PEEK has corrosion resistance, corrosion resistance usually refers to the ability of the metal to resist the corrosive and destructive effects of surrounding media.
It is chemically resistant to chemicals, acids, concentrated sulfuric acid, alkalis, organic solvents and other chemicals, and various atmospheres. Polyetheretherketone peek has a stable chemical resistance. Chemical resistance (corrosion resistance) Its own sliding properties greatly reduce the coefficient of friction or known as a low coefficient, allowing certain parts to operate without lubricants and also in media such as water, weak acids, and alkalis. Polyetheretherketone peek has excellent sliding characteristics, especially in the bearing field. PEEK polymers or polyetheretherketone peek and their composites all have excellent wear resistance, with some PEEK having extremely low coefficients of friction and wear. As the mechanical strength is continuous in all processing conditions. PEEK has the best fatigue resistance of any resin, and the combination of excellent mechanical strength properties and fatigue resistance is the most outstanding of all plastics, with performance not inferior to that of some alloys with hence the mechanical properties.
This is one of the reasons why PEEK materials can be used where heat resistance is a concern. It can withstand short-term working temperatures of up to 300☌ and continuously use high temperatures of 250☌. PEEK with high performance engineering thermoplastic is a high temperature resistant advanced thermoplastic material.Īs with high performance along with thermal conductivity even at very high temperatures PEEK can maintain high strength with operating temperature and can reach a high glass transition temperature of 143 degrees Celsius and melting point (334☌). Peek Polymers has chemical resistance properties along with physical properties, tensile strength, dimensional stability, hence the mechanical properties offer high temperature performance.
