PEEK O-Rings & Backup Rings

PEEK is a high-temperature thermoplastic with a high glass transition temperature (143°C) and melting point (334°C), and a loaded thermal deformation temperature of up to 316°C (30% glass fiber or carbon fiber reinforced grades).PEEK seals have good performance, stable dimensions, customizable specification size, high temperature resistance, abrasion resistance and strong mechanical properties. High temperature resistant PEEK has a high glass transition temperature and melting point (334°C), which is one of the reasons it can be reliably used in applications where heat resistance is required. It has a loaded thermal transition temperature of up to 316°C and a continuous use temperature of 260°C. PEEK in high-performance polymers with other general-purpose plastics can not be compared to the comprehensive performance, with a variety of harsh environments applicable to the performance, has been successfully and widely used in aerospace, automotive, electronic semiconductors, electromechanical and other industries in the requirements of the more demanding occasions. It is the user to carry out new product development, improve product life and reliability of materials.

PEEK Main Characteristics Advantages

1.PEEK gasket than the strength and stiffness: PEEK gasket / gasket / gasket plate density is small, specific strength (σb / ρ), specific stiffness (E / ρ) is quite high.PEEK (polyether ether ketone) plastic raw material resin has good toughness and rigidity, it has an alloy material comparable to the excellent fatigue resistance to alternating stresses

2.PEEK gasket density is small: for reducing the weight of mechanical equipment and energy saving is of great significance, especially for vehicles, ships, airplanes, spacecraft.

3. Polyether ether ketone PEEK retaining ring with good chemical stability: PEEK has good resistance to acids, alkalis, salts, water and gases, in general conditions, they do not have a chemical reaction with these substances. Resistant to a variety of media, in line with the FDA certification, non-toxic, very excellent chemical resistance

4.PEEK support ring electrical insulation, thermal insulation, acoustic insulation performance is good.PEEK (polyether ether ketone) plastic raw material resin has good electrical insulation properties, and maintained to a very high temperature range. Its dielectric loss at high frequencies is also very small.
