High-strength insulation materials are here! Glass-fiber-modified PEEK is ideally suited for high-temperature, high-pressure, and high-strength applications such as cable casings, connectors, and switches, and is widely used in semiconductor manufacturing and electrical and electronic applications.
1. Super strong mechanical strength and rigidity: stronger and harder than pure PEEK
2. Maintain dimensional stability and low creep under high temperature and high pressure environments.
3. Low thermal expansion coefficient: reduces the impact of temperature changes and has lower thermal conductivity.
High temperature resistance: It has a high glass transition temperature (Tg=143℃) and melting point (Tm=343℃), its load heat deformation temperature is as high as 316℃, and its instantaneous operating temperature can reach 320℃.
Mechanical properties: It has both rigidity and flexibility, especially its fatigue resistance under alternating stress is very outstanding, comparable to that of alloy materials.
Self-lubricating property: It has excellent sliding properties and is suitable for applications that strictly require low friction coefficient and wear resistance. In particular, PEEK modified by mixing carbon fiber and graphite in a certain proportion has better self-lubricating properties.
Corrosion resistance: Except concentrated sulfuric acid, PEEK is insoluble in any solvents, strong acids, and strong alkalis at room temperature. It is also resistant to hydrolysis, has very low water absorption, and has high chemical stability.
Flame retardancy: It is self-extinguishing and can reach UL standard 94V-0 level even without adding any flame retardant.
Ease of processing: Various processing methods can be used: injection molding, extrusion molding, compression molding and melt spinning, etc.
Peel resistance: It has good peel resistance, so it can be made into thinly coated wires or magnet wires and can be used under harsh conditions.
Fatigue resistance: It has the best fatigue resistance among all resins.
Radiation resistance: It has a strong ability to withstand high radiation, exceeding the best radiation resistance of general-purpose resins, polystyrene. It can be made into a high-performance material that can still maintain good insulation performance even when the gamma irradiation dose reaches 1100 Mrad.
Hydrolysis resistance: PEEK and its composite materials are not chemically affected by water and high-pressure steam. Products made of this material can still maintain excellent properties after continuous use in high-temperature and high-pressure water.
Safety and environmental protection: PEEK has low smoke emission and toxic gas emission: Like many organic materials, PEEK mainly produces carbon dioxide and water when decomposed at high temperature.
Electrical properties: It has good electrical insulation properties and maintains them over a high temperature range. Its dielectric loss is also very small at high frequencies.
Dimensional stability: PEEK has a small thermal expansion coefficient, and changes in environmental conditions such as temperature and humidity have little effect on the size of PEEK parts, which can meet the use requirements under working conditions with relatively high dimensional accuracy requirements.
