product details

PIR is a foaming material with a cross-linked structure formed by using different ratios of isocyanate and polyol and adding different catalysts and additives on the basis of polyurethane foam. It contains more isocyanate groups in its chemical structure. PIR foam is flame retardant, has low thermal conductivity, is lightweight, has high bending strength, does not absorb water, and does not rot.

Product Advantages

1.Superior Fire Performance

PIR foam core achieves high fire resistance ratings, slows flame spread, and releases less smoke and toxic gases during combustion.

2.Excellent Thermal Insulation

PIR foam provides outstanding thermal efficiency with low thermal conductivity, significantly reducing building energy consumption year-round.

3.Lightweight & High Strength

The rigid PIR core bonded with metal facings creates a strong yet lightweight panel, reducing structural load and simplifying installation.

4.Moisture & Chemical Resistance

PIR foam resists moisture absorption and chemical attack, preventing core degradation and ensuring long-term durability in harsh environments.

Manufacturing Process of PIR Sandwich Panels

Using the drum principle, the metal plate is placed on a specially designed conveyor plate, and the spraying device sprays the PIR foaming agent on the metal sheet. After high-temperature treatment, the foaming agent is formed between the metal sheets. We can produce different types and grades of PIR panels according to customer needs. The sandwich panel production line adopts a continuous foaming process, which can complete the batching at one time, and can adjust the proportion online at will according to the temperature, so as to produce high-standard building panels.
