Product Advantage
Our elastic attachment adhesive offers industry-leading creep resistance. It firmly anchors elastic strands to nonwovens, maintaining high elasticity retention even when the diaper is stretched or under body heat, effectively preventing leg cuff leakage.
Formulated with advanced styrene block copolymers (SBC), this hot melt glue creates a robust yet flexible bond interface. It delivers high initial tack (green strength) and excellent long-term shear strength, ensuring structural integrity during dynamic movement.
The adhesive exhibits a stable viscosity profile and excellent thermal resistance, preventing charring or gel formation in the tank. It is highly compatible with standard high-speed production lines, ensuring clean and precise spray patterns (spiral spray, omega spray, or meltblown) without nozzle buildup.
Engineered with ultra-pure raw materials, this non-fluorescent elastic hot melt is completely odorless and non-toxic. It complies strictly with REACH and RoHS standards, protecting infants' and adults' sensitive skin from irritation.
Diaper leg cuffs undergo continuous stretching and contraction during infant movement. This elastic attachment glue is formulated to deliver outstanding shear stability under dynamic tension, maintaining an ultra-low creep rate over extended periods and ensuring the elastic gather never slips or fails.
Engineered with controlled rheological properties, this hot melt adhesive achieves precise positioning without penetrating or bleeding through thin nonwoven substrates. It prevents machine buildup and contamination while preserving the original fabric softness and breathable texture for ultimate comfort.

Product Uses
Baby Diapers & Pull-up Training Pants
The most critical application is bonding the leg elastics (leg cuffs) and elastic waistbands of baby diapers. It ensures the elastics are evenly gathered to provide a snug fit, preventing leaks while keeping the baby comfortable.
Adult Incontinence Briefs & Underwear
Used for manufacturing adult protective underwear and heavy-duty incontinence products. It handles the higher tension and larger elastic strands required for adult sizing, maintaining excellent bond reliability.
Elastic Ear & Waistband Attachments
Ideal for bonding elastic ears, stretch panels, and flexible side tapes in diaper designs, ensuring these high-stress components do not snap or delaminate during application.
Medical Stretch Bandages & Face Mask Earloops
Also widely applicable in the medical field for laminating elastic nonwoven composites, self-adhesive stretch bandages, and the secure bonding of flexible ear loops.
FAQ
1. Q: What is the creep resistance performance of your elastic hot melt adhesive?
A: Our adhesive delivers exceptional creep resistance, typically achieving less than 10%-15% creep (depending on testing conditions and coat weight) at 40°C for 4 hours, which is well within industry benchmarks for premium diapers.
2. Q: Which spraying methods are best compatible with this rubber glue?
A: It is perfectly suited for high-speed automated lines using continuous or intermittent spiral spray, meltblown coating, and omega-pattern (V-slot) applications from leading nozzle brands like Nordson or ITW Dynatec.
3. Q: Does the adhesive cause nozzle clogging or charring at high temperatures?
A: No. Thanks to its superior thermal oxidation stability, the adhesive does not degrade, discolor, or form char in the melting tank, significantly reducing downtime and nozzle maintenance costs.
4. Q: Is this adhesive safe for baby hygiene products?
A: Yes, absolutely. It is skin-safe, non-fluorescent, and complies with international safety regulations (REACH, RoHS), making it perfectly safe for close skin-contact products like baby diapers.
5. Q: Can I get tailored formulations based on our line speed?
A: Yes. We offer customized viscosity and open-time adjustments to match your specific production line speeds (e.g., 300m/min to 600m/min) and coating requirements.
