Good heat resistance, PPO/PS alloy can replace PET and exothermic coating of the cardboard. PPO/EPS alloy can be molded into a wall, floor and floor substrate. PPO/HIPS alloy in market mainly for the production of office furniture and airport with furniture, such as your armrest; In the field of health care, can produce portable oxygen, blood analyzer and other inspection equipment shell. Injection molding feedstock PPO alloy can also in the automotive, construction, furniture and high temperature applications play a role in packaging industry, manufacturing, including hot water pipe, pipe insulation, heat sink jacket insulation parts, heating and air-conditioning equipment, etc.

modified PPO is mainly used in automobile, office equipment, telecommunications, electrical and electronic, mechanical, and other fields. Most modified PPO in PPO alloy consumption, accounting for 99% of the plastic PPO are above. In the United States, the application of PPO alloy with mechanical appliances for many, the second is the transport machinery, office equipment and electrical/electronic equipment. In Europe, is mainly used for automobile, accounts for about 1/3 of the total demand.

split between electronic parts use and industrial use, two kinds of modified modified PPO application in household electronic electrical components including radio, television, animation stereo components, speakers, telephone and smoke detector parts of wiring devices, etc. In office equipment, PPO/PS alloy were dominant, it is because he has a high flame retardant animation formability and strength, etc. Modified PPO in office equipment is mainly used in computer, etc.

Japan is mainly used in office equipment, accounted for 48%, followed by the auto industry, accounting for 28%, 20% fall in electrical/electronic. PPO alloy, the application is very wide, consumption is a lot of PPO/PS alloy, followed by PPO/PA alloy, other varieties quantity is less, the production scale is not big. Modified PPO in the car can be used against heat resistance, flame retardancy, electric properties, impact performance, dimensional stability, high mechanical strength requirements of auto parts, such as PPO/PS alloy is suitable for humid, load and high requirements for electrical insulating and good dimensional stability, is suitable for manufacturing auto wheel cover, the rear-view mirror frame, grille, etc.

PPO/PA alloy with excellent mechanical properties, dimension stability, oil resistance, electric insulation, impact resistance, can be used for making automobile external parts, such as a large shield, after, wheel cover, cushion choke plate, etc. Higher requirements on the glass transition temperature of engine hood is PPO/PA alloy application direction in the future. PPO/PBT alloy thermal deformation temperature is high, its sensitivity to moisture is small, is an ideal material to make car plate.

the mold temperature on the injection molding processing products and quality has a great influence, adopt suitable mold temperature, can reduce the internal stress of products, improve product appearance, overcome the wrinkling on the surface of the insert around, if the mold temperature is low, more complex products and thin wall products molding difficult, and the products surface gloss, internal stress is large, but also the mold temperature is unfavorable and exorbitant, otherwise parts easy to deformation, sag, and extend the molding cycle, reduce the production efficiency. The enhancement grade of modified PPO mold temperature is 65 - For 80-80 ℃, the enhancement level 100℃。

PPO/PS alloy used for hot water and has low moisture absorption of fluid handling equipment. Glass fiber reinforced PPO/PS alloy, its strength has reached or exceeded the pig iron, aluminum and other materials, so in all kinds of mechanical equipment is widely used to replace metal manufacturing pump body, valve, etc. PPO alloy is novel is used in building materials market, can be used in the production of foam board, roof and floor materials. PPO and food-grade HIPS form of alloy, but make it foam plate, used in refrigerator and high-temperature microwave packaging container.
