Introduction and Technical Structure
In ductwork networks, especially in rectangular duct systems, even the smallest leak at connection points can lead to significant energy waste and reduced system performance. Kian Fan Industrial Production Group, by producing elastomeric sealing tape, has provided a reliable and standard solution for sealing connections. The structure of this tape consists of elastomeric polymer materials that possess high elasticity.
These tapes are produced in rolls with standard widths to be easily applied to flange edges or connection seams. When two duct pieces or flanges are connected and bolts or cleats are tightened, the elastomeric tape is compressed and adapts its shape to the connection surfaces. This mechanism ensures that all potential gaps and surface irregularities are filled, creating an impermeable barrier against airflow.

Key Features and Advantages
The most important feature of Kian Fan's elastomeric sealing tape is its high adhesion power and permanent elasticity. This tape does not dry out, crack, or deform after installation and under pressure, maintaining the seal for a long period. Resistance to temperature fluctuations is another advantage of this product; the elastomeric tape retains its properties at different system temperatures (from extreme cold to the heat of warm air ducts).
These tapes are also resistant to moisture, fungi, and bacteria, which is important for ventilation systems in humid or hygienic environments. Using this sealing tape eliminates the need for time-consuming two-component mastics and drastically increases installation speed. Additionally, the smooth and uniform surface of the tape after installation gives the connections a clean appearance.

Specialized Applications
Kian Fan's elastomeric sealing tape has widespread applications in rectangular duct systems. Its primary application is in the TDC flange connection system, where the tape is placed between the flange profile and the duct edge to create a complete seal. In L-shape flange connections or angle iron flanges, this tape acts as a sealant.
Also, at the connection points of diffusers, dampers, and other auxiliary equipment to the duct, elastomeric sealing tape is used to prevent air leakage. In ventilation systems for hospitals and pharmaceutical industries where control of suspended particles and air leakage is highly sensitive, the use of high-quality sealing tapes is mandatory. This product is also used for insulating the seams of prefabricated ducts.

Conclusion
The elastomeric sealing tape of Kian Fan Industrial Production Group, relying on high-quality raw materials and advanced formulation, is a simple yet highly effective solution for guaranteeing sealing quality in ventilation systems. Choosing this product ensures reduced energy waste, increased acoustic comfort, and long-term durability of duct connections.
