Products Description
What is Co-polyester (PETG/PCTG)?
Co-polyester, short for copolymerized polyester, is a synthetic material derived from the polymerization of cyclohexanedimethanol (CHDM), other polyacids, and polyols. This unique chemical structure and outstanding performance of PETG/PCTG make it stand out in many fields.
Key Properties of Co-polyester
Exceptional Clarity & Aesthetic Appeal
With high light transmittance, Co-polyester offers crystal-clear transparency, making it ideal for applications where visual appeal is crucial, such as cosmetic packaging and food containers. Its smooth surface also enhances printing capabilities, allowing for vibrant, durable graphics.
Superior Chemical & Impact Resistance
Co-polyester's robust molecular structure provides excellent chemical resistance, ensuring it withstands exposure to oils, solvents, and other harsh substances. Additionally, its good toughness makes it resistant to cracking or shattering, even in demanding environments.
Temperature Stability
A certain grade of Co-polyester exhibits excellent temperature resistance, maintaining its structural integrity across a wide temperature range. This makes them suitable for applications like small household appliances and medical equipment, where heat resistance is critical.
Compliance & Safety
PETG/PCTG is certified by authorities such as the FDA (food contact approval), RoHS, and REACH, ensuring it meets strict safety and environmental standards. Importantly, it is BPA-free, making it a safe choice for food and beverage packaging.
PCTG is synthesized using advanced polymerization techniques, incorporating CHDM (Cyclohexanedimethanol) or other polyacids and polyols. This formulation enhances its performance compared to traditional materials like PETG:
- Higher Heat Resistance: PCTG outperforms PETG in temperature resistance, making it suitable for applications requiring exposure to elevated temperatures.
- Enhanced Processability: Its melt flow properties enable easy extrusion and molding, reducing production costs and improving efficiency.
- Compliance & Safety: PCTG is certified with RoHS, REACH, and BPA-free standards, ensuring adherence to global safety regulations.
To cater to varied industry demands, Co-polyester PCTG is available in specialized grades:
- HF500: Ideal for applications requiring high clarity and impact resistance, such as consumer goods.
- HF501M: Offers improved processability for complex molding requirements.
- HF503 & HF503C: Designed for enhanced temperature resistance, making them suitable for small appliances and medical devices.
