PEEK (Polyether ketone) is an exceptional high-performance engineering plastic known for its outstanding capability to withstand high temperatures, coupled with formidable mechanical strength. Its remarkable chemical stability and wear resistance make it a preferred choice across multiple sectors, including aerospace, medical, automotive, electronics, and industrial equipment. This versatile material is engineered to cater to the demands of cutting-edge technology.
It boasts the following remarkable characteristics:
High Temperature Resistance: Capable of enduring prolonged exposure to temperatures of up to 250°C, withstanding short-term spikes up to 300°C. This resistance surpasses most typical engineering plastics, making it ideal for challenging environments.
Impressive Mechanical Strength: Renowned for its high rigidity and strength, PEEK offers performance akin to aluminum alloys. Its excellent creep resistance ensures reliability under stress, making it indispensable in critical applications.
Wear Resistance: Featuring a low friction coefficient of 0.3~0.4, this material is designed for optimal performance in high-wear settings, ensuring durability and longevity.
Chemical Stability: PEEK's resistance to acids and alkalis, alongside organic solvents (excluding concentrated sulfuric and nitric acids), ensures its integrity and performance across various chemical exposures.
Electrical Insulation: It maintains stable insulation properties even at high frequencies, making it a superior choice for electronics and electrical engineering fields.
Radiation Resistance: Capable of withstanding X-rays and gamma rays, PEEK is essential for the nuclear industry and medical equipment where radiation exposure is a factor.
Biocompatibility: Conforming to medical grade standards (ISO 10993), PEEK is suitable for human implants, offering peace of mind in medical applications.
Flame Retardant: With a self-extinguishing nature (UL94 V-0 grade), it emits low smoke and is non-toxic, prioritizing safety and compliance.
Dimensional Stability: Exhibiting low moisture absorption, PEEK maintains its stability in humid or elevated temperature environments, ensuring consistent performance.
UHMWPE (Ultra-High Molecular Weight Polyethylene) is a linear polyethylene distinguished by a molecular weight significantly higher than standard HDPE. With its exceptional wear resistance, impact resilience, and self-lubricating capabilities, it stands as a material of choice in industrial, medical, and sports equipment sectors.
It delivers the following superior performance attributes:
Unmatched Wear Resistance: As the most wear-resistant material among plastics, UHMWPE is seven times more durable than carbon steel and four times tougher than nylon, offering unparalleled longevity.
Exceptional Impact Resistance: Retains impressive toughness even in extreme cold up to -200°C, ensuring reliability in critical conditions.
Minimal Friction: With a low self-lubricating friction coefficient of 0.1~0.2, similar to PTFE, it excels in oil-free lubrication environments.
Chemical Stability: Resistant to acids, alkalis, and organic solvents (excluding strong oxidizing acids), ensuring robustness across diverse chemical interactions.
Lightweight Advantage: With a low density of 0.93-0.94 g/cm³, it's lighter than water, suitable for applications where weight is a critical factor.
Low Temperature Tolerance: Operates effectively between -200°C to +80°C, with some modified versions pushing limits to 100°C.
Electrical Insulation: Boasts excellent dielectric properties, making it ideal for electrical insulation necessities.
Biocompatibility: Conforms to medical grade standards (ISO 10993) for safe human implant applications, ensuring biocompatibility.
UV Resistance: By incorporating stabilizers, UHMWPE enhances its resilience to outdoor weather conditions, extending its service life.
