PEEK (Polyether ketone) stands as a pinnacle of high-performance engineering plastics, renowned for its unparalleled resistance to high temperatures, robust mechanical strength, superior chemical stability, and exceptional wear resistance. This extraordinary material finds its indispensable applications across a vast array of industries, including aerospace, medical, automotive, electronics, and industrial equipment sectors.
It boasts the following outstanding characteristics:
High temperature resilience: PEEK can maintain its structural integrity at a sustained temperature of up to 250°C, withstanding short-term peaks of 300°C, surpassing the capabilities of most other engineering plastics.
Remarkable mechanical strength: Exhibiting high rigidity and strength akin to aluminum alloy, PEEK provides excellent creep resistance, ensuring longevity and durability.
Exceptional wear resistance: Featuring a low friction coefficient ranging from 0.3 to 0.4, it is tailor-made for high wear environments, offering smooth and frictionless operation.
Superior chemical stability: Resilient against acids, alkalis, and organic solvents, except for concentrated sulfuric acid and nitric acid, enhancing its versatility.
Impeccable electrical insulation: Maintains consistent insulation performance even at high frequencies, making it ideal for electronics and electrical engineering applications.
Radiation resistance: Capable of withstanding X-rays and gamma rays, PEEK is a perfect fit for nuclear industries and medical equipment.
Medical-grade biocompatibility: Conforms to ISO 10993 standards, rendering it suitable for use in human implants, ensuring safety and reliability.
Flame retardant: PEEK is self-extinguishing with a UL94 V-0 grade, emitting low smoke and non-toxic emissions, ideal for safety applications.
Dimensional stability: Demonstrates low dimensional changes and moisture absorption, maintaining stability even in humid or high-temperature conditions.
UHMWPE (Ultra-High Molecular Weight Polyethylene) is a linear polyethylene with an impressive molecular weight, typically between 2 to 6 million, far surpassing ordinary HDPE. Known for its extraordinary wear resistance, impact resistance, and self-lubricating properties, it is extensively utilized in industrial, medical, and sports equipment sectors.
UHMWPE shines with the following exceptional performance attributes:
Unmatched wear resistance: It is the apex of wear-resistant materials, outperforming carbon steel by 7 times and nylon by 4 times.
Exceptional impact resistance: With superior toughness, it maintains its excellent impact resistance even at extremely low temperatures of -200°C.
Low friction self-lubrication: With a friction coefficient as low as 0.1 to 0.2, akin to PTFE, it is ideal for oil-free lubrication environments.
Robust chemical resistance: Resists acids, alkalis, and organic solvents, with the exception of strong oxidizing acids, enhancing durability.
Lightweight density: With a low density of 0.93-0.94 g/cm³, it is lighter than water, making it suitable for applications requiring reduced weight.
Broad temperature resilience: Usable within the expansive range of -200°C to +80°C, with some modified grades reaching up to 100°C.
Superior dielectric properties: Offers excellent electrical insulation, making it perfect for electrical applications.
Medical-grade biocompatibility: Meeting ISO 10993 standards, it is apt for human implants, ensuring medical safety and efficacy.
Enhanced UV resistance: Requires stabilizers to boost outdoor weather resistance, extending its life in open environments.
