Manufacturer of phenolic exterior wall panels
Excellent fire resistance
phenolic exterior wall panels is used as the thermal insulation layer, which is compounded with other materials for building thermal insulation. It can basically reach the national fire protection standard Class A, fundamentally eliminating the possibility of external insulation fire. The temperature range is-60 ℃~+150 ℃.
Outstanding energy-saving effect of phenolic insulation
Phenolic insulation board has good thermal insulation performance, its thermal conductivity is about 0.022W/(m · k), which is far lower than the inorganic and organic external wall insulation products commonly used in the market at present, and can achieve higher energy saving effect.
’Phenolic is widely used
It can not only be used in the traditional external wall thermal insulation system, but also can be combined with the finishing layer to make an integrated thermal insulation and decoration board. It can also be used to build the traditional EPS/XPS/PU external wall thermal insulation system fire isolation belt, which can be used as the fire insulation and thermal insulation materials in curtain walls, fire doors, and fire insulation and thermal insulation materials in low-temperature or high-temperature occasions.
Phenolic insulation board is made of phenolic foam, which is mainly composed of phenol and formaldehyde. Phenolic foam is a new type of fire-resistant, fireproof and low smoke insulation material (under limited conditions). It is a closed cell rigid foam plastic made of phenolic resin added with foaming agent, curing agent and other additives.
The thermal conductivity of phenolic foam is about 0.023 (about 1/2 of polystyrene, and the thermal conductivity of polystyrene board is about 0.042), the fire rating is incombustible B (can withstand 150 ℃ high temperature), and the price is similar to that of polyurethane. Polystyrene foam and polyurethane foam are both flammable and not resistant to high temperature. Their use is restricted by the fire department. Phenolic fire-proof insulation board can effectively solve the problem of building fire protection and insulation. Phenolic insulation board does not melt, soften, emit low smoke, does not spread flame, is resistant to flame penetration, has excellent fire protection performance, and has good heat preservation and energy conservation effect. It combines excellent fire prevention performance with good energy conservation effect, and is suitable for external wall insulation. Application form of phenolic insulation board:
1) External thermal insulation of building exterior wall (thin plastering system, integration of thermal insulation and decoration, curtain wall system)
2) Central air conditioning composite duct insulation (steel faced phenolic composite duct, double-sided aluminum foil phenolic composite duct)
3) Color steel sandwich panel field (movable panel room, purification project, clean workshop, cold storage, cabinet room, etc.)
4) Roof thermal insulation (residential roof, factory roof, roof thermal insulation brick)
5) Low temperature cryogenic pipeline insulation (LNG pipeline, LNG pipeline, cold and hot water pipeline)
6) Other fields requiring thermal insulation
Since the 1990s, phenolic foam materials have been greatly developed. First, they were valued by the British and American military and used in aerospace, defense and military industries. Later, they were used in places with strict fire protection requirements such as civil aircraft, ships, stations, oil wells, and gradually pushed to high-rise buildings, hospitals, sports facilities and other fields.
