China’s commerce ministry said on Thursday it will impose anti-dumping tariffs on polyphenylene ether imported from the United States.

 

The measures will be effective from Jan. 7, the ministry said in a statement.

 

Polyphenylene Ether (PPE), sometimes called PPO, is a polymer that offers excellent heat resistance, dimensional stability and mechanical properties. PPE also has low moisture absorption and excellent hydrolysis resistance and can be made flame retardant. Common applications for PPE include components in printers and copiers, electrical devices like connectors and circuit breakers and in vending machines and water softeners. PPE is normally blended with PS or nylon to improve its processability.

 

While originally PPEs were developed for use in extreme environments that were experienced in aerospace applications, they are now used in other applications requiring low volatility and excellent thermo-oxidative and ionizing radiation stability. Such applications include use as diffusion pump fluids; high vacuum fluids; and in formulating jet engine lubricants, high-temperature hydraulic lubricants and greases, and heat transfer fluids. In addition, because of excellent optical properties these fluids have found use in optical devices.
