Hontai Global Limited is a Hong Kong-based advanced-materials enterprise working on the R&D, engineered refinement and worldwide sale of TiO₂-based core-shell functional materials. We are, first of all, a particle engineering house: the material is specified for the process it will run in, not sold as a universal powder.
Our team brings more than 25 years of titanium dioxide experience, most of it in fibre-grade anatase for in-polymer (polymerisation) applications across polyester, nylon and the other major chemical fibres. That experience is what shaped our approach. Conventional TiO₂ particles impose hard limits on a process — they agglomerate under shear, scatter light unevenly and sit poorly in the polymer matrix — and those limits are a materials problem, not a pricing problem.
Core-shell architecture is our answer. In a core-shell particle, a TiO₂ core is enclosed in an engineered shell whose composition, thickness and surface energy are chosen for the host system. The result is a material that disperses more completely, delivers the optical behaviour the application actually needs — dulling, brightening or opacifying — and interacts predictably with the polymer it is added to. Particle surface engineering is the discipline; a grade that performs on your line is the deliverable.
Headquartered in Causeway Bay, Hong Kong, we bridge materials R&D and commercial production. Specification, qualification, documentation and international sales are handled from Hong Kong, while volume is produced with our tier-one manufacturing partners — principally our sister company, Huai'an Hongyang Titanium Industry Co., Ltd., in Jiangsu, China, a National High-and-New-Technology Enterprise and a Jiangsu SRDI SME (Specialised, Refined, Distinctive and Innovative).
Every shipment leaves specified for a process and documented for a border: TDS, GHS-format SDS, lot-by-lot COA, certificate of origin and packing documents, prepared correctly the first time.
What an engineering partner does that a supplier does not
Particle engineering
Core chemistry, shell composition and surface energy are specified together, so the material behaves in your line and not only on a datasheet.
Specification
We translate your target brightness, residue limit and addition route into a grade and a datasheet you can sign off.
Trial & sampling
Samples with the COA of the exact lot, and a trial plan that measures filter pressure and spin breaks, not just whiteness.
Documentation
TDS, SDS, COA, certificate of origin and packing documents prepared correctly the first time, so customs does not stall.
Market feedback
Raw-material and process findings travel back to production, so recurring issues get fixed rather than re-explained.
Hongyang Titanium — a leading chemical-fibre titanium dioxide producer in mainland China
Hontai Global directly connects global clients to our manufacturing sister company, Huai'an Hongyang Titanium Industry Co., Ltd. Operating dedicated chemical-fibre anatase production lines in Jiangsu, the facility is a recognised National High-and-New-Technology Enterprise (HNTE) and a Jiangsu SRDI SME (Specialised, Refined, Distinctive and Innovative).
While the group's own production capacity underpins volume stability and consistent quality, Hontai Global manages technical specification alignment, export documentation and international sales from Hong Kong.
