उत्पाद वर्णन

Polyetheretherketone (PEEK) Properties /Description

Polyetheretherketone (PEEK) is generally immediately available in most volumes. Nanochemazone produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.



Exceptional Mechanical and Thermal Properties

With tensile strength ranging from 90 to 100 MPa and a thermal conductivity of 0.25 W/mK, PEEK withstands significant mechanical stress and elevated temperatures up to its 343C melting point. Its UL94 V-0 flammability rating and resistance to weather, chemicals, and impact ensure operational safety and material longevity across industries.


Versatile Applications Across Industries

PEEKs combination of chemical inertness, outstanding dielectric properties, and stability under harsh conditions supports its use in aerospace, automotive, medical, and marine engineering. It serves as a trusted engineering plastic for parts, electrical insulation, and medical implants, available in granules, powder, rods, sheets, and tubes to meet diverse application needs.


Reliable Safety and Storage

PEEK is non-poisonous, odorless, and tasteless, offering safety in handling and use. For best results, store it in a cool, dry place, away from direct sunlight. Its physiological inertness makes it suitable for food-contact and medical applications, while standard compliance (ASTM D6262, ISO 1043) assures quality and consistency.

FAQs of Polyetheretherketone (PEEK):


Q: How is Polyetheretherketone (PEEK) commonly processed for industrial applications?

A: PEEK can be processed using standard thermoplastic methods such as injection molding, extrusion, and compression molding. Its semi-crystalline nature and high melting point of 343C require precise temperature control during manufacturing, enabling the production of intricate, high-performance components for aerospace, automotive, and medical applications.

Q: What benefits does PEEK offer compared to other engineering plastics?

A: PEEK stands out for its combination of high tensile strength, excellent impact resistance, thermal stability, and chemical inertness. Unlike many plastics, it retains mechanical properties at elevated temperatures and has a UL94 V-0 flammability rating, making it suitable for high-demand environments where safety and durability are paramount.

Q: Where can PEEK be used and what forms are available?

A: PEEK finds applications in areas such as aerospace, automotive, electronics, medical devices, marine engineering, and chemical processing. It is supplied as granules, powder, rods, sheets, and tubes, enabling manufacturers and designers to select the most suitable form for their specific needs.

Q: What are the usage and handling guidelines for PEEK products?

A: PEEK products should be stored in a cool, dry place away from direct sunlight to maintain material integrity. Handling is safe as PEEK is non-poisonous, odorless, and tasteless, but heat-resistant gloves are recommended when processing at high temperatures due to its elevated melting point.

Q: When should engineers choose PEEK for demanding applications?

A: Engineers should select PEEK when they require a material that can withstand high mechanical stress, elevated temperatures, and aggressive chemicals while maintaining performance. Its superior weather resistance, low water absorption, and dielectric properties make it ideal for specialized and high-performance components.

Q: Is PEEK suitable for medical and electrical applications?

A: Yes, PEEKs physiological inertness and biocompatibility make it approved for use in medical implants and instruments. Additionally, its excellent dielectric constant (3.2 at 1 MHz) and electrical insulation properties ensure reliable performance in electronic components.
