Global consumption of titanium dioxide exceeded 6.2 million tons in 2023, with strong growth predicted in paints, plastics, inks, and specialty applications. r6618 tio2, a rutile-grade TiO₂ renowned for durability and gloss, is showing surging demand, especially in architectural and industrial coatings. Key global suppliers include Tronox, Chemours (Ti-Pure), Lomon Billions, TionA, Hitox, TINOX, and emergent regional producers delivering competitive custom grades to meet strict end-user needs.

Below is a comprehensive comparison table of leading r6618 tio2 technical parameters sourced from industry datasheets and laboratory test results.

r6618 tio2 is typically produced via the chloride process, renowned for yielding high-brightness, low-impurity rutile grades. The standard process involves:

• Titanium Feedstock Selection: High-purity ilmenite or rutile ore is sourced and pretreated for maximum TiO₂ recovery.
• Chlorination: Ore is converted to titanium tetrachloride (TiCl₄) in a fluidized-bed reactor, utilizing chlorine gas and reducing agents.
• Oxidation: TiCl₄ vapor is oxidized at 1000-1200°C, forming ultra-fine, pure TiO₂ particles.
• Controlled Cooling and Milling: Rapid cooling, micronization, and controlled CNC wet-milling adjust crystal size, surface area, and optical properties.
• Surface Coating: Inorganic (alumina, silica) and sometimes organic treatments optimize dispersibility, weatherability, and compatibilities for various resins.
• ISO/ANSI Testing: Reference tests for whiteness (ISO 787/24), hiding power (ASTM D476), oil absorption (ISO 787/5), and specific gravity validation.

• Advanced chloride process reactor automation for product consistency
• Multistage CNC mixing for precise surface coating control
• Laser particle size analysis for sub-micron TiO₂ (D₅₀<0.25μm)
• Inline XRF and ISO-certified whiteness testing labs

TITANIUM DIOXIDE NTR-606 TO BE USED IN PAINT INDUSTRY (view product) is engineered to meet the highest standards for exterior and interior coatings. Typical physical and chemical parameters are provided below:

The superior whiteness, tinting strength, and low oil absorption impart NTR-606 with a significant performance edge over conventional tio2 types in high-gloss, color-critical paint industry applications. ISO 591-1:2000 and FDA certifications further bolster market trust.

• r6618 tio2 boasts ultra-high opacity, UV stability, and minimal yellowing/fracturing, suitable for premium coatings (paints, inks).
• caco3 tio2 blends offer cost savings, but at lower hiding power and weatherability—best for indoor or low-exposure products.
• Tinox tio2 has niche demand in elastomers and automotive plastics, where anti-chalking and pigment mobility are valued.
• Tiona tio2 grades are popular for mid-tier paints, with reasonable tinting and processability.
• Hitox tio2 (beige/off-white) is sought for hiding/concealing darker substrates where color uniformity compensates for lower brightness.

OEMs worldwide increasingly choose r6618 tio2 for its proven results in harsh UV environments, advanced architectural schemes, and energy-saving (infrared reflective) formulations.

Recent projects by certified partners (references on request) demonstrate usage in petrochemical coating refurbishments, corrosion protection for offshore structures, and smart materials for renewable energy panels. Robust after-sales and support includes customized product selection, on-site training, and technical consulting.

• ISO 9001/14001 Quality and Environmental Management certification
• Compliant with ANSI, ASTM, and national regulatory standards for pigment safety and performance
• Batch traceability & full COA documents supplied with every shipment
• Warranty: Minimum 24-month shelf life under standard storage; extended warranty available upon request
• Technical/Customer Support: 24/7 response, formulation guidance, and failure analysis

Typical r6618 tio2 delivery cycle is 7–15 working days, depending on quantity and logistic requirements. Customized grades or private label services are also available for qualified enterprise buyers. Each batch passes XRF element analysis, rapid colorimetric tests, and ISO whiteness/hiding power checks.

The ongoing evolution of r6618 tio2 and allied titanium dioxide grades is fueling breakthroughs in coatings, plastics, and applied materials engineering. With technical leadership in formulation, rigorous compliance with global standards (ISO, FDA, ANSI), and robust customer support, r6618 tio2 is endorsed by leading coatings manufacturers, plastics processors, and specialty chemical suppliers worldwide.
