Using PEEK for making machine or instrument components helps these parts retain their chemical structure and properties in wet areas. Low Absorption of Water and Resistance to Radiation Therefore, it can maintain high wear resistance with various physical pressure conditions, surface roughness, temperature, and speed relative to the contact surface. This property makes it a suitable material to withstand great pressure during machining.įurthermore, PEEK provides excellent wear resistance with a low coefficient of friction.

Also, it has excellent creep resistance properties (the ability of a substance to deform slowly over a long period of exposure to stress). PEEK has the highest fatigue and stress-retaining properties of all other plastics.

It has a low linear expansion coefficient and good dimensional stability. PEEK and other high-temperature thermoplastics have high impact strength and retain their size at elevated temperatures. Excellent Mechanical Properties, Creep Resistance, Wear, and Friction Resistance. In addition, this thermoplastic is a self-extinguishing material during combustion it produces little or no toxic gas and smoke. The high-temperature workability and high thermal decomposition properties of PEEK ensure this compatibility. These methods include injection moulding, extrusion moulding, melt spinning, etc. Although it’s a super high-temperature thermoplastic material, it can be processed with different material processing methods. PEEK material assures high workability during plastic CNC machining due to its good processing performance. High Workability Rate and Consistent Performance Even at High Temperatures Therefore, it works perfectly well during peak machining at elevated temperatures and does not deform at higher temperatures. This property makes it suitable for high-performance wire use to ensure good insulation.įurthermore, PEEK material is highly durable and has a high melting point. In addition, it has high resistance to gamma radiations, more significant than that of polystyrene (material with the most resistance to radiations in general-purpose resin use). Since it has a stable chemical structure when chemically attacked, the material can operate perfectly under high doses of ionization radiation. During normal conditions, only concentrated sulphuric acid can dissolve this plastic.Īlso, PEEK has high electrical performance over high temperatures and frequencies. It provides resistance similar to nickel steel and can retain its non-corrosive and chemical structure with most metals, even at high temperatures. PEEK material gives high resistance against corrosive chemicals. Excellent Chemical, Electrical, and Temperature Resistance Manufacturers widely appreciate the following properties of this thermoplastic: 1. This is due to the excellent and exceptional properties of Peek plastic. Industries producing diverse objects, such as medical implants, use PEEK widely in their productions. Your application will determine the grade of PEEK you choose to machine. Other medical-grade PEEK variations are useful for custom components and applications like spinal devices and articulating joints. Thus, they can be in contact with tissues and blood. This PEEK grade includes polymers used for medical implants to mimic the stiffness of bones. It also has a low coefficient of friction, with its biggest attribute being its ability to retain its mechanical and physical properties even in extreme conditions. Industrial-Grade PEEK: This is a strong, abrasion-resistant plastic with increased impact strength. The two major classifications of PEEK are: It is available in granular form, bar forms for CNC machining, and filaments. The semi-crystalline thermoplastic polymer occurs in different forms. Therefore, it can be used in hot water or steam and progressively to a temperature high temperature up to 250 oC. They melt at about 343 oC and operate perfectly at higher temperatures. PEEK plastics have the exceptional advantage of retaining their properties even at high temperatures. This semi-crystalline material is used in diverse industrial parts and components due to its excellent mechanical properties, wear resistance, high chemical resistance, water resistance, and abrasion resistance. It is a semi-crystalline high-performance engineering thermoplastic. PEEK is a thermoplastic polymer of Polyether ether ketone.
