Polyphenylene Oxide
Polyphenylene oxide properties
Polyphenylene Oxide (PPO) preserves its excellent load-bearing characteristics and dimensional stability at high temperatures. The material is also self-extinguishing and non-dripping, with excellent dielectric properties.
Polyphenylene oxide1 (PPO), also known as polyphenyl ether (PPE), is a high performance amorphous engineering thermoplastic. PPO has a high tensile and impact strength and is resistant to a wide range of chemicals, including steam and hot water, as well as mineral and organic acids. However, it is susceptible to stress cracking.
Polyphenylene Oxide colouring
Since the material’s natural colour is beige, it can be dyed in a variety of colours, but black is the most common. It is not recommended for self-colouring since the use of masterbatch will result in a significant loss of properties. UV protection is required for outdoor use.
Key benefits:
- Wide range of properties
- Low moisture absorption
- Chemical resistance
Types of Polyphenylene Oxide finishing
PPO is easy to machine, but it should be done at a slow pace. Hot stamping, hot foiling, painting, printing, and silk screening are all methods that can be used to decorate mouldings. Ultrasonic welding or adhesives may be used to connect parts.
Common applications for Polyphenylene Oxide
PPO is commonly used in the manufacture of washing machines, dishwashers, and pump components due to its strong detergent resistance and ability to be moulded to near tolerances. It is most commonly used in electrical and automotive applications due to its combination of strong heat resistance, impact efficiency, and flame retardancy.
