TG-645

• Thermal stability  

It refers to TG645’s ability to withstand high temperatures without degrading. This is achieved through a controlled carboxyl end group (CEG) content (≤32 Meq/kg). It is crucial for maintaining material performance during high-temperature processing and ensuring durability in fiber formation and other applications.

• High transparency  

TG645 offers high transparency due to its optimized molecular structure and low crystallinity. That allows light to pass through efficiently. This property is important in applications such as packaging and films, where clarity and visibility are essential, enhancing product appeal and functional usability.

• High mechanical strength

The high intrinsic viscosity (0.64 ± 0.015 dl/g) of TG645 ensures excellent mechanical strength. This attribute is vital for producing durable fibers and filaments capable of withstanding physical stress. That makes the material ideal for textiles and other applications requiring toughness and longevity.

• Flexibility and melt properties  

The Diethylene Glycol (DEG) content (1.4 ± 0.4 wt%) in TG645 improves flexibility and melt behavior. That allows the polymer to flow smoothly during fiber formation. This feature ensures efficient processing and production of fine, flexible fibers, enhancing the usability in textile and nonwoven applications.

• Semi-dull finish  

The addition of titanium dioxide (0.34 ± 0.06 wt%) gives TG645 a semi-dull finish. This aesthetic attribute is important in textile production, where a matte or reduced-gloss appearance is preferred for certain fabrics, providing a soft, elegant look while maintaining functional performance.

• Resistance to CO2

TG645’s resistance to CO2 permeability is due to its dense polymer matrix, which prevents gas molecules from passing through. This feature is important in applications like beverage bottles, where it helps maintain carbonation and preserve the quality of the contents, ensuring long shelf life.

TG645, with its optimized intrinsic viscosity of 0.64 ± 0.015 dl/g, is highly suitable for producing various types of polyester filaments and fibers. Its high mechanical strength and durability make it ideal for textiles, especially in applications requiring strong, resilient fibers.

In the textile industry, TG645 is used to produce spunbond nonwoven fabrics, which are employed in a wide range of applications including hygiene products, medical textiles, and geotextiles. The filaments and fibers made from TG645 provide strength, flexibility, and a semi-dull finish, making them suitable for both industrial and consumer fabric uses.

Beyond textiles, TG645 is also versatile in packaging applications. Its superior mechanical strength, transparency, and resistance to CO2 permeability make it ideal for beverage bottles and photographic films, where durability and gas barrier properties are critical for maintaining product quality and longevity.
