FAQ

1. Who are we?
Anhui Liluan Technology Co., Ltd. is a direct, specialized manufacturer of high-performance rock wool insulation materials. Established in 2009, our facility features advanced automated production lines with an annual capacity of 50,000 tons, delivering reliable thermal and acoustic solutions for global industrial and commercial projects.

2. What is the maximum service temperature of our rock wool blankets, and where are they primarily applied?
Our industrial-grade rock wool blankets are engineered to withstand continuous service temperatures up to 650°C without structural sagging, fiber breakdown, or premature binder degradation. They are highly specified for thermal insulation and energy conservation in extreme environments, including: Heavy industrial boilers and furnaces, Large-diameter high-temperature steam pipelines, Petrochemical storage tanks, and oil refinery towers.

3. How do our blankets perform when wrapping curved surfaces, and what facing reinforcements do we offer?
Utilizing advanced automated spinning and stitching technology, our stone fibers maintain exceptional tensile strength and internal cohesion. This allows the blankets to be wrapped tightly around complex, cylindrical, or irregular geometries without tearing, cracking, or flattening out. To match your specific engineering blueprints, we offer three structural variations:
1) Wired Mats (Mesh Stitched): Stitched with galvanized or stainless steel wire mesh for heavy-duty structural stability on vibrating equipment.
2) Foil-Faced (FSK): Laminated with reinforced aluminum foil to serve as an excellent radiant heat reflector and a zero-permeability vapor barrier for condensation control.
3) Bare Rolls: Standard unfaced rock wool blankets for economical, high-performing core insulation.

4. Why should you buy from us and not from other suppliers?

Unlike generic trading companies or standard suppliers, we offer definitive technical advantages for industrial applications:

High-Temperature Stability: Our industrial-grade blankets are engineered to withstand continuous service temperatures up to 650°C without structural sagging or premature binder degradation.
