What is PEEK Plastic

The core design of RTP PEEK 2287 LF is the Low Flow System. This type of peek plastic is usually used in engineering manufacturing for structural components with high precision and low deformation rate.
A low-flow system means that the melt flows more slowly in the mold cavity, crystallizes more fully, and the molecular orientation is more uniform, thereby achieving higher dimensional stability and lower internal stress accumulation in complex structural components.

The four major engineering values brought by low-flow design:

  ・Enhanced structural density: The low melt shear rate results in fewer delamination and bubble defects in the products.

  ・Homogenization of mechanical properties: Carbon fibers are distributed more evenly, avoiding local stress concentration.

  ・Controllable size deformation: The shrinkage rate is only 0.05%, which is a high-precision representative among peek plastics.

  ・Processing stability: Reduces the risk of flow marks and short shots in complex molds or thick-walled parts.

01 | Performance Analysis: The balance between high strength and high thermal stability of PEEK plastic

Compared with ordinary PEEK materials, the low flow characteristics of this peek plastic make the carbon fiber distribution more uniform, the molecular structure dense, and it can maintain stable size and mechanical properties in high-temperature and high-load environments. It is a typical structure-grade material.

02 | Processing and Process Adaptation: Mold Strategies for Low-Flow PEEK Plastic

RTP PEEK 2287 LF is produced by injection molding process and is particularly suitable for medium and thick-walled, high-precision structural components.
As a low-flow peek plastic, it has higher control requirements for mold temperature and injection speed, but the rewards it brings are high part density, small warpage and dense structure.

Recommended Process Window:

  ・Barrel temperature: 370-400℃

  ・Mold temperature: 160-200℃

  ・Drying conditions: 150℃ for 3 hours

  ・Wall thickness recommendation: 2mm or more to ensure stable flow filling and crystallization

Process advantages:

  ・Low-flow PEEK melts form a denser molecular structure;

  ・The dimensional repeatability of the formed products is high.

  ・Avoid air marks and charring caused by high-speed injection;

  ・It is particularly friendly to complex molds and deep cavity structural components.

03 | Application Fields: A New Option for PEEK Plastic in High-Load Structural Components

The low flow property of RTP PEEK 2287 LF makes it an ideal material for applications where high precision and high strength coexist

  ・Automobile structural components: engine mounts, clutch housings, fuel system valve bodies;

  ・Electronic and electrical components: high-temperature connectors, insulating frames, sensor housings;

  ・Industrial equipment: pump and valve housings, mechanical support parts, sealing rings;

  ・Aviation and energy equipment: High-temperature insulating brackets, chemical anti-corrosion isolation parts.

In these fields, the processing characteristics of low-flow peek plastic enable the molded parts to maintain high density and excellent dimensional control performance, significantly reducing the costs of mechanical processing and calibration.

04 | Industry Value: The Engineering Significance of Low-flow PEEK Plastic

The low-flow system of RTP PEEK 2287 LF brings the following significant advantages in engineering practice:

  ・Dimensional accuracy: 0.05% shrinkage rate, suitable for automatic assembly accessories;

  ・Long-term reliability: Maintains stable mechanical properties in an environment of 300℃.

  ・Surface quality: Fibers are not exposed and have good polishing properties.

  ・Alternative metals: Combining strength and rigidity, with significantly reduced weight.

This makes it not just a material, but a type of engineering-grade peek plastic solution, representing the direction of the transformation of high-temperature structural components from metal to polymer lightweight.
