PVC furniture edge banding

PVC furniture edge banding is an important decorative and protective material widely used in the furniture manufacturing industry. It is mainly made of polyvinyl chloride (PVC) as the basic raw material, and is made by adding various functional additives through extrusion molding process.

1. Composition of raw materials

Polyvinyl chloride (PVC): As the main material, it endows the edge banding with basic toughness, plasticity, and chemical resistance. PVC resins with different degrees of polymerization can cause differences in the hardness, flexibility, and other properties of the edge banding. For example, PVC with higher polymerization degree can enhance the strength and wear resistance of edge banding.

Plasticizers: To improve the flexibility and processing performance of PVC, plasticizers such as phthalates are often added. The amount of plasticizer used determines the softness of the edge banding. When used in large quantities, the edge banding becomes softer and is suitable for furniture parts that require bending and attachment.

Stabilizers: Due to factors such as heat and light, PVC is prone to decomposition during processing and use. Adding stabilizers (such as lead salts and organotin compounds) can improve its thermal stability and weather resistance, prevent edge banding discoloration, aging, and performance degradation.

Lubricant: In order to reduce friction between PVC and equipment during processing, improve melt flowability, and make molding smoother, lubricants such as stearic acid are added to ensure a smooth surface of the edge banding strip without defects such as flow marks and bubbles.

Coloring agent: To meet the diverse color needs of furniture, organic or inorganic pigments are added as coloring agents to give the edge banding rich colors, such as common wood like colors, white, black, etc., making it perfect for matching with furniture boards.

2. Characteristics

Highly decorative: Through advanced printing and embossing techniques, various textures and textures of materials can be imitated, such as wood grain, stone grain, leather grain, etc., which can realistically simulate the appearance of solid wood furniture and enhance the overall beauty and grade of the furniture.

• Good flexibility: PVC material itself has a certain degree of elasticity, and the edge banding can be easily bent to adapt to various shapes of furniture edges. Whether it is straight or curved edges, they can be tightly fitted, achieving seamless connection and enhancing the overall sense of furniture.

Excellent wear resistance: In daily use, furniture edges are prone to friction and scratching. The surface of PVC edge banding has been specially treated to have high hardness and wear resistance, which can effectively protect the edges of furniture boards and extend the service life of furniture.

Good chemical resistance: It has a certain tolerance to common acids, bases, oils, and other chemicals, is not easily corroded, and can maintain the integrity and aesthetics of furniture edges. It is particularly suitable for furniture environments such as kitchens and bathrooms that are prone to chemical substances.

Waterproof and moisture-proof: PVC is a material with good waterproof performance. The edge banding can effectively prevent moisture from entering the interior of furniture boards, prevent the boards from deforming and moldy due to moisture, and improve the structural stability and durability of furniture.

3. Specifications and dimensions

• Thickness: The common thickness range is between 0.3-3mm. Thinner edge banding strips (0.3-0.6mm) are commonly used for furniture with high appearance requirements and a pursuit of lightweight effects, such as laminated edge banding for customized wardrobes; Thicker edge banding (1-3mm) pays more attention to protection and texture, and is commonly used on the edges of furniture that is prone to wear and tear, such as dining tables and desks.

Width: Generally 12-120mm, the specific width depends on the thickness of the furniture board and design requirements. For example, conventional 18mm thick boards are often paired with 18-25mm wide edge banding to ensure complete coverage of the board edges.

4. Application scenarios

Panel furniture: It is the main application area of PVC edge banding, such as wardrobes, cabinets, bookshelves, office desks, etc. By edge sealing treatment, not only can the appearance of furniture be beautified, but it can also prevent the release of harmful substances such as formaldehyde inside the board, improving the environmental performance of furniture.

Solid wood furniture: In solid wood furniture, PVC edge banding is also used for some splicing parts or edges that require additional protection. It can cover the splicing gaps and enhance the wear resistance of the edges, making solid wood furniture more perfect.

Office furniture: such as desks, chairs, filing cabinets, etc., PVC edge banding can provide good decoration and protection, meeting the requirements of office environment for furniture durability and aesthetics.

5. Installation method

Hot melt adhesive bonding: This is the most common installation method. Use a hot melt adhesive machine to heat the hot melt adhesive to a molten state, apply it to the edge banding and furniture board edges, and then quickly attach the edge banding to the board, using the viscosity of the hot melt adhesive to make it firmly bonded. This method is easy to operate, highly efficient, and suitable for large-scale production.

• Back adhesive self-adhesive: Some PVC edge banding strips have been pre coated with adhesive on the back during the production process. When using, simply peel off the release paper and directly stick it to the edge of the furniture board. This method is easy to install and suitable for some small furniture factories or DIY furniture production.
