To achieve the “dual carbon” goals of peaking carbon emissions and achieving carbon neutrality, China has vigorously promoted the development of clean energy in recent years and accelerated the construction of photovoltaic power‑generation bases. Given that coastal regions boast robust economies and industries with high energy consumption, yet face severe constraints in available land resources, conventional onshore photovoltaic projects fall short of meeting demand. Consequently, leveraging marine resources to optimize the spatial deployment of photovoltaic systems can further advance the transformation and upgrading of the national energy mix.

To achieve the “dual carbon” goals of peaking carbon emissions and achieving carbon neutrality, China has in recent years vigorously promoted the development of clean energy and accelerated the construction of photovoltaic power‑generation bases. Given that coastal regions boast robust economies and industries with high energy consumption, yet face severe constraints in available land resources, conventional onshore photovoltaic projects are insufficient to meet demand. Consequently, leveraging marine resources to optimize the spatial deployment of photovoltaic systems can further advance the transformation and upgrading of the nation’s energy mix.

Currently, offshore photovoltaic power plants are categorized into two types: pile‑foundation and floating. Compared with the pile‑foundation design, floating systems offer greater cost‑effectiveness, broader application prospects, and improved environmental sustainability, making them likely to become the dominant technology in the future. A floating PV system comprises a floatation structure, photovoltaic modules, a mooring system, and an anchoring system. Given the harsh marine hydrological conditions, the system’s materials and components are subjected to long‑term challenges such as intense ultraviolet radiation, salt‑spray corrosion, and biofouling.

A conventional floating system must meet a 25-year service-life requirement; consequently, it faces stringent demands on buoyant materials to withstand seawater corrosion, ultraviolet radiation, and microbial attack. Currently, the mainstream buoyancy material—high-density polyethylene (HDPE)—is prone to degradation in offshore photovoltaic applications due to intense UV exposure and high-salinity corrosion, leading to discoloration, cracking, and even embrittlement and loss of mechanical strength in floatation pipes or pontoon modules, thereby compromising their ability to provide adequate structural support.

TiOEX titanium white chloride helps offshore photovoltaic systems remain robust over time.

Kuncai Technology’s TiOEX 8 series titanium dioxide boasts superior weather resistance and material compatibility. When incorporated as a pigment or additive into plastics, resins, and other materials, it enhances weatherability and toughness, enabling the production of buoyant HDPE through blending, extrusion, and molding processes. This ensures maximum retention of tensile strength, elongation at break, and impact resistance over a 25-year service life.

The TiOEX 8 series of titanium white pigments boasts high whiteness, imparting a clear, bright white hue to polyolefin products. Its excellent tinting strength effectively neutralizes the natural yellow tinge of resins and the yellowing that occurs during thermal processing, thereby extending the service life of floating offshore photovoltaic materials and enhancing the economic viability of offshore solar installations.

The TiOEX 8 series of titanium white pigments exhibits excellent processing performance, delivering an outstanding user experience. Its superior product characteristics enable maximized masterbatch loading levels, resulting in high production efficiency, reduced energy consumption, and increased output per unit time. These efficient manufacturing advantages are well positioned to meet the rapidly growing market demand for floating offshore photovoltaic materials.

Thanks to the environmentally friendly process advantages of the extraction method, coupled with Kuncai’s initiatives to achieve zero‑carbon electricity and low‑carbon energy use, the TiOEX 8 series titanium dioxide—designed as a low‑carbon, sustainable product—helps reduce the environmental footprint across the industry’s upstream and downstream value chain, thereby advancing sustainable development.

Going forward, Kuncai Technology will align with the global trend toward low-carbon and environmentally friendly development, guided by downstream market demand, and continue to pioneer cutting-edge technologies in the titanium dioxide sector to deliver entirely new user experiences. The TiOEX 8 series of titanium dioxide pigments will meet the growing market needs for recyclability, ease of recycling, biodegradability, and waste reduction in plastic products by continuously enhancing product performance.
