High-performance thermal insulation products engineered for extreme environments.
Located in Jiujiang, Jiangxi Province, China Beihai is a premier high-tech enterprise dedicated to the R&D, production, and global supply of high-performance basalt continuous fiber. As a pioneer in the heat resistance protective sleeving industry, we integrate advanced equipment manufacturing with material science to provide world-class basalt fiber products.
Our facility serves as a hub for innovation, transforming volcanic rock into high-tensile, thermal-shielding solutions for the most demanding sectors, including aerospace, automotive, and heavy infrastructure.
Navigating the complex landscape of high-temperature protective sleeving and basalt fiber applications.
In the modern industrial era, thermal management is no longer just a safety requirement—it is a performance multiplier. As machinery operates at higher speeds and voltages, the risk of thermal degradation in wiring and hoses increases exponentially. Traditional fiberglass often falls short in chemical stability, while carbon fiber can be prohibitively expensive. This is where Basalt Fiber Protective Sleeving emerges as the superior "middle-ground" solution, offering better thermal range than E-glass and higher chemical resistance than many synthetic polymers.
With nearly a decade of specialization, China Beihai possesses the Experience and Expertise to handle complex pultrusion and weaving specifications that generalist textile mills cannot match.
Our Jiangxi factory controls the entire supply chain—from the melting of raw basalt rock to the final braiding of the heat resistance sleeving. This ensures a stable Pricelist and Reliability for long-term wholesale partners.
We provide Information Gain by developing proprietary surface treatments that enhance the alkali resistance of basalt fibers, making them ideal for concrete reinforcement in addition to thermal sleeving.
The global shift toward Green Manufacturing has placed basalt fiber in the spotlight. Unlike glass fiber, basalt is 100% natural and inert, requiring no chemical additives during the melting process. Trend analysis shows:
Used to protect hydraulic lines from flash fires and corrosive chemical spills, ensuring operational continuity in harsh environments.
Our heavy-duty sleeves act as a barrier against molten metal splash and intense radiant heat near blast furnaces.
Protective sleeving for wiring in wind turbine nacelles, where friction and fluctuating temperatures are constant challenges.
Enterprises worldwide are seeking Wholesale Suppliers who can offer more than just a product. The demand is for a partnership that includes:
Our basalt heat resistance sleeving can operate continuously at 700°C, with short-term exposure limits reaching up to 900°C.
Basalt fiber offers significantly higher tensile strength, better chemical resistance (especially to alkalis), and a wider thermal operating range.
Yes, as a direct manufacturer, we offer custom internal diameters from 2mm to 150mm and various surface coatings (Silicone, Acrylic, etc.).
