Misconception 1: The higher the titanium content of TiO₂, the higher the whiteness?
Truth: Whiteness is a comprehensive property, not determined by titanium content alone.
Titanium content is only one of several influencing factors. Impurity control, particle size, and surface treatment are equally critical. LB Snow Lotus titanium dioxide is engineered through application-specific, fine chemical process control to achieve higher whiteness and hiding efficiency in downstream applications at a reasonable titanium content—avoiding unnecessary cost increases caused by blindly pursuing ultra-high content.
Misconception 2: Titanium dioxide makes paper brittle and reduces paper quality?
Truth: Paper strength is influenced by multiple factors, not by TiO₂ alone.
As a filler, TiO₂ occupies part of the fiber bonding space and can affect strength to some extent. However, filler dispersion, fiber condition, and drying processes often have a more significant impact. The key lies in selecting TiO₂ with good dispersibility, controlling dosage properly, and matching suitable process conditions—so that optical properties are enhanced while physical strength and toughness are retained, achieving optimal overall quality.
Misconception 3: Titanium dioxide reacts with paper components to form harmful substances?
Truth: TiO₂ is chemically stable; safety depends on purity and compliance.
Titanium dioxide is highly stable and inert. It does not undergo harmful chemical reactions with cellulose, other fillers, or chemical additives in paper. What matters is using high-quality TiO₂ that complies with relevant safety regulations and applying it under standardized conditions. LB Snow Lotus TiO₂ strictly adheres to product safety and compliance standards, introducing no harmful substances and ensuring safe use in all types of paper production.
Misconception 4: The more TiO₂ added, the higher the opacity?
Truth: Opacity does increase—but with diminishing returns.
Initial additions significantly improve opacity, but beyond a certain level, gains become marginal while costs rise and paper properties may be adversely affected. Within an optimal dosage range, our high-hiding-power products help customers achieve target opacity at lower addition levels, delivering both cost reduction and efficiency gains.
Misconception 5: TiO₂ causes decorative base paper to turn gray after lamination and light exposure?
Truth: High-quality TiO₂ is actually key to preventing graying.
Graying after exposure is closely related to TiO₂ dispersion uniformity, impurity levels, and surface treatment. High-quality rutile TiO₂ with proper surface treatment (such as inorganic and organic coatings) not only avoids graying but is essential for maintaining whiteness and opacity.
