What are PEEK Pellets - TK4600

PEEK TK4600 is a flame-retardant PEEK pellets developed by Sumitomo Chemical, featuring an inorganic filling system and excellent thermal stability as its core characteristics. This material, while balancing high

Its particle fluidity is uniform and stable, and it can be adapted to various molding methods, including injection molding, extrusion, compression molding and CNC machining.

Thanks to the thermal stability and low shrinkage characteristics of the material, the dimensional accuracy and repeatability of the mold parts are extremely high. Even in high-temperature and high-pressure environments, the stability of the product's geometric shape can be maintained.

Meanwhile, PEEK pellets releases less gas during processing, causes less mold contamination, greatly improves production efficiency and reduces maintenance costs.

For batch manufacturing enterprises, this means a lower defect rate and higher consistency of good products.

05 | Innovation and Industry Competitive Advantage

The birth of PEEK TK4600 not only optimizes the material's performance but also demonstrates Sumitomo Chemical's leading strength in polymer structure design and flame retardant system innovation:

  ・Inorganic filling technology - while maintaining light weight, it significantly enhances structural rigidity and wear resistance;

  ・Intrinsic flame retardant system - can reach UL94 V-0 standard without the addition of halogen, in line with international environmental protection trends;

  ・Low water absorption and high insulation performance - ensuring electrical safety and long-term dimensional stability;

  ・Outstanding thermal cycling durability - no significant performance degradation after multiple heating and cooling cycles, ensuring a service life far exceeding that of conventional plastics.

These innovations have made the TK4600 a rare category in the high-end market, especially favored by the manufacturing industries in Europe, America, Japan and South Korea.

06 | Customer Feedback: The trusted choice of global manufacturers

Several international customers have reported that PEEK TK4600 has demonstrated in practical applications:

  ・Higher mold replication accuracy, reducing later debugging;

  ・Excellent mechanical strength retention rate at high temperatures;

  ・The friction and wear are extremely low under long-term operation.

  ・It can work stably for a long time in electrical components without carbonization or deformation.

  ・When combined with metal or other engineering plastic parts for processing, the dimensional matching degree is high.

This means that PEEK TK4600 is not merely a material, but also an "added bonus" for production reliability and brand reputation.

07 | Frequently Asked Questions (FAQ)

Q1: What are the differences between PEEK TK4600 and ordinary PEEK?
