How long is the service life of polyurethane hard foam insulation composite board

Under normal use and maintenance conditions, the average lifespan of polyurethane hard foam insulation composite panels can reach more than 30 years, and some high-quality products can even reach 50 years. This conclusion is based on the following key factors:

1. Material characteristics and durability

Closed-cell structure: The porosity structure of polyurethane hard bubbles is stable, basically a closed-cell structure. This structure not only has excellent thermal insulation performance, but also has good freeze-thaw resistance and sound absorption. High closed cell rate can prevent air from flowing between the cells, reduce convection heat transfer, thereby improving thermal insulation performance and extending the service life of the material.

Strong resistance to deformation: Polyurethane hard bubbles are not easy to crack, the finish is stable and safe, and can adapt to normal deformation of building structures without cracks, hollowing and other phenomena.

Weather resistance and chemical stability: Polyurethane hard bubbles can be used for a long time in an environment of -50℃ to 150℃, and the short-term use temperature can even reach 250℃ without any damage. Its physical and chemical properties are very stable, insoluble in most solvents, not affected by waste gas and industrial gases, are not rotten, anti-plastic, anti-corrosion, odorless, and non-toxic.

2. Environmental adaptability

Moisture-proof and waterproof: The closed cell ratio of polyurethane hard bubbles is above 90%, which is a hydrophobic material. It will not increase the thermal conductivity due to moisture absorption, and there will be no water seepage on the wall. This characteristic allows it to maintain stable thermal insulation performance in humid environments.

Resistance to corrosion and biological damage: Polyurethane hard bubble insulation composite panels will not be damaged under the influence of dryness, humidity or electrochemical corrosion, as well as external factors such as insects, fungi or algae growth or rodent damage.

3. Fire resistance and safety

Fire-retardant flame retardant: After adding flame retardant, polyurethane is a flame-retardant self-extinguishing material, and its softening point can reach more than 250 degrees Celsius. Carbon deposits will form on the foam surface during combustion, effectively preventing the flame from spreading, and almost no toxic carbon monoxide gases are produced during combustion.

Low smoke volume: Polyurethane hard foam will not melt, have no drips when burning, and the smoke volume will be low, which will improve the safety of the building.

4. Factors for extending service life

Production by regular manufacturers: The raw material quality, production process, etc. can be guaranteed by complying with the specifications, thereby extending the service life.

Regular maintenance and maintenance: Regular inspection, maintenance and maintenance of polyurethane insulation materials, timely discover and deal with problems, which can effectively extend their service life.
