Where Is PEEK Generally Used?

Understanding polyetheretherketone (PEEK)

PEEK is a high-performance engineering polymer and is one of the strongest polymers among all thermoplastics in terms of strength-to-weight ratio, and has excellent heat resistance. PEEK can be used as a substitute for other materials, including glass, steel, aluminum, and other polymers. The strength of the material is complemented by its high purity and lubricity, making it suitable for challenging applications.

Many metal components are being replaced by PEEK, allowing for maximum design innovation and flexibility in applications while minimizing the weight and cost of the system. In analytical applications, the purity, high burst pressure, and chemical resistance ensure that PEEK tubing can withstand the pressures required for critical laboratory work without contaminating the results. In biomedical environments, PEEK can be exposed to sterilization procedures such as high-pressure sterilization and gamma radiation.

Uses of Polyether ether ketone (PEEK)

PEEK for fiber optics: Branching tubes, also known as sheaths, are commonly used in fiber optics to protect these fragile communication devices. PEEK can effortlessly slide over fiber optics without affecting the fragile fibers, while reducing friction and strain. This is accomplished without using any fillers or additives in the PEEK material. The excellent strength of the PEEK material makes it suitable for protecting fiber optics. PEEK can be made into different shapes and multi-lumens to allow multiple channels. Through these multiple channels, fibers can be inserted into the outer diameter tube. The outer surface of this tubing can also be designed to form channels along the outer diameter, inner diameter, or both.

PEEK for general industry: The durability of Polyether ether ketone (PEEK) makes it a perfect substitute for many different types of materials, including other plastics that require improved design capabilities. Extruded PEEK tubing can be used for many industrial applications that require more customization. PEEK has excellent dielectric properties, which means it can provide insulation, mechanical, and physical protection wherever this material is used. PEEK products are rapidly replacing other plastics used for motor insulation, especially in Steam Assisted Gravity Drainage (SAGD) applications.

PEEK for metal substitutes: Due to PEEK's excellent strength-to-weight ratio, engineers can consider using PEEK to replace heavier metal parts. PEEK can withstand mechanical and physical stresses, and also has excellent chemical resistance and high heat resistance, which collectively provide advantages over metal parts. These qualities make Polyether ether ketone (PEEK) suitable for automotive, aerospace, and other general industrial environments.
