AB-1200 is a high-performance modified precipitated barium sulfate engineered specifically for biaxially oriented polyethylene terephthalate (BOPET) film applications. Developed by Yunfu Hongzhi New Materials Co., Ltd. using an exclusive sulfuric acid process, it features ultra-narrow particle size distribution (D50 = 1.2 µm), exceptional purity (≥98.0 wt% BaSO₄), and superior surface modification for optimal polymer compatibility. Its low oil absorption (11 g/100g), high whiteness (L-value ≥99.0), neutral pH (8.5), and matched refractive index with PET enable dramatic haze reduction and sustained gloss retention in thin films. Widely adopted in high-value flexible packaging, metallized film, and label stock manufacturing, AB-1200 delivers reliable anti-blocking and easy-opening functionality without compromising optical clarity or equipment integrity.
1. Ultra-fine & uniform D50 of 1.2 µm ensures consistent dispersion and eliminates optical defects in BOPET films.
2. Surface-modified particles exhibit excellent compatibility with polyester resins, enhancing interfacial adhesion and mechanical stability.
3. High purity (≥98.0% BaSO₄) and absence of sulfides, odors, or impurities guarantee batch-to-batch reliability and regulatory compliance.
Store in a cool, dry, well-ventilated area away from direct sunlight and moisture. Shelf life is 24 months when sealed and stored under recommended conditions. Transport as non-hazardous general cargo; avoid exposure to rain or extreme temperatures during transit. For optimal dispersion, pre-dry if ambient humidity exceeds 60% RH; use high-shear mixing for masterbatch preparation. Always wear NIOSH-approved dust mask, safety goggles, and gloves when handling to prevent inhalation or eye contact; avoid generating airborne dust.; Storage condition: bag; Shelf life: bag; Pack size: bag
