In mattress manufacturing, latex layers are highly favored for their excellent elasticity, breathability, and comfort. However, ensuring a strong bond between the latex layer and other materials—while maintaining optimal breathability—requires an effective adhesive process. Among the available methods, the hot melt adhesive glue technique has gained wide adoption due to its efficiency, environmental friendliness, and strong bonding capability.
Fast Curing for Increased Production Efficiency
Hot melt adhesive, when heated to a molten state, can be evenly applied via spray and achieves bonding within a short period, significantly improving manufacturing efficiency.
Solvent-Free and Environmentally Safe
Unlike traditional solvent-based adhesives, hot melt adhesive contains no volatile organic compounds (VOCs), reducing harm to both workers and the environment. It complies with modern environmental standards and safety requirements.
Uniform Application Ensures Bonding Stability
The spray application allows precise control over adhesive distribution, forming an even adhesive layer on the latex surface and improving overall bonding performance.
Excellent Aging Resistance for Enhanced Durability
Hot melt adhesive demonstrates strong resistance to temperature and humidity, helping maintain the mattress's breathability and elasticity over time without delamination or degradation.
During mattress production, latex layers are typically bonded with materials such as foam, non-woven fabric, knitted fabric, or innerspring units. Hot melt adhesive glue is primarily used in the following processes:
Bonding Latex to Foam Layers
This ensures overall softness while enhancing the structural support of the mattress.
Bonding Latex to Non-Woven or Knitted Fabrics
It prevents material slippage, improving durability and comfort.
Fixing Latex in Multi-Layer Mattress Structures
The adhesive keeps the latex layer securely in place during long-term use, maintaining structural integrity and stability of the mattress.
Different types of hot melt adhesive are used to meet specific bonding needs for latex layers:
EVA-Based Hot Melt Adhesive
Offers good flow properties and moderate bonding strength, suitable for general-purpose latex mattress assembly.
Polyolefin (PO)-Based Hot Melt Adhesive
Provides excellent aging resistance and is ideal for mattresses that require long-lasting performance.
Polyurethane (PUR) Hot Melt Adhesive
Delivers outstanding resistance to heat and moisture, making it suitable for premium, high-end mattress applications.
Hot melt adhesive glue plays a critical role in latex mattress bonding, enhancing both production efficiency and bond reliability while aligning with environmental standards. By selecting the appropriate type of hot melt adhesive, manufacturers can optimize mattress performance, durability, and user comfort.
