Reactive polyurethane adhesive / PUR Adhesive Used For Making Bras
/ Pur Adhesive are widely used in apparel, lingerie, sportswear, and technical textiles due to their flexibility, durability, and strong bonding without stitching. They are especially popular in seamless bonding, laminates, and stretchable fabrics.
✅ Superior Flexibility – Moves with fabric, ideal for stretchy materials (e.g., bras,
activewear).
✅ Strong Wash & Dry-Cleaning Resistance – Withstands repeated laundering better than EVA or acrylic
adhesives.
✅ Heat-Activated Bonding – Applied via hot-melt guns, heat presses, or laminating machines.
✅ Seamless & Lightweight – Replaces stitching in bonded seams, hems, and decorative trims.
✅ Eco-Friendly Options – Some PUR adhesives are REACH-compliant, solvent-free, and low-VOC
Usage Instructions
Common Applications in Women's Underwear:
Seamless panties
Bra cups & padding attachment
Elastic bonding (waistbands, leg openings)
Lace and fabric bonding
Advantages Over Traditional Adhesives:
Better heat and moisture resistance than standard hot melt
adhesives.
No harmful solvents (eco-friendly option).
Long-lasting performance even with frequent washing.
Considerations When Using PUR Glue
Requires heat application (usually 110–160°C).
Must cure properly for maximum durability.
Should be tested for fabric compatibility (some synthetics may
melt).
