PEEK insulated wire is a semi-crystalline, thermoplastic aromatic polymer that possesses a range of remarkable properties. Polyetheretherketone (PEEK) is a new type of thermoplastic material synthesized from 4,4'-difluorobenzophenone and hydroquinone using diphenyl sulfone as a solvent and catalyzed by alkali metal carbonates (sodium carbonate or potassium carbonate) through a polycondensation reaction.
As a representative of the Polyaryletherketone (PAEK) family, it stands at the pinnacle of the polymer performance pyramid and is known as the "King of Resin." It boasts excellent mechanical properties, stable physical and chemical properties, lightweight characteristics, and exceptional biocompatibility, making it an ideal new high-performance polymer to replace metal materials.
Firstly, PEEK insulated wire has extremely high heat resistance, with a glass transition temperature reaching 143℃ and a melting point around 334℃. It can be used long-term at 250℃ and short-term even up to 300℃.
PEEK insulated wire exhibits high strength and high modulus characteristics. Its tensile strength can reach over 100MPa, and its flexural strength and modulus are also quite impressive. Additionally, it has good toughness and impact resistance. These combined properties allow PEEK insulated wire to withstand complex stresses without easily breaking, meeting the requirements of various stringent conditions.
PEEK insulated wire has excellent chemical resistance to most chemical reagents, including organic solvents, acids, and bases. Whether in highly corrosive chemical environments or complex industrial media, PEEK insulated wire can maintain its performance without being affected.
The low friction coefficient and wear resistance of PEEK insulated wire make it effective in reducing wear when manufacturing bearings, gears, and other moving parts, thus extending their lifespan. Its flame retardancy gives it a unique advantage in fields with high fire safety requirements such as electronics and electrical appliances, and its electrical insulation properties meet the stringent requirements of electronic components for insulating materials.
PEEK (Polyetheretherketone) is a high-performance specialty engineering plastic, and its domestication journey reflects China's self-innovation capability in material science.
Zypeek, one of the earliest domestic companies engaged in the production of PEEK insulated wire, has achieved remarkable success. Its annual production ranks leading domestically, and it continues to innovate and develop in high-end products such as implant-grade PEEK, wires, and wafer cases, achieving some sales revenue.
Replacing Metal Materials
PEEK insulated wire has good rigidity and strength while being lighter than most metals. Thus, it is widely used to replace traditional metal materials. As the demand for lightweight and energy efficiency increases, the application of PEEK in the automotive, aerospace, and other industries is expanding.
