Cnc Machining PEEK

Polyetheretherketone (PEEK) is a high polymer composed of repeating units containing one ketone bond and two ether bonds in the main chain structure, and is a special polymer material. It has physical and chemical properties such as high temperature resistance and chemical resistance. It is a kind of semi-crystalline polymer material. It can be used as high temperature resistant structural material and electrical insulating material. It can be compounded with glass fiber or carbon fiber to prepare reinforcing material. Generally, a type of polyarylene ether polymer obtained by condensation with aromatic dihydric phenol is used.

PEEK plastic material has numerous applications in aerospace, medical devices (as artificial bone to repair bone defects) and in industry.

This is the standard grade of PEEK™ without any fillers or reinforcements. It exhibits high mechanical strength, excellent chemical resistance, and good electrical properties.

Glass-Filled PEEK™

This grade of PEEK™ is reinforced with glass fibers, which enhances its strength, stiffness, and dimensional stability. Glass-filled PEEK™ has improved wear resistance and lower thermal expansion compared to unfilled PEEK™.

Carbon-Filled PEEK™

Carbon fibers are added to PEEK™ to create a grade with enhanced mechanical properties, such as higher tensile strength and stiffness. Carbon-filled PEEK™ is also more electrically conductive than the unfilled version.

Bearing Grade PEEK™

This grade contains added polymeric and solid lubricants to reduce friction and improve wear resistance. Bearing grade PEEK™ is well-suited for applications requiring excellent tribological properties.

What Is PEEK Plastic & The Features Of PEEK

What Is PEEK Plastic
It all starts with you. Our goal is to make your ideas come to life one layer at a time

PEEK (polyetheretherketone) plastic raw material is an aromatic crystalline thermoplastic polymer material with high mechanical strength, high temperature resistance, impact resistance, flame retardant, acid and alkali resistance, hydrolysis resistance, wear resistance, fatigue resistance, radiation resistance and good electrical properties.

  • High temperature resistance: It has high glass transition temperature (Tg=143°C) and melting point (Tm=343°C), its thermal deformation temperature under load is as high as 316°C, and its instantaneous use temperature can reach 300°C.
  • Mechanical properties: It has rigidity and flexibility, especially the fatigue resistance under alternating stress is very outstanding, which is comparable to alloy materials.
  • Self-lubrication: It has excellent sliding properties and is suitable for occasions where low friction coefficient and wear resistance are strictly required, especially PEEK modified with carbon fiber and graphite in a certain proportion has better self-lubricating properties.
  • Corrosion resistance: Except for concentrated sulfuric acid, PEEK is insoluble in any solvent and strong acid and alkali, and it is resistant to hydrolysis and has high chemical stability.
  • Flame retardancy: It is self-extinguishing, even without any flame retardant, it can reach the 94V-0 level of the UL standard.
  • Ease of machining: It has the characteristics of good high temperature fluidity and high thermal decomposition temperature. Various machining methods can be used: injection molding, extrusion molding, compression molding and melt spinning.
  • Peeling resistance: The peeling resistance is very good, so it can be made into a thinly coated wire or magnet wire, and can be used in harsh conditions.
  • Fatigue Resistance: The best fatigue resistance among all resins.
  • Radiation resistance: The ability to withstand high radiation is very strong, surpassing that of polystyrene, which has the best radiation resistance among general-purpose resins. It can be made into a high-performance product that can maintain a good insulating ability when the γ-irradiation dose reaches 1100Mrad.
  • Hydrolysis resistance: PEEK and its composite materials are not chemically affected by water and high-pressure water vapor, and products made of this material can maintain excellent properties when used continuously in high-temperature and high-pressure water.
  • Smoke: PEEK has the lowest smoke among plastics.
  • Toxic gas escape: PEEK is the same as many organic materials. When decomposed at high temperature, PEEK mainly produces carbon dioxide and carbon monoxide. Using the British aircraft test standard BSS 7239, a very low concentration of toxic gas can be detected. This detection process needs to be in 1. Completely burn 100 grams of sample in a cubic meter of space, and then analyze the poisonous gas produced in it. The toxicity index is defined as the ratio of the concentration of poisonous gas produced under normal conditions to the lethal dose in 30 minutes. The index of PEEK450G is 0.22. And no acid gas was detected.
  • Insulation stability: has good electrical insulation properties and maintains it to a very high temperature range. Its dielectric loss is also small at high frequencies.
  • Stability: Has excellent dimensional stability properties, which is important for some applications.

Changes in environmental conditions such as temperature and humidity have little effect on the size of PEEK parts, which can meet the requirements for use under high dimensional accuracy requirements.

  1. The injection molding shrinkage of PEEK plastic raw materials is small, which is very beneficial to control the dimensional tolerance range of PEEK injection parts, so that the dimensional accuracy of PEEK parts is much higher than that of general-purpose plastics;
  2. The thermal expansion coefficient is small, and with the change of temperature (caused by the change of ambient temperature or frictional heat generation during operation), the size of PEEK parts changes very little;
  3. Good dimensional stability. The dimensional stability of plastics refers to the dimensional stability of engineering plastic products during use or storage. This dimensional change is mainly due to the increase in the activation energy of polymer molecules. caused by some degree of curling;
  4. PEEK has outstanding heat-resistant hydrolysis properties, low water absorption under high temperature and high humidity environment, and there is no obvious change in size of general-purpose plastics such as nylon due to water absorption.
