PEEK (Polyether ketone) is a top-tier, high-performance engineering plastic renowned for its extraordinary resilience to high temperatures, exceptional mechanical strength, unwavering chemical stability, and superior wear resistance. Its versatility makes it indispensable across a multitude of domains, including aerospace, medical, automotive, electronics, and industrial equipment sectors.
Noteworthy Characteristics:
High Temperature Resilience: Capable of enduring long-term use at temperatures reaching an impressive 250 °C, withstanding short-term exposure up to 300 °C, surpassing most engineering plastics.
Robust Mechanical Strength: Exhibits high rigidity and strength comparable to aluminum alloys, coupled with remarkable creep resistance, ensuring durability in demanding applications.
Wear Resistance: Features a low friction coefficient (0.3~0.4), making it ideal for environments subjected to intense wear.
Chemical Stability: Demonstrates acid and alkali resistance, along with resilience to organic solvents, with the exception of concentrated sulfuric and nitric acids.
Electrical Insulation: Maintains stable insulation performance even at high frequencies, making it a perfect fit for electronics and electrical engineering fields.
Radiation Resistance: Capable of withstanding X-rays and gamma rays, making it suitable for applications in the nuclear industry and medical equipment.
Biocompatibility: Meets stringent medical-grade standards (ISO 10993), allowing for safe use in human implants.
Flame Retardant: Self-extinguishing qualities (UL94 V-0 grade) ensure low smoke emission and non-toxicity.
Dimensional Stability: Exhibits low moisture absorption, maintaining form and function even in humid or high-temperature conditions.
UHMWPE (Ultra-High Molecular Weight Polyethylene) is an exceptional linear polyethylene with a molecular weight ranging between 2 million and 6 million, far surpassing ordinary HDPE. Its unparalleled wear resistance, impact resistance, and self-lubricating properties make it a sought-after material in industrial, medical, and sports equipment applications.
Remarkable Performance Attributes:
Supreme Wear Resistance: The pinnacle of wear-resistant materials, boasting wear resistance seven times that of carbon steel and four times that of nylon.
Outstanding Impact Resistance: Exhibits exceptional toughness, retaining superior impact resistance even at frigid temperatures as low as -200 °C.
Self-Lubricating: Possesses a low friction coefficient (0.1~0.2, closely akin to PTFE), making it suitable for environments requiring oil-free lubrication.
Chemical Stability: Resistant to acids, alkalis, and organic solvents, barring strong oxidizing acids.
Lightweight: Featuring a low density of 0.93-0.94 g/cm³, it is lighter than water, suitable for applications demanding reduced weight.
Temperature Range: Functional within a broad temperature spectrum of -200 °C to +80 °C, with certain modified variants extending up to 100 °C.
Dielectric Properties: Exhibits excellent electrical insulation, ideal for applications requiring dielectric solution.
Biocompatibility: Compliant with medical-grade standards (ISO 10993), suitable for use in human implants.
UV Resistance: Requires stabilizers for enhanced weather resistance in outdoor applications.
