melting point is 268 degrees, and it has a tendency to decompose when heated to 330 degrees. The higher the PPO content, the better the heat resistance, and the heat distortion temperature can reach 190 degrees. .
5. Good flame retardancy, self-extinguishing, moderate flammability after mixing with HIPS. Lightweight, non-toxic and can be used in food and pharmaceutical industries. The light resistance is poor, and it will change color 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.
Purpose
1. It is suitable for making heat-resistant parts, insulating parts, wear-reducing and wear-resistant parts, transmission parts, medical and electronic parts.
2. It can be used as gears, fan blades, valves and other parts used at higher temperatures, and can replace stainless steel.
3. Can make screws, fasteners and connectors.
4. Electrical parts of motors, rotors, casings, and transformers.
5. PPO and MPPO are mainly used in electronic appliances, automobiles, household appliances, office equipment and industrial machinery, etc., using MPPO for heat resistance, impact resistance, dimensional stability, scratch resistance, and peeling resistance.
6. Paintability and electrical properties, used for automotive dashboards, radiator grilles, speaker grilles, consoles, fuse boxes, relay boxes, connectors, and wheel covers.
