Ingredients Introduction

Core Raw Materials

Isocyanates: mainly include toluene diisocyanate (TDI), diphenylmethane diisocyanate (MDI), etc., which are key components for forming polyurethane structures.

Polyols: such as polyether polyols or polyester polyols, react with isocyanates to form the main chain structure of polyurethane, which determines the elasticity and temperature resistance of the material.

Auxiliary additives: including flame retardants (to improve fire resistance), plasticizers (to enhance flexibility), foaming agents (for foam structure molding), antioxidants (to extend life), etc., used to optimize material properties.

Chemical Properties

PU boards form urethane bonds through the polymerization reaction of isocyanates and polyols, and have a highly adjustable molecular structure. Different densities, hardness and functional properties can be obtained through formula adjustment.

Performance characteristics

Insulation and energy saving

The thermal conductivity is as low as 0.058 W/(m·K), which is much better than traditional materials (such as polystyrene), and is suitable for building insulation and cold chain equipment.

The sandwich structure design can reduce the thickness of the building's exterior enclosure and improve the utilization rate of indoor space.

Mechanical properties

The tensile strength can reach 265 MPa, the wear resistance is 3-5 times that of rubber, and the tear resistance is excellent.

The longitudinal shear characteristic value reaches 38 N/mm, and the transverse tensile characteristic value reaches 51 N/mm, which meets the needs of high-load scenarios.

Weather resistance and stability

Chemical corrosion resistance (acid and alkali resistance, oil pollution resistance), adaptable to industrial environment.

The closed-cell structure is waterproof and moisture-proof, with an average deformation of only 0.24 mm(720 hours test), and strong long-term stability.

Safe and environmentally friendly

The flame retardant grade can reach B1 (difficult to burn), and a carbonized layer is formed on the surface during combustion to delay the fire.

It does not contain harmful substances such as formaldehyde and meets green building standards.

Product selling point

High efficiency and energy saving

As the insulation layer of building exterior walls or cold storage, it can reduce energy consumption by 30%-50%, which is in line with the national energy-saving policy orientation.

Lightweight and convenient

Density range 40-60 kg/m³, the weight is only 1/10 of concrete, and the transportation and installation costs are low.

Supports a variety of processing methods such as cutting, folding, and on-site spraying, adapting to complex structural requirements.

Economical

The overall cost is low. Although the unit price is slightly higher, the long-term energy-saving effect is significant, and the life span can reach more than 3 times that of traditional materials.

Application fields

Construction industry

Roof panels and walls: used in steel structure factories, gymnasiums, etc., with both insulation and decoration functions.

Cold storage and cold chain: as cold storage sandwich panels, maintain a constant low temperature environment and reduce food loss.

Transportation

Automotive parts: interior panels, sound insulation layers, seat fillings, with both shock absorption and lightweight requirements.

Shipping and aviation: used for insulated bulkheads and floating fenders, with excellent weather resistance.

Industry and people's livelihood

Furniture manufacturing: imitation wood furniture, cabinet panels, with customizable textures and colors on the surface.

Packaging and sports equipment: protective foam packaging, ski core materials, etc., using their high elasticity and wear resistance.

Special scenarios

Purification engineering: hospital operating rooms, electronic workshop interior walls, easy to clean and dust-free.

Agriculture and energy: greenhouse insulation, solar equipment insulation layer
