Why Choose VESTAKEEP® 2000G

Among engineering plastics, PEEK is renowned for its heat resistance and chemical stability, but the processability varies significantly among different grades.

VESTAKEEP® 2000G precisely controls the molecular weight distribution, enabling the material to maintain mechanical toughness and flame retardancy while also having ideal flow performance and demolding performance.

For manufacturers who pursue dimensional accuracy, cleanliness and flame retardant safety, it is a highly balanced material choice.

01 | Core Characteristics of Materials

Hệ thống không được gia cố: Maintains the cleanliness of pure resin, with no glass fiber precipitation or mold wear issues;

Medium viscosity formula: Balancing fluidity and mechanical strength, suitable for injection molding of medium and thin-walled parts;

Flame retardant safety: UL94 V-0 is achieved at a thickness of 0.8-1.6mm.

Clean and free of precipitates: Meets the requirements of semiconductor and medical contact components;

Stable shrinkage control: Approximately 0.7% flow direction, with high dimensional repeatability accuracy.

02 | Processing Technology Performance

Wide Processing Temperature Window: Melting temperature is approximately 340°C, and the resin remains stable at 370°C.

Smooth demolding: The non-reinforced system avoids the problem of mold adhesion caused by fiber breakage.

Flow balance: Suitable for multi-cavity molds and fine flow channel designs;

Mold temperature control suggestion: A mold temperature range of 170-200°C can achieve a denser crystalline structure.

Reprocessing friendly: The proportion of recycled material mixing can be controlled within 20% without significantly affecting performance.

03 | Applicable Fields and Formed Value

Semiconductor components: Heat-resistant and non-precipitating, suitable for high-cleanliness parts such as vacuum chambers and wafer fixtures;

Medical device structural components: Compatible with multiple sterilization methods (EO, steam, gamma rays);

Precision motion mechanism: Friction-stable, low-noise operation, suitable for gears, sliders, and bearings;

General mechanical parts: Maintain dimensions and strength for a long time in harsh environments.

05 | Forming Precautions and Process Optimization Suggestions

Drying management: It is recommended to dry the material at 150°C for 3 hours before processing to avoid air bubbles and silver streaks.

Injection molding parameters: The screw speed should be moderate, and the back pressure should not be too high to prevent degradation.

Mold material selection: It is recommended to use polished surfaces or chrome-plated mold cavities to prevent resin adhesion.

Demolding Angle: It is advisable to be greater than 0.5° to enhance the surface quality of the workpiece and the stability of molding.

Holding pressure strategy: Controlling the crystallization rate during the holding pressure stage can reduce warpage and shrinkage differences.
