With the increasingly strict fire rating requirements of thermal insulation sandwich panels, PUR faces huge challenges in meeting fire protection regulations. The use of thermal insulation sandwich panels with higher fire safety performance is one of the primary considerations for various buildings and large-scale cold storage projects. One, and the emergence of PIR (polyisocyanurate) just solved this problem, PIR - excellent low temperature cold insulation material! It is an improved polyurethane material. Compared with PUR (ordinary polyurethane material), it has the following advantages:

■High fire safety performance: PIR core material is B1 grade refractory fuel, self-extinguishing away from fire, will not melt when burning, and low smoke content, no high temperature decomposition droplets.

■ Wide range of operating temperature: The operating temperature of the core material is between -180℃~+120℃. even at low temperature

It has small shrinkage and no embrittlement when used in an ultra-low temperature environment, and is an ideal thermal insulation material for large-scale cold storage projects;

■Good thermal insulation effect: the thermal conductivity is lower than 0.021, and the thermal insulation performance is good. can be reduced due to internal

The heat transfer generated by the external temperature difference can achieve the maximum efficiency of the freezing and refrigeration system;

High efficiency and environmental protection: The core material is made of six-component material, which is non-toxic and tasteless when burned, and the gas that escapes

It is harmless to the human environment and meets the national environmental protection requirements. It is a new type of green energy-saving and environmentally friendly building materials;

The impact resistance is better than EPS and other thermal insulation materials: PIR is a material with a high strength ratio (material strength to bulk density ratio). Also stronger. It can withstand the collision of normal human body and handling items, and will not cause damage to the external thermal insulation system when it is subjected to general collision.

Waterproof and moisture-proof: PIR core material is an organic polymer foam material, and its structure is closed-cell type.

Water rate ≤ 3%, with excellent water resistance and resistance to water vapor permeability, no moth-eaten, no weathering;

■Cost saving: The mechanical patch panel is easy to install, the construction speed is fast, and the efficiency is high. Save construction costs.

The automatic continuous line put into production by Yanghu Company is mainly used to produce fireproof polyurethane sheet (PIR). At the same time, after the expansion, it can also produce fireproof and thermal insulation sandwich panels for steel structures. The thickness and width of the core material can be customized according to customer requirements. The maximum width is 1125mm, and the length can be customized. The products are mainly used for external insulation of building exterior walls, large-scale cold storage projects, central air-conditioning air supply pipes, steel structure wall panels and roof panels, etc.

For our Yanghu company, the PIR we produce has the following advantages:

■Superior physical properties of the product: high closed cell rate, low water absorption, flame retardant, high compressive strength and so on.

■Short production cycle: continuous production line, large output, the maximum daily output can reach 3000 square meters.

■High cutting precision: the error range can be controlled to 0.3mm. It can be cut into any size of plate.

■Free customization: The outer panel can be customized with different materials and thicknesses according to the needs; the core material can be customized B1 and B2;

■Multiple mold sizes: It can produce insulation sandwich panels with different thicknesses between 40mm-200mm;

■Beautiful appearance: smooth and tough steel, reasonable structure, smooth without bubbles;
