As a supplier of white duplex board, I've often been asked about its fire - resistance. In this blog, I'll delve into this topic, providing you with in - depth information about the fire - resistant properties of white duplex board.
Understanding White Duplex Board
White duplex board is a type of paperboard that consists of two layers. The top layer is usually white, offering an excellent surface for printing, while the back layer can be grey or have other colors. It is widely used in various industries, such as packaging for clothing (like Shirt Single - sided Whiteboard Paper Printing Gray Background White Paper Cashmere Sweater Cardboard Round Neck Shirt T - shirt Whiteboard Paper Clothing Lining Paper White Duplex Board With Grey Back For Custom Printing Solutions), food, and consumer goods. The board is known for its stiffness, smoothness, and good printability.
Factors Affecting Fire - Resistance
The fire - resistance of white duplex board is influenced by several factors. Firstly, the raw materials used in its production play a crucial role. The pulp used can vary in its natural flammability. For example, if the pulp is sourced from softwood trees, it may have different burning characteristics compared to hardwood pulp.
Secondly, the manufacturing process can also impact fire - resistance. During the production of white duplex board, additives can be introduced to enhance its fire - retardant properties. These additives work by either releasing non - flammable gases when heated, forming a protective char layer on the surface of the board, or interfering with the chemical reactions that occur during combustion.
Measuring Fire - Resistance
There are several standard tests used to measure the fire - resistance of materials, including white duplex board. One of the most common tests is the ASTM D635 test, which measures the rate of burning of a plastic or paper material. In this test, a specimen of the white duplex board is held vertically and ignited at the bottom. The time it takes for the flame to reach a certain mark on the specimen is recorded, and the burning rate is calculated.
Another important test is the UL 94 test, which is used to classify the flammability of plastic and paper materials for use in electrical and electronic equipment. The UL 94 test has different ratings, such as V - 0, V - 1, and V - 2. A V - 0 rating indicates that the material stops burning within 10 seconds after two separate ignitions, and no flaming drips are allowed. A V - 1 rating means the material stops burning within 30 seconds after two ignitions, and no flaming drips are allowed. A V - 2 rating allows for flaming drips that can ignite cotton placed below the specimen.
Fire - Resistance of Standard White Duplex Board
Standard white duplex board, without any special fire - retardant treatments, is combustible. It will catch fire when exposed to an open flame and continue to burn until the fuel (the board itself) is consumed. The burning rate can vary depending on the thickness of the board, the type of pulp used, and the environmental conditions.
However, the good news is that we can enhance the fire - resistance of white duplex board. By adding fire - retardant chemicals during the manufacturing process, we can significantly improve its ability to resist burning. These treated boards can meet certain fire - safety standards, making them suitable for applications where fire - resistance is a concern.
Applications Requiring Fire - Resistant White Duplex Board
There are several industries where fire - resistant white duplex board is highly desirable. In the construction industry, it can be used for interior wall linings, false ceilings, and partition panels. In the transportation industry, it can be used for interior trim in vehicles, trains, and airplanes.
In the packaging industry, fire - resistant white duplex board can be used for packaging products that are sensitive to fire, such as electronic devices, batteries, and chemicals. For example, T - shirt, Shirt, Wrinkle Resistant, Folded Clothes, Whiteboard Paper, Customized Whiteboard Paper, Clothing Packaging, Cardboard Lining White Duplex Board With Grey Back can be made fire - resistant to provide an extra layer of safety for the clothing inside.
Our Fire - Resistant White Duplex Board Offerings
As a supplier, we offer a range of fire - resistant white duplex board products. Our Good Quality White Duplex Board Wtih Grey Back can be customized with different levels of fire - retardant treatments to meet your specific requirements. Whether you need a board that meets the V - 0 rating for high - risk applications or a board with a more moderate level of fire - resistance for general packaging, we can provide a solution.


Our fire - resistant white duplex board maintains the same high - quality printing surface and stiffness as our standard products. This means that you don't have to compromise on the appearance or functionality of your packaging or other applications.
Benefits of Using Fire - Resistant White Duplex Board
Using fire - resistant white duplex board offers several benefits. Firstly, it enhances safety. In applications where there is a risk of fire, such as in buildings or transportation, fire - resistant board can help prevent the spread of flames, giving people more time to evacuate and reducing the damage caused by fire.
Secondly, it can help meet regulatory requirements. Many industries have strict fire - safety regulations that must be followed. By using fire - resistant white duplex board, you can ensure that your products or applications comply with these regulations.
Finally, it can improve the overall quality and durability of your products. Fire - retardant treatments can also have a positive impact on other properties of the board, such as its resistance to moisture and pests.
