The technical data sheet (TDS) of Sinopec Yizheng Chemical Fibre FG600 PET material from Sinopec Yizheng Chemical Fibre corporation, if there are differences, please refer to the official website of Sinopec Yizheng Chemical Fibre.
Features & Benefits
-
Stable Intrinsic Viscosity Range: Viscosity stably controlled at 0.675±0.02 dl/g with uniform melt fluidity, ensuring zero batch fluctuations during blow molding and extrusion processes, thereby reducing shutdown and adjustment frequencies.
-
Extremely Low Dust and Impurity Content: Dust content ≤0.01 wt%, substantially minimizing black spots and gel particle defects in hollow bottles and film products, enhancing finished yield rates, and suiting high-end transparent packaging production.
-
Controllable Low Moisture Content Indicator: Base moisture content ≤0.4%, which, when paired with standard drying processes, effectively suppresses molding hydrolysis and prevents issues like whitening and toughness reduction in finished items.
-
Constant Melting Temperature Window: Standard melting point of 261±3°C with a broad thermal processing range, adapting to all mainstream processing equipment including single/twin-screw extrusions and one-step/two-step blow molding.
-
Original Factory Stable Batch Control: Manufactured via Sinopec Yizheng Chemical Fibre’s standardized continuous production lines, with COA inspection reports supplied per batch, ensuring traceability for cross-border export orders and meeting stable supply demands of global packaging buyers.
-
Basic Solvent Resistance: Resists most daily chemical solvents and weak acids/bases at room temperature, preventing packaged products from being swollen or corroded by contained liquids, and suiting food and daily chemical filling conditions.
Applications
-
Food and Beverage Packaging Industry: Carbonated beverage bottles, mineral water bottles, fruit drink hollow bottles, edible oil transparent packaging bottles, and condiment food sealing containers; compliant for food contact with no harmful substance leaching.
-
Daily Chemical and Personal Care Packaging Field: Transparent plastic bottles for shampoo, shower gel, and skincare products, disinfectant dispensing containers, and cosmetic sample hollow packaging, with high-purity raw materials ensuring transparent, flaw-free container appearances.
-
Film and Sheet Extrusion Processing: Single-layer PET packaging films, food thermoforming sheets, and composite packaging substrates, where uniform melt performance ensures consistent film thickness and prevents tearing during stretch forming.
-
General Industrial Packaging Products: Small chemical reagent dispensing barrels, transparent plastic storage containers, and gift packaging transparent shells, balancing rigidity and clarity to meet lightweight industrial packaging demands.
-
PET Strapping and Sheet Extrusion Substrates: Relying on favorable melt strength and tensile performance, widely suited for processing medium-to-low strength plastic strapping bands and various extruded sheet applications.
Frequently Asked Questions (FAQs)
Q1: Is drying treatment mandatory before processing FG600 PET chips? What are the recommended drying parameters?
A: PET materials are highly susceptible to high-temperature hydrolysis. Even with a raw material factory moisture content ≤0.4%, thorough drying is required before machine loading. Standard industry process: hot air dehumidifying dryer at 160–170°C for 4–6 hours, controlling post-drying moisture content below 0.005% to effectively prevent haze whitening and brittle cracking in blow-molded bottles and film products.
Q2: How should one select and differentiate between FG600 PET, high-viscosity PET, and PC materials in packaging applications?
A: FG600 is a low-to-medium viscosity standard bottle-grade PET offering cost advantages and fast molding speeds, making it ideal for disposable food and daily chemical transparent packaging; high-viscosity PET (viscosities above 0.8 dl/g) is predominantly used for large-capacity pressure-bearing containers; PC provides superior heat resistance and impact strength at a higher cost, mainly utilized for mother-and-baby water cups and high-temperature food containers, whereas routine liquid packaging does not require PC replacement.
Q3: Does Sinopec FG600 PET hold international export compliance certifications (RoHS, food contact standards)?
A: This grade is a food-contact-grade polyester chip for which the original factory can supply corresponding testing reports, complying with EU RoHS 2.0 restricted substance standards, US FDA food contact specifications, and China GB food contact plastic standards. It fulfills cross-border export packaging compliance requirements for Southeast Asia, Europe, and America, with MSDS and COA documents accompanying each shipment.
Q4: Can FG600 PET scrap regrind be blended with virgin raw materials for reproduction?
A: Clean FG600 scrap crushed material free of oil stains or contamination from other plastics can be blended with virgin chips at a ratio of 10% to 20%. Blending ratios exceeding 30% will reduce melt viscosity, resulting in diminished container wall thickness and reduced toughness, and thus high-percentage recycling reuse for high-end food packaging is not recommended.
