PEEK is a unique engineering material with a melting temperature of 343 deg C and a glass transition temperature of 143 deg C.
Peek also has excellent friction and wear properties and resistance to a wide range of chemical environments, even at elevated temperatures.
Although concentrated sulphuric acid dissolves PEEK.
