Its compressive strength ranges from 1200 to 16400 MPa. Its Izod Impact strength ranges from 3 to 6 J/cm. Its elongation at break ranges from 48 to 50 %. Its hardness ranges from 115 to 116 Rockwell R. Its specific gravity ranges from 1.04 to 1.1. Its coefficient of thermal expansion ranges from 38 to 70 x 10-6/°C. Its melting temperature ranges from 100 to 112 °C. Its molding pressure ranges from 12 to 20 MPa.
Polyphenylene Oxide, also known as PPO, is a thermoplastic polycondensate. The most common trade name is Ashley. low glass transition temp Although it resists many chemicals, it is easily attacked by some hydrocarbons. It has excellent dimensional stability, low moisture absorption, and high mechanical and dielectric strength. PPO is processable by conventional extrusion and injection molding equipment.
Other common Polyphenylene Oxide (PPO) include Alloy With Polystyrene PPO, Alloy With Polystyrene, Impact Modified PPO, Alloy With Polystyrene, 15% Glass Fiber Reinforced PPO, Alloy With Polystyrene, 20% Glass Fiber Reinforced PPO, Alloy With Polystyrene, 30% Glass Fiber Reinforced PPO, Alloy With Polystyrene, Mineral Filled PPO, Alloy With Polystyrene, 30% Graphite Fiber EMI Shielding (conductive) PPO, Alloy With Polystyrene, 40% Aluminium Flake EMI Shielding (conductive) PPO, and Alloy With Nylon, Unreinforced PPO.
