Phenolic insulation board
**Introduction to Phenolic Insulation Board: A Revolutionary Product Concept**
Phenolic insulation board is a cutting-edge, non-combustible and fire-resistant insulation material made from phenolic foam. It is a rigid, closed-cell foam created by adding foaming agents, curing agents, and other additives to phenolic resin. This innovative material stands out for its excellent fire resistance, low smoke emission, and high-temperature stability. It effectively overcomes the limitations of traditional foam plastics, which are flammable, produce excessive smoke, and deform under heat, while still maintaining the lightweight and easy-to-install properties of conventional foam insulation.
**Key Advantages of the Product**
1) **Outstanding Fire Performance**
The insulation layer is composed of phenolic foam and can be used in combination with other materials for building insulation. It meets the national fire protection standard of Class A, significantly reducing the risk of external insulation fires. The material can withstand temperatures ranging from -250°C to +150°C, making it highly versatile for various applications.
2) **Excellent Thermal Insulation and Energy Saving**
With a thermal conductivity of approximately 0.023 W/(m·K), the phenolic insulation board offers superior insulation performance compared to most inorganic and organic insulation products currently available on the market. This results in significant energy savings and improved thermal efficiency.
3) **Wide Range of Applications**
This insulation material is not only suitable for traditional exterior insulation systems but also for composite panels with decorative finishes. It can be used to create fire barriers in EPS/XPS/PU exterior wall insulation systems, as well as for fire protection in curtain walls, fire doors, and both low- and high-temperature environments. It is especially ideal for workshops operating at temperatures above 50°C.

**Applications of Phenolic Insulation Board**
Phenolic foam has a thermal conductivity of about 0.023 (roughly half that of polystyrene, which is around 0.042). It is classified as non-combustible (Class A) and can withstand temperatures up to 150°C. Its cost is comparable to polyurethane, but unlike polystyrene or polyurethane, it does not burn easily and is resistant to high temperatures. This makes it an effective solution for fireproof insulation in buildings.
Phenolic insulation boards do not melt or soften, emit minimal smoke, and prevent flame spread. They offer excellent fire resistance and thermal insulation, making them ideal for exterior insulation. Common application forms include:
1. Double-sided aluminum foil (for wall insulation and decoration, and air conditioning ducts)
2. Single-sided color steel and aluminum foil (for air conditioning ducts)
3. Single-sided galvanized steel and aluminum foil (for air conditioning ducts)
4. Surface composites with other materials such as interface agents or mesh mortar (for fire-rated wall insulation)
5. Color steel sandwich panels, ideal for steel structure workshops, clean rooms, pharmaceutical facilities, and more. These panels combine two layers of pre-coated steel sheets with high-performance phenolic foam, offering energy efficiency, environmental friendliness, cost-effectiveness, and aesthetic appeal.
Customers can also choose additional materials like aluminum sheets or kraft paper based on their needs. Since the 1990s, phenolic foam has seen significant development. Initially valued by military sectors in the UK and US for aerospace and defense applications, it was later adopted in civil aviation, ships, oil rigs, and other high-risk fire environments. Over time, it has been increasingly used in high-rise buildings, hospitals, and sports facilities.
