I. Core Performance of PU Insulation Panel
Super strong heat insulation and heat preservation performance
With polyurethane (PU) as the core material, its thermal conductivity is as low as ≤0.022W/(m · K), which is far superior to traditional materials such as rock wool (≥0.040W/(m · K)) and EPS (≥0.033W/(m · K)).
The core material has a closed-cell rate of over 95%, effectively blocking air convection and heat conduction. It maintains stable insulation performance in an environment ranging from -40 ℃ to 80℃, making it suitable for extreme scenarios such as low-temperature cold storage and high-temperature workshops.
Reliable fire resistance performance
The core material is added with environmentally friendly flame retardants and has passed the B1 grade test of GB 8624-2012 "Classification for Fire Performance of Building Materials and Products". When exposed to fire, it only carbonizes on the surface without generating molten droplets.
The smoke toxicity grade reaches "ZA1" (the lowest toxicity), meeting the fire protection requirements of industrial plants, public buildings, etc.
Anti-aging and structural strength
The surface coating can be selected from color steel plate, aluminum foil, glass fiber cloth, etc. It is resistant to acid and alkali, ultraviolet aging, and can resist rain erosion and temperature difference deformation when used outdoors.
The composite structure design enables the sheet to have a bending strength of ≥15MPa and a compressive strength of ≥20MPa, allowing it to be directly used as a sheet for the enclosure structure and reducing the need for additional supporting components.
II. Application Fields of PU Insulation Panel
The construction industry
It is used for the exterior walls/roofs of industrial plants, individual household insulation in residential buildings, and the enclosure of cold chain logistics cold storage. For instance, if PU insulation boards and color steel cladding are adopted for food cold storage, the cold loss rate can be reduced by 30%, and about 15% of electricity bills can be saved each month.
The field of transportation
As the core insulation material for refrigerated trucks and insulated containers, its weight is only one-third of that of traditional insulation materials, which can reduce vehicle energy consumption while ensuring structural stability under bumpy road conditions.
The field of electronics and equipment
It is used for constant temperature boxes of precision instruments and insulation covers of photovoltaic inverters. With low thermal conductivity and resistance to humidity changes, it ensures the operational accuracy of the equipment in harsh environments.
