What is PEEK Resin

With the continuous expansion of the application of high-performance engineering plastics in the aerospace, automotive, medical and electronic and electrical industries, polyetheretherketone (PEEK), as the most representative high-end plastic, has gradually become an important choice for metal alternatives due to its outstanding high-temperature resistance, mechanical strength and chemical resistance.

The 2200 series low-flowability PEEK Resin developed by RTP Company, while maintaining the basic properties of PEEK, is reinforced/modified with glass fiber, carbon fiber, PTFE and aramid fiber, etc., endowing the material with a richer combination of properties to meet the demanding requirements of different working conditions.

01 | Product Overview

The RTP 2200 series belongs to low-flowability modified PEEK and is more suitable for injection molding with high-precision and complex molds. This series of products achieves the following performance characteristics through different reinforcing filling schemes:

  ・High strength and high modulus: The glass fiber and carbon fiber reinforced type significantly enhances structural strength and is suitable for load-bearing parts.

  ・Stable high-temperature resistance: The heat distortion temperature of some models can reach up to 316℃, meeting the requirements of harsh environments.

  ・Wear resistance and self-lubrication: PTFE-modified types exhibit a low coefficient of friction, making them suitable for sliding and rotating components.

  ・The comprehensive performance is adjustable: from toughness to rigidity, from lightweight to wear resistance, covering different application requirements.
