Advanced moisture-curing PU formula forms irreversible chemical bonds, creating a dense polymer network upon reaction with ambient humidity. It delivers an exceptional ≥8N/25mm peel strength for fabrics, leather, and non-wovens, ensuring firm, non-delaminating adhesion even under severe external forces. Beyond standard textiles, this reactive cross-linking technology provides multi-substrate versatility, enabling high-strength bonding across plastics, metal films, and specialized coated materials without compromising structural integrity.
FLEX Machinery Co., Ltd. not only supplies customers with high-quality and cost-effective PUR hot melt adhesive machine lines, but also offers comprehensive formula technical support. This includes customized solutions such as wood-bonding flat lamination, wood edge sealing, wood wrapping adhesives, and specialized formulations for textile adhesives. To eliminate compliance barriers during international tenders or export reviews, we provide exhaustive technical documentation, including detailed TDS (Technical Data Sheets), MSDS (Material Safety Data Sheets), and verified third-party testing reports.
Engineered for extreme environments, the cured adhesive withstands 50+ cycles of 40–60℃ machine washing without degrading. It performs stably across a demanding -30℃ to 120℃ range, keeping bonded textiles completely intact. This reliable thermal and chemical resistance prevents deformation, discoloration, or adhesion loss, providing an exceptional moisture barrier and enduring harsh weather conditions effortlessly.
Formulated with sustainability in mind, this adhesive guarantees zero harmful VOC emissions (VOCs <5g/L). It strictly meets the OEKO-TEX® Standard 100 Class I criteria, making it entirely safe for direct skin contact in intimate apparel, baby clothes, and medical textiles. By adopting this low-carbon, eco-friendly formulation, procurement teams can actively advance their ESG compliance targets and promote green manufacturing initiatives.
The 100% solid content formula preserves the textiles’ original soft handfeel without any unwanted stiffening or hardening at the bond line. It achieves initial tack in just 10 seconds, drastically boosting production efficiency. Designed for seamless production line compatibility, it perfectly adapts to automated rolling, spraying, and dot coating equipment, accelerating manufacturing tempos and reducing manual intervention.
The water-free and solvent-free solid state eliminates evaporation waste, significantly lowering the per-unit coating cost while saving on logistics and warehousing expenses. Furthermore, it robustly resists UV exposure, oxidation, and hydrolysis. By maintaining stable performance for over 5 years, it substantially lowers after-sales risks and enhances the long-term market competitiveness of the final manufactured goods.
Understanding the precise technical specifications of our PUR Hot Melt Adhesive is crucial for optimizing your manufacturing workflow. The parameters detailed below highlight the formulation's physical characteristics, from its white solid block appearance to its specific application temperatures. Operating strictly within the 110℃-130℃ range ensures optimal viscosity, allowing the adhesive to penetrate fabric fibers deeply while retaining the substrate’s inherent soft handfeel. Review these exact specifications to calibrate your automated coating machinery accurately.

Ideal for bonding waterproof fabrics, fleece linings, and elastic bands. Its wash resistance and temperature adaptability ensure absolute zero delamination after repeated use and heavy cleaning. The adhesive maintains the breathable, flexible nature of athletic gear, perfectly matching the rigorous durability demands of outdoor and active sports apparel exposed to the elements.
Suitable for laminating heavy curtains, sophisticated sofa covers, and premium bed linens. It effortlessly retains the fabrics’ natural softness and drape without stiffening the material. Furthermore, its excellent aging resistance prevents bonding failure caused by long-term sunlight exposure or frequent household washing.
Strictly complies with OEKO-TEX® Standard 100 Class I, making it entirely safe for sensitive applications like underwear, baby rompers, and bibs. It bonds delicate fabrics gently without leaving any chemical residue or odor that might irritate the skin, while maintaining maximum flexibility for comfortable, all-day wearing.
Perfect for manufacturing disposable surgical gowns, sterile wound dressings, and medical bed sheets. Its solvent-free formula completely avoids harmful VOC emissions, ensuring a clean production environment. Its strong adhesion withstands rigorous sterilization processes to ensure reliable, fail-safe performance in critical healthcare settings.
Power on the equipment and set the heating temperature strictly to 120–140℃ (follow adhesive technical specs). Wait 15 mins for temperature stabilization; visually confirm the melt is smooth and listen to ensure no abnormal noise or leakage from the system. Carefully check the fabric material and clean the coating roller to avoid any micro-impurities that might affect the final bonding effect.
Load the solid PUR adhesive sticks into the hopper; ensure continuous and smooth feeding without overloading. Select the precise application mode (rolling/spraying/dot coating) based on the specific textile type and desired breathability. Adjust the coating speed precisely to 3–5m/min to guarantee a uniform, consistent adhesive film thickness (0.1–0.2mm recommended).
Laminate the fabrics immediately after coating while the adhesive is active, and apply an exact 0.2–0.3MPa of mechanical pressure for 10–20s. Place the newly bonded textiles in a well-ventilated staging area (20–25℃, 50–60% ambient humidity) for a full 24h curing cycle. Strictly avoid any water washing or high-temperature ironing during this critical cross-linking period.
Turn off the power and thoroughly clean any residual adhesive in the hopper or roller using a professional cleaning agent to prevent blockages. Store all unused adhesive in a sealed, dry environment to prevent premature moisture absorption. For any operational troubleshooting, refer directly to the equipment manual or contact our dedicated technical support team.
A: FLEX Machinery Co., Ltd. not only supplies customers with highly efficient and cost-effective machines, but also offers a comprehensive range of services tailored to specific manufacturing needs. This includes specialized adhesive formula technical support (complete with TDS and MSDS documentation), full-process production guidance, as well as dedicated overseas machine installation and commissioning services to ensure your production line runs smoothly.
A: For optimal cross-linking and maximum peel strength, cure the bonded materials at 20–25℃ with 50–60% ambient humidity for exactly 24h. Ensure the storage area has good ventilation; strictly avoid any water contact or exposure to high temperatures during this period to lock in a stable, irreversible bonding effect.
A: It works exceptionally well with most standard fabrics like cotton, polyester, genuine leather, and non-wovens, forming a dense polymer network upon curing. For special coated textiles, plastics, or metal films, we highly recommend testing compatibility with a small sample to verify peel strength before proceeding with mass application.
A: Store the solid blocks in a completely sealed, dry, and cool place below 25℃, keeping them safely away from moisture and direct sunlight. Any unsealed adhesive must be used up within 48h to prevent premature moisture absorption, which could lead to unwanted curing failure within the hopper.
A: No. Its advanced, flexible formula specifically maintains the original soft handfeel and natural drape of the fabrics after full curing. It achieves this without causing any stiffness, hardening, or crustiness at the bonded areas, ensuring premium tactile quality for the end user.
