Product Introduction
What is PU sandwich panel?
PU sandwich panel (polyurethane sandwich panel) is a new type of energy-saving board made by compounding double-sided color-coated steel plates or other panel materials as surface materials and polyurethane rigid foam as core materials through special production equipment. It adopts a continuous foaming composite process, which enables the surface material and core material to be closely combined, forming an integrated board with multiple properties such as thermal insulation, load-bearing and compressive resistance, fire resistance and moisture resistance. It is an ideal material to replace traditional bricks, stones and color steel tiles in the modern construction field.
Core Advantage
Why choose our PU sandwich panels?
Ultimate heat preservation, energy conservation and consumption reduction
The core material adopts high-density polyurethane rigid foam, with a closed-cell rate of over 95% and a thermal conductivity of only 0.024-0.028W/(m·K), which is far superior to traditional insulation materials such as rock wool (0.036W/(m·K)) and glass wool. Buildings constructed with this type of board can reduce heating energy consumption by 30% to 50% in winter and cooling energy consumption by 25% to 40% in summer. Long-term use can significantly save operating costs.
Safety and fire protection compliance certification
It is strictly produced in accordance with the GB8624-2012 standard, with a fire resistance rating up to B1 (difficult to ignite). When exposed to fire, it only carbonizes slowly without generating molten droplets or releasing any toxic or harmful gases. The core material is added with special flame retardants, which slow down the flame spread speed and can effectively delay the spread of fire, buying precious time for personnel evacuation and fire rescue. It has been certified by the National Fire Product Quality Supervision and Inspection Center.
High-strength wind and pressure resistance
The surface material is made of high-quality color-coated steel plate, with a thickness that can be selected from 0.3 to 0.8mm. The core material density is ≥40kg/m³. After composite, the bending strength of the plate is ≥15MPa, and the compressive strength is ≥30MPa. It can be directly used as a load-bearing structure for roofs and walls, capable of withstanding severe weather conditions such as typhoons of level 12 and heavy snow. It maintains stable performance in extreme environments ranging from -40℃ to 80℃, with a service life of up to 15 to 20 years.
Convenient installation saves time and effort
It adopts a tongue-and-groove splicing design, requiring no complex base treatment. The weight of a single board is only 1/10 of that of a traditional brick wall, and the installation work can be completed by 2 to 3 people. The length of the panels can be customized according to project requirements (up to 6 meters), reducing the seams at the joints. The installation efficiency is over 60% higher than that of traditional panels. The installation of a 1,000 square meter factory wall can be completed in just 3 to 5 days, significantly shortening the construction period.
More advantages, comprehensive protection
Moisture-proof and waterproof
The surface material undergoes multiple processes such as pre-coating and curing, offering excellent waterproof performance. The core material does not absorb water and will not mold or deteriorate even in a humid environment, making it suitable for rainy areas in the south and scenarios like cold storage and basements.
Sound insulation and noise reduction
The polyurethane rigid foam core material has excellent sound insulation performance. The air sound insulation of a 100mm thick board is ≥40dB, effectively blocking external noise and providing a quiet environment for workshops, offices, etc.
Aesthetically pleasing and durable
The surface material color can be customized, with a smooth and flat surface that requires no secondary decoration. The coating is made of fluorocarbon or polyester paint, which is UV-resistant, anti-aging and does not fade easily after long-term use.
Environmental protection and health
The production process does not release any harmful gases such as formaldehyde. The core material can be recycled and reused, meeting national environmental protection standards and having been awarded the "Green Building Preferred Product" certification.
