Polyester wadding, also known as spray pulp wadding, is a type of non-woven fabric. The principle of forming the structure of polyester wadding is to spray adhesive on both sides of the fluffy fiber layer, and because there is a certain pressure when spraying, as well as the suction of the lower vacuum, the adhesive can also penetrate into the interior of the fiber layer. At the same time, in the three-dimensional mesh structure, there are still many air-holding voids. Therefore, the fiber layer has a porous, highly fluffy warmth.
Polyester wadding has excellent thermal insulation performance, which can effectively stop the heat conduction and reduce energy loss. It can form a continuous heat insulation layer on the walls, roofs and floors of buildings, etc., providing good heat insulation.
Polyester wadding has good sound insulation effect, which can reduce the transmission of noise. It can reduce the noise from indoor and outdoor, providing a quieter and more comfortable environment.
Polyester wadding can be applied to various irregular shapes and surfaces, such as the concave and convex surfaces of walls, pipes and beams. It can be easily sprayed on the surface that needs to be insulated, filling gaps and voids to form a continuous insulation layer.
Polyester wadding has excellent durability and is not susceptible to corrosion, decomposition or shrinkage. It can keep its insulation performance for a long time and does not need frequent replacement or maintenance.
Polyester wadding is usually made of fluorocarbon-free materials and will not pollute the environment. It also does not contain volatile organic compounds (VOCs), no negative impact on indoor air quality. Also, polyester wadding is not easy to breed mold and fungus, which helps maintain a healthy and clean indoor environment.
Polyester wadding is a pure polyester fiber, synthesized using a carding, spraying, and ironing process. It is sprayed in liquid form onto the surface to be insulated, then swells and cures to form a strong and continuous insulating layer. It is warm, tensile, resilient, moisture-resistant, and washable. It is fluffy and soft, flat and stiff. polyester wadding has the following application areas:
polyester wadding is widely used in the insulation of buildings. It can be sprayed onto walls, roofs, floors, and ceilings to fill gaps and cracks, effectively isolating indoor and outdoor temperature and sound. The excellent insulation performance of polyester wadding can significantly reduce energy consumption and indoor noise.
Polyester wadding can be used to insulate pipes, whether they are cold or hot water pipes. It can form a continuous protective layer on the surface of the pipes, preventing heat from dissipating or entering the piping system and improving energy efficiency. In addition, polyester wadding can also reduce the risk of freezing and cracking of water pipes.
Polyester wadding is also widely used in refrigerated equipment and vehicles. It can be sprayed on the interior surface of refrigerated warehouses, refrigerated vehicles and refrigerated containers to provide an effective insulation layer to prevent temperature changes and external environmental influences and maintain the freshness and quality of the goods.
Since polyester wadding has excellent insulation properties, it can also be used for sound isolation. Spray foam can reduce the transmission of sound waves and provide a quieter indoor environment. This is especially important in offices, conference rooms, recording studios, and other places in buildings where privacy and quiet are required.
The thickness of polyester wadding can vary depending on the specific application and needs, and there is no fixed standard thickness. Typically, the thickness of polyester wadding can be choosed based on the desired thermal performance, sound insulation and insulation requirements.
For insulation applications, polyester wadding thicknesses typically range from a few centimeters to several tens of centimeters, depending on the climatic conditions in the area, the type of building, and the level of insulation required.
For sound insulation applications, the thickness of polyester wadding can also vary. Thicker wadding provides better sound insulation, reducing the transmission and reflection of sound.
Similarly, for insulation applications, the thickness of polyester wadding will vary depending on the insulation required. Thicker wadding provides better insulation and stops the transfer of heat.
Therefore, there is no fixed value for the thickness of polyester wadding, but rather it needs to be determined based on the specific needs and application. When selecting polyester wadding, it is recommended to consult a professional supplier or consulting engineer for more accurate advice and guidance.
Polyester wadding generally has minimal shrinkage. Polyester is a synthetic fiber that is known for its excellent dimensional stability and resistance to shrinkage. Unlike natural fibers such as cotton, polyester fibers have a limited ability to shrink when subjected to heat or moisture.
However, it is important to note that the shrinkage of polyester wadding can vary depending on several factors such as the specific manufacturing process, the quality of the polyester fabrics, and the care instructions followed during washing and drying.
To minimize the risk of shrinkage, it is recommended to follow the care instructions provided by the manufacturer. Typically, polyester wadding can be safely machine washed and dried without significant shrinkage. However, it is advisable to use a gentle cycle and low heat settings when washing and drying polyester wadding to maintain its original shape and size.
If you have specific concerns about shrinkage, it is always best to consult the product label or contact us(G&F GROUP INC.) for precise information regarding the shrinkage characteristics of the particular polyester wadding you are using.
Since polyester wadding is added to the adhesive under spraying condition, not under impregnation condition, and it is no longer cured and molded by the pressure of extrusion after spraying. Therefore, in the bonded state of the fibers, the cross point contact is predominant, and the lumping by the adhesive bridging is less, which is the main reason why polyester wadding can remain loose, soft, and warm.
Polyester wadding itself does not pose a direct hazard to humans. It is a common insulating material and is usually made from non-toxic, non-hazardous ingredients such as polyester, glass fiber or mineral fiber.
However, there are a number of potential health risks that can arise when using polyester wadding, and the following are precautions to take:
1. Dust and fibers: During the installation of polyester wadding, a certain amount of fine dust and fibers will be generated. If a large amount of dust and fibers are inhaled, it may cause respiratory irritation and discomfort. Therefore, when installing polyester wadding, it is recommended to wear appropriate respiratory protective equipment such as masks and goggles.
2. Volatile Organic Compounds (VOCs): Some polyester wadding products may contain volatile organic compounds. These compounds may emit odors during the initial release phase of the material. Prolonged exposure to high concentrations of VOCs may cause certain effects on human health. When choosing polyester wadding products, you can choose products that meet environmental standards and low volatility, and make sure the room is well-ventilated.
3. Allergic reactions: Individuals may have allergic reactions to fiber materials, including polyester and glass fibers and other polyester wadding component materials. If allergy symptoms or sensitivities exist, exposure to these materials may cause skin irritation or respiratory discomfort. When installing or handling polyester wadding, personal protection should be observed to avoid direct contact.
