Polyetheretherketone (PEEK) is a high-performance engineering polymer that has one of the highest strength-to-weight ratios of all thermoplastics and superior heat resistance. Polyetheretherketone can be used as a substitute for other materials, including glass, steel, aluminum, and other polymers. Its strength is complemented by its high purity and lubricity, making it suitable for challenging applications.
PEEK is applied to weaving: Single-strand PEEK fibers have outstanding corrosion resistance, wear resistance, toughness, and tensile strength. It is an ideal braiding material for cable and wire sheaths and performs well at temperatures up to 500°F (260℃). This monofilament is also used as a substitute for metal in conduit braiding reinforcement.
PEEK is used in critical fluid transport: PEEK's mechanical integrity, chemical resistance, and high maximum temperature make it an excellent choice for key fluid transfers that focus on heat. The material can withstand a variety of solvents, acids, and bases. PEEK's ability to withstand high burst pressure due to its high purity makes it the preferred material for biomedical, analytical, and pharmaceutical applications to ensure analysis liquids are not contaminated. In HPLC applications, PEEK has become the gold standard and materials can be purchased with nominal wall thicknesses as thin as 0.0015 inches (0.0381 millimeters) and inner diameters as low as 0.002 inches (0.051 millimeters).
Polyetheretherketone applications in fiber optics: Split tubing, also known as protective tubing, is often used in fiber optics to protect these fragile communication devices. PEEK can slide effortlessly over the fiber without affecting the fragile fiber, while reducing friction and stress. The material does this without the use of any fillers or additives. PEEK's excellent strength makes it suitable for protecting fiber optics. The thermally stable PEEK coating has all the beneficial qualities of PEEK and has very low attenuation over fiber lengths and temperatures exceeding 250℃. PEEK can be shaped and multi-chambered to allow for multiple channels. Through these multiple channels, fibers can be inserted into the outer diameter tube. The outer surfaces of this type of tube can also be designed to produce channels along the outer diameter, inner diameter, or both.
PEEK is applied to general industry: PEEK's durability makes it a perfect substitute for many different types of materials, including plastics that need improved design capabilities. After extrusion, PEEK tubing can be used for many industrial applications that require more customization.
Polyetheretherketone applications in insulation: PEEK has excellent dielectric properties, meaning it can provide insulation, mechanical, and physical protection wherever it is used. PEEK products are rapidly replacing other plastics used for motor insulation, especially in steam-assisted gravity drainage (SAGD) applications.
