PET-BG821

PET-BG821 Bottle-Grade Granules | High-IV Polyethylene Terephthalate

Polyethylene Terephthalate (PET) is a premier, highly recyclable thermoplastic polyester prized for its durability and optical clarity. Among bottle-grade resins, PET-BG821, manufactured by Shahid Tondgooyan Petrochemical Company, represents the pinnacle of performance for stretch blow molding applications.

Engineered with a high intrinsic viscosity (IV) of $0.82 \pm 0.02$ dl/g and a strictly controlled low Diethylene Glycol (DEG) content (≤1.5 %wt), this grade delivers exceptional mechanical strength and a robust barrier against oxygen and carbon dioxide. The specific advantage of BG821’s low DEG content is its superior thermal stability during processing, which minimizes acetaldehyde (AA) generation—crucial for preserving the taste profile of sensitive beverages like mineral water.

Frequently Asked Questions (FAQ)

1. What is the difference between PET-BG821 and PET-BG825? While both grades feature a high IV of 0.82 dl/g, the key distinction lies in the DEG content. PET-BG821 has a lower, tighter DEG specification (≤1.5%) compared to BG825 (max 2.0%). This lower DEG provides superior thermal stability, reduces yellowing during processing, and crucially, lowers the generation of acetaldehyde (AA). This makes BG821 the superior choice for premium bottled water and light-flavored beverages where taste neutrality is paramount.
2. Is the PET-BG821 supplied a prime-grade material? Yes. Shobeir Shimi strictly supplies prime, reactor-grade PET-BG821 produced by Shahid Tondgooyan Petrochemical Company. The material is delivered in its original packaging as natural, virgin pellets and fully complies with international food contact regulations, including FDA and EU standards.
3. Is PET-BG821 environmentally sustainable and recyclable? Absolutely. PET (Resin Identification Code #1) is globally recognized for its infinite recyclability. Bottles manufactured from BG821 can be fully reintegrated into the circular economy through mechanical or chemical recycling, producing high-quality rPET suitable for fibers, strapping, thermoforming, or closed-loop food containers.
4. What is the Minimum Order Quantity (MOQ)? Our standard minimum order quantity is one full truckload (approximately 22 metric tons) or one standard shipping container for international exports. We evaluate smaller industrial volumes on a case-by-case basis.
