PUR Hot Melt Adhesive Reactive Polyurethane Glue Strong Bonding Anti Yellowing 40min Open Time for Mattress Lamination

1. Strong Bonding and Durable Performance

• High adhesion strength: Exhibits excellent adhesion to various mattress materials such as sponge, latex, memory foam, and fabric. The final bond strength is high, ensuring long-term structural stability of the mattress.

• Excellent weather resistance: After curing, it forms an irreversible, strong adhesive layer with outstanding resistance to heat, moisture, and chemicals. It withstands high-temperature and humid environments, effectively extending the service life of the mattress.

2. Superior Production Efficiency

• High initial tack and fast curing: Quickly establishes initial strength after application, significantly reducing pressing and waiting time. It supports high-speed continuous operation on automated production lines, greatly improving overall manufacturing efficiency.

• Reduced adhesive consumption: Compared to traditional water-based adhesives, it requires less adhesive per unit area, thereby lowering production costs.

3. Environmental Friendliness and Health Safety

• Solvent-free, low VOC: Contains no organic solvents, with extremely low odor and minimal VOC (Volatile Organic Compounds) emissions. This improves the workshop working environment and provides consumers with a healthier sleeping experience.

• Safe and non-toxic: Made from environmentally friendly materials, it is non-toxic and odorless. Some products also feature anti-mildew properties.

4. Excellent Appearance and Surface Quality

• Anti-yellowing properties: The formulation is optimized to effectively resist yellowing caused by thermal oxidation and UV exposure, ensuring that light-colored fabrics and foam materials maintain their original color after lamination.

• Smooth adhesive layer: After curing, the adhesive layer is extremely thin and smooth. Unlike water-based adhesives, it does not cause material swelling or uneven surfaces, making it particularly suitable for products with high surface quality requirements.

5. Excellent Process Adaptability

• Wide range of applicable materials: Reliably bonds various commonly used mattress materials and is compatible with both manual and automated production lines.

• Flexible operating window: Offers an appropriate open time for easy process control. After curing, the adhesive layer maintains permanent elasticity and flexibility, capable of absorbing dimensional changes caused by temperature variations between different materials, thus preventing delamination.
