I. PETG CF5 Granules
PETG CF5 Granules are an advanced carbon fiber reinforced thermoplastic composite material, produced by compounding a PETG matrix with 5% carbon fiber through a specialized pelletization process. This category of CF Thermoplastic Compounds significantly enhances the mechanical strength and dimensional stability of the material while maintaining the excellent transparency and processability of PETG. It is particularly suitable for manufacturing high-performance 3D Printing Filaments, providing an ideal material solution for engineering-grade 3D printing applications.
II. PETG CF5 Granules Key Properties
1. Excellent Interlayer Adhesion Strength
3D Filaments produced from PETG CF5 Granules achieve an interlayer adhesion strength of 8.5 MPa during printing, approximately 35% higher than standard PETG, ensuring exceptional structural integrity of printed parts along the Z-axis. This is a notable advantage of CF Thermoplastic Compounds.
2. Low Warpage and High Dimensional Stability
The incorporation of carbon fibers reduces the material’s thermal shrinkage to below 0.5%, with a linear coefficient of thermal expansion of 3.2×10⁻⁵/°C, significantly outperforming unfilled PETG and ensuring dimensional accuracy when printing large components with 3D Filaments.
3. Good Chemical Resistance
This CF Thermoplastic Compounds exhibits good resistance to common chemicals such as alcohols and oils, with a weight change rate of less than 0.3%, making it suitable for manufacturing functional parts that may encounter chemical environments.
4. Balanced Mechanical Properties
PETG CF5 Granules offer balanced properties with a tensile strength of 58 MPa and a flexural modulus of 3200 MPa, while maintaining an elongation at break above 8%, providing 3D Filaments with both rigidity and moderate toughness.
5. Optimized Printing Flowability
The Melt Flow Index remains stable between 12-18 g/10min (240°C/2.16kg), with a wide printing temperature window (230-250°C), ensuring stable extrusion of this CF Thermoplastic Compounds material across different 3D printers.
III. Primary Applications
PETG CF5 Granules are primarily used to produce high-performance 3D Filaments, suitable for medical device housings, automotive functional components, electronic device brackets, industrial jigs, and outdoor equipment. This type of CF Thermoplastic Compounds is particularly suited for end-use applications requiring good mechanical strength, dimensional stability, and chemical resistance.
IV. PETG CF5 Granules Application in Medical Device Housing Manufacturing
A medical device manufacturer utilized 3D Filaments produced from PETG CF5 Granules to manufacture housings for portable monitors. The housing needed to withstand impacts during daily transport and resist repeated disinfection with 75% alcohol. Housings printed with this material passed a 1.2-meter drop test, achieved a surface hardness of HB grade, and showed no cracking or deformation after 500 alcohol wipe cycles, while being 20% lighter than traditional ABS housings. This application demonstrates the practical value of CF Thermoplastic Compounds in the medical device sector.
