  • Polyethylene Terephthalate (PET) Semi Dull TG645, also referred to as TG640N, is a thermoplastic polyester grade produced through a continuous polymerization process. Specifically engineered for textile and fiber applications, this semi-dull PET grade offers excellent processing performance, thermal stability, and optical consistency, making it ideal for high-speed spinning operations.

    With an intrinsic viscosity (IV) of 0.64 ± 0.015 dl/g, PET TG645 provides the optimal balance between flowability and mechanical strength during fiber formation. Its Diethylene Glycol (DEG) content of 1.4 ± 0.4 wt% enhances melt flexibility and improves the elasticity of finished fibers, contributing to better drawability and toughness.

    This grade features a Carboxyl End Group (CEG) concentration ≤32 Meq/kg, ensuring enhanced thermal durability and resistance to degradation during extrusion and post-processing. With a melting point of 255 ± 3°C, PET TG645 maintains dimensional integrity under high-temperature spinning and heat-setting conditions.

    The material exhibits high transparency, low toxicity, and excellent resistance to CO₂ permeability, making it suitable for nonwoven textiles, industrial fibers, and environmentally safe applications. The inclusion of Titanium Dioxide (TiO₂) at 0.34 ± 0.06 wt% imparts the characteristic semi-dull appearance, ideal for producing soft-finish and low-gloss fibers used in apparel and home textiles.

    Origin: Manufactured by Shahid Tondguyan Petrochemical Company (Iran) — a leading producer of high-quality PET resins for the textile and packaging industries.

Thermal Stability:
PET TG645 exhibits outstanding thermal stability, allowing it to withstand high processing temperatures without degradation. This durability is achieved through the controlled Carboxyl End Group (CEG) content ≤32 Meq/kg, ensuring the material maintains its mechanical integrity during fiber formation, extrusion, and heat-setting operations. As a result, it delivers consistent performance and long-term reliability in demanding textile processes.

High Transparency:
Engineered with an optimized molecular structure and low crystallinity, TG645 provides superior optical clarity that allows light to pass through efficiently. This property is essential for packaging films, fibers, and nonwoven materials requiring high visual transparency and enhanced aesthetic appeal.

High Mechanical Strength:
With an intrinsic viscosity (IV) of 0.64 ± 0.015 dl/g, TG645 demonstrates excellent mechanical strength and resistance to deformation. Its structural integrity ensures the production of durable fibers and filaments capable of withstanding physical stress, making it ideal for industrial textiles, apparel fabrics, and other performance-based applications.

Flexibility and Melt Behavior:
The Diethylene Glycol (DEG) content of 1.4 ± 0.4 wt% enhances melt elasticity and processing flexibility, enabling smooth polymer flow during fiber spinning. This property supports the formation of fine, uniform fibers with soft touch and superior flexibility, making it ideal for woven, knitted, and nonwoven textile production.

Semi-Dull Finish:
The inclusion of Titanium Dioxide (TiO₂) at 0.34 ± 0.06 wt% gives TG645 its signature semi-dull finish, preferred in the textile industry for achieving a matte, elegant surface appearance. This finish combines aesthetic refinement with mechanical reliability, catering to modern fabric design trends.

CO₂ Resistance:
Thanks to its dense polymer matrix, PET TG645 offers excellent resistance to CO₂ permeability, preventing gas transfer and maintaining internal pressure stability. This feature makes it suitable not only for textiles but also for packaging applications, such as bottles and films, where carbonation retention and product preservation are critical.

Textile Fibers and Filaments:
With an intrinsic viscosity of 0.64 ± 0.015 dl/g, PET TG645 is specifically engineered for producing polyester filaments and staple fibers that require high tensile strength, elasticity, and durability. Its molecular uniformity ensures excellent spinnability, thermal stability, and fiber resilience, making it ideal for industrial and apparel textiles where long-term performance is essential.

Nonwoven Fabrics:
In the textile and technical fabric sectors, TG645 is extensively used for manufacturing spunbond and meltblown nonwoven fabrics. These materials are widely utilized in hygiene products, medical textiles, filtration media, and geotextiles, offering a balance of softness, flexibility, and mechanical strength. The semi-dull finish enhances the visual and tactile quality of end products.

Packaging Applications:
Beyond its textile uses, TG645 demonstrates exceptional suitability for packaging materials such as beverage bottles, films, and food containers. Its transparency, high mechanical integrity, and resistance to CO₂ permeability make it an excellent choice for maintaining product freshness, clarity, and durability in bottled beverages and photographic films.

Industrial Applications:
Due to its thermal resistance and molecular stability, PET TG645 is also utilized in engineering plastics, coatings, and industrial composites requiring robust performance and consistent quality under demanding processing conditions.
