Technical FAQ: 6618 Titanium Dioxide in Paper Applications
Q1: What is the crystal form of 6618 titanium dioxide?
A: 6618 is an anatase-type titanium dioxide, optimized for high opacity and whiteness in paper. Anatase offers better light scattering in thin sheet substrates than rutile in many papermaking processes.
Q2: How does oil absorption impact paper properties?
A: Lower oil absorption (≤22g/100g for 6618) improves paper smoothness, reduces ink penetration, and enhances print clarity. This is a critical parameter for magazine, label, and high-gloss packaging grades.
Q3: What is meant by titanium dioxide LD50?
A: LD50 refers to the “lethal dose, 50%” toxicity benchmark. Pure anatase and rutile TiO₂ for industrial use are considered non-toxic (oral LD50 >10,000 mg/kg in rats), making them extremely safe for paper and packaging applications.
Q4: What are the main differences between r902 titanium dioxide and 6618?
A: R902 is a rutile pigment mainly used in coatings/paints for durability and weather resistance. 6618, as anatase, is engineered for ultrafine distribution and maximum brightness in paper, with slightly higher oil absorption but lower cost per function for printable papers.
Q5: Can 6618 titanium dioxide be supplied in titanium dioxide bulk quantities?
A: Yes, it is available in bulk packaging (25kg bags to 1MT super sacks) for global customers with flexible order sizes and shipment options.
Q6: What is the importance of hydrophilic surface treatment?
A: Hydrophilic treatment (typically with silica or alumina) increases 6618's affinity for cellulose fibers, thus boosting pigment retention in the paper web and reducing wastage.
Q7: Which environmental and safety standards does 6618 titanium dioxide comply with?
A: It adheres to ISO 591-1, RoHS, FDA (for food packaging), and GB standards. Heavy metals are controlled <10ppm, and products are certified by SGS/TUV for restricted substances.
Conclusion: Future Trends & Trusted Sourcing of 6618 Titanium Dioxide
- Demand for high-purity 6618 titanium dioxide will intensify with Global EPR (Extended Producer Responsibility) norms on packaging whiteness and recyclability.
