Guangzhou IDEAL is a Chinese manufacturer and supplier specializing in PEEK polyetheretherketone products. Our PEEK series includes PEEK rods, sheets, tubes, profile blanks, and custom PEEK parts. Custom sizes and filled PEEK grades are available on request. PEEK (polyetheretherketone) is an aromatic thermoplastic polymer composed of repeating units of polyaryletherketone (PEK), each containing two ether groups and one ketone group. It is a semi-crystalline, high-performance engineering thermoplastic with a well-defined melting point of 334°C, a narrow softening temperature range, and a glass transition temperature (Tg) of 143°C. Its maximum crystallinity is approximately 48%, typically ranging from 20% to 30%. Its density in the amorphous state is 1.265 g/cm³, while its density at maximum crystallinity is 1.32 g/cm³. PEEK is renowned for its exceptional mechanical properties, chemical resistance, thermal stability, and excellent electrical properties. It offers a long-term operating temperature range of 250°C to 260°C and can be temporarily extended to 300°C.
PEEK has a glass transition temperature of 143°C and a melting point of 334°C. When filled with glass or carbon fiber, its heat deflection temperature reaches over 326°C. The UL-approved long-term operating temperature is 260°C.
PEEK boasts exceptional strength and hardness, maintaining structural integrity even under repeated high loads, stresses, and impacts.
PEEK maintains high stability and corrosion resistance under the influence of many strong acids, bases, and other chemicals. This is due to its unique molecular structure, which contains aromatic rings, aliphatic alkane chains, and ketone groups formed at 240°C. These groups form a dense protective oxide film on the material's surface, preventing corrosion from external chemicals and enhancing its corrosion resistance.
PEEK's fatigue resistance stems from its excellent molecular structure and crystallization properties. Under long-term alternating stress, PEEK maintains excellent stability and reliability, making it less susceptible to fatigue failure.
PEEK has excellent radiation resistance, maintaining its structure and properties when exposed to radiation such as gamma rays and X-rays.
PEEK's self-lubricity is due to the presence of benzene rings and oxygen atoms in its molecular structure. This chemical structure enables PEEK to automatically form a lubricating film, reducing the coefficient of friction and improving wear resistance.
PEEK's excellent wear resistance is due to its high molecular weight, high hardness, and low coefficient of friction.
PEEK's excellent dimensional stability is due to its extremely low water absorption and linear thermal expansion coefficient.
PEEK exhibits excellent electrical insulation properties over a wide temperature and humidity range. Its high volume and surface resistivity are making it increasingly important in the electronic information field.
PEEK's excellent high-temperature resistance, outstanding mechanical properties, and dimensional stability make it widely used in advanced manufacturing.
PEEK parts' excellent electrical properties make them suitable for electronic component packaging, high-voltage switches, motors, and other equipment in the electronics and electrical industry.
PEEK's high-temperature resistance, hydrolysis resistance, and radiation resistance have enabled cables, wires, coil bobbins, connectors, and valves made from it to be successfully used in energy sectors such as nuclear power plants and oil exploration and production.
Due to its biocompatibility and sterilization resistance, PEEK is used in the medical field to manufacture artificial bones, dental implants, endoscope components, dental scalers, and surgical tools.
PEEK's excellent chemical stability and low moisture absorption rate make it safe for food contact materials. In the food industry, it can be used as components for food and beverage processing equipment.

Natural PEEK Film is a 100% virgin, unfilled and non-pigmented PEEK cast film. It is mainly mass-produced via high-temperature T-die cast extrusion, while high-end ultra-thin and high-flatness products adopt the biaxially oriented BOPEEK process. Featuring low ion precipitation, ultra-high cleanliness, excellent biocompatibility and superior insulation performance, the film supports repeated high-temperature sterilization and is widely applied in IT manufacturing, precision electronics, biomedicine and other high-end industries.
Carbon Filled PEEK Film (chopped carbon‑fiber‑filled polyetheretherketone cast film) uses semi‑crystalline high‑performance thermoplastic PEEK resin as its matrix. It is compounded with chopped PAN‑based carbon fiber and continuously formed through a T‑die flat‑die cast‑extrusion process to produce a black engineering‑plastic film material.
