Product Basics

Introduction

PETG Gray GY502 is a high-concentration, high-performance PETG gray coloring material. This product presents a textured gray color, with excellent physical stability and superior coverage. Its parameters are density 1.3-1.35, melt index 3-5, active content 35%, moisture 0.1-0.3%, and recommended addition amount is 2-5%. It is widely applicable to substrates such as PET, PETG, and PC, not only performing excellently in 3D printing but also perfectly compatible with traditional plastic processing methods such as injection molding, blow molding, and extrusion, making it the preferred solution for those seeking high-end texture and stable processing.

Product Features and Benefits

- Gold Molten Finger 3-5: perfectly matches 3D printing needs, extrudes smoothly without plugs, reduces wire drawing seepage, and ensures interlayer adhesion
- Ultra-low moisture control: Prevents bubbles, surface roughness, and interlayer cracking from the source, improving printing success rate
- Stable filament pulling: Optimized for extrusion filament pulling, not easy to break, with small diameter tolerance, suitable for mass production of 3D printing materials
- High concentration cost reduction: Only 2-5% is needed to achieve perfect coverage, reducing production costs and preventing nozzle clogging
- High-quality and durable texture: Effectively covers print layer lines, retains the high toughness and chemical resistance of PETG, suitable for high-precision functional parts and appearance parts

- This product is independently manufactured by our company, or customized and produced by large domestic and international factories, with full quality control and high batch stability.
- Specifically designed for PET, PETG, PC, and their alloys, with excellent dispersibility, without significantly changing the original physical properties of the substrate
- Multi-process compatibility: Compatible with injection molding, blow molding, extrusion, and other processing technologies, producing finished products with uniform color and no bubble silver threads

TYPICAL APPLICATION FIELDS

Core application: 3D printing field
- Produce 1.75mm/2.85mm specification FDM 3D printing gray filament
- Directly used for 3D printing, compatible with mechanical parts, architectural models, figure base molds, and post-coloring prototype pieces

Other processing fields
- Injection Molding Processing: Coloring of PET/PETG/PC material appliance housings, automotive interior parts, and daily plastic products
- Blow molding processing: Gray coloring of PETG packaging bottles and transparent containers
- Extrusion processing: Coloring of PETG sheets, profiles, and tubes during extrusion, with full and even color

Processing Operation Recommendations

- 3D Printing/Filament Extrusion: It is recommended to dry for 4-6 hours at 60-65°C before processing. The suggested printing temperature is 230-250°C, the heated bed 70-80°C, and the printing speed 30-60mm/s.
- Injection molding/extrusion: Mix with this colorant at a ratio of 2-5% and dry thoroughly according to the conventional PET/PETG process before processing
