3. Physical & Chemical Properties
- State: Solid semi-dull chips at room temperature
- Production Process: Produced via chemical recycling technology, converting post-consumer PET waste into food-contact grade polyester resin. The semi-dull grade is modified with titanium dioxide for reduced luster.
- Key Properties: Low moisture content, low carboxyl end group, low metal/ash impurities, stable viscosity, consistent color values
- Stability: Good thermal stability during spinning and extrusion; suitable for standard PET processing conditions
4. Applications
- Spinning for semi-dull recycled polyester fibers (textile, apparel, nonwovens)
- Recycled PET yarn and filament production
- Regenerated fiber and textile manufacturing
- General semi-dull polyester fiber applications
5. Packaging & Storage
Packaging: 1000kg bags
Storage Conditions: Store in a cool, dry, well-ventilated area. Keep away from moisture, direct sunlight, and incompatible materials.Handling Precautions: Avoid dust inhalation. Use appropriate personal protective equipment (gloves, goggles) when handling.
