The characteristics of phenolic board

Phenolic board is a new type of non-combustible, fireproof and low-smoke insulation material made from phenolic insulation board. It is a rigid closed-cell foam made of phenolic resin, foaming agent, curing agent and other additives. Its main prominent features are non-flammability, low smoke and heat resistance. In addition, the present invention overcomes the shortcomings of the original foam plastic insulation material, such as flammability, smoking and thermal deformation, while maintaining the characteristics of the original foam plastic insulation material, such as light weight and convenient construction.

Product features of phenolic board

The excellent fire resistance performance of the building insulation composite materials such as phenolic foam in the insulation layer can basically meet the national safety fire protection design standard A-level, fundamentally eliminating the possibility of fire in the external insulation system. The applicable temperature range is between -250°C and 150°C.

2. The thermal insulation and energy-saving effect is outstanding. Phenolic thermal insulation has excellent thermal insulation performance, with a thermal conductivity of approximately 0.023w/(m·k), which is far lower than that of the inorganic and organic exterior wall insulation design technology products commonly used by Chinese enterprises in the current development of the Chinese economic market. It can simultaneously achieve a higher energy-saving management effect.

3. It has a wide range of applications and can be used in traditional external wall insulation systems. It can also be combined with decorative layers to make integrated insulation and decoration panels. Additionally, it can be used to build fire isolation belts in traditional external wall insulation systems. It can serve as a fireproof insulation material for curtain walls and fire doors, as well as in low-temperature or high-temperature environments.

Phenolic boards are classified as: Class A fireproof boards, fireproof research phenolic boards, foamed phenolic boards, exterior wall insulation boards, roof including phenolic insulation boards, resin-enhanced phenolic boards, composite control phenolic boards, modified and reinforced phenolic boards, and waterproof phenolic boards. The performance of phenolic board: high flame retardancy, low smoke emissions. The oxygen index can reach 56%, and the flue gas concentration is less than 5. It does not burn at 1200℃ and only carbonizes when it catches fire.

It has good insulation and low thermal conductivity. Phenolic foam is composed of "closed small bubbles", which can prevent the formation of thermal convection and phenomena between temperatures in China. In order to save energy. It has good weather resistance and high heat resistance. Phenolic insulation foam materials can be used within the temperature range of -60℃ to 150℃. They have stable dimensions, do not absorb water, are anti-aging, and have a long service life. Fluorine-free foaming, non-toxic and odorless, is a green building material.

During the foaming process, no chlorofluorocarbons are used. The proportioning is reasonable, and the reaction can be complete, forming a compound without residual toxins, odorless, acid and alkali resistant, and with good acid and alkali resistance. High flame retardancy, fluorine-free foam, green and environmentally friendly. Application scope: Polyphenolic thermosetting insulation boards and pipe shells are widely used in tunnel insulation, civil, industrial, petroleum, chemical, national defense and military, ship hulls, railway transportation insulation projects, cold storage, etc.

The application scope of the external wall phenolic insulation board system complies with the requirements of the Interim Provisions on Fire Protection for External Wall Insulation Systems of Civil buildings issued by the Ministry of Housing and the Ministry of Health. It is applicable to the energy-saving design and construction of new multi-story, medium and high-rise building enterprises as well as the energy-saving technological renovation of old buildings. Energy conservation in curtain wall and non-curtain wall buildings. Fire barrier. Exterior wall insulation decorative panels.
