Wood working and furniture/Mattress applications
Hot melt adhesives (HMAs) are crucial for woodworking, furniture, and mattresses, using base resins like EVA, APAO, or PUR for applications like edge banding, lamination, foam bonding, and upholstery, offering quick setting, versatility, and stronger bonds than some traditional glues, replacing hazardous solvent-based options for healthier, more durable products in everything from cabinetry to spring mattresses.
Key Types & Applications
| EVA (Ethylene Vinyl Acetate): | Common for general woodworking, edge banding (PVC/melamine), and basic furniture assembly, providing good adhesion and fast setting. |
| APAO (Amorphous Poly Alpha Olefin): | Excellent for mattress applications (foam lamination, ticking) and furniture, known for high heat resistance and flexibility. |
| UR (Polyurethane Reactive): | Premium choice for high-strength, durable bonds in veneering, panel lamination, and demanding furniture assembly, offering moisture curing for superior strength and longevity. |
For Woodworking & Furniture
| Edge Banding: | EVA and APAO HMAs create strong, durable bonds for decorative edges on particleboard/MDF. |
| Panel Lamination: | PUR and EVA bond veneers, laminates (like HPL), and decorative foils to substrates. |
| Assembly: | Bonding wood to wood, wood composites, and even plastics for frames, cabinets, and decorative elements. |
For Mattresses & Upholstery
| Foam Bonding: | HMAs securely join different foam layers (e.g., memory foam, polyfoam). |
| Spring Pocketing: | Specialized HMAs provide high adhesion and heat resistance for assembling pocketed coils. |
| Fabric & Ticking: | Bonding mattress ticking and upholstery fabrics to foam and frames. |
Hot Melt Types and Applications
| Adhesive Type | Woodworking Furniture | Mattress Manufacturing | Key Properties & Benefits |
|---|---|---|---|
|
PUR (Polyurethane Reactive) |
Excellent for edge banding, panel lamination, and structural assembly. Provides strong, water-resistant bonds, often replacing traditional formaldehyde glues. |
Used for demanding applications requiring strong, durable bonds with high heat and chemical resistance. |
* Forms an exceptionally strong, permanent bond upon moisture curing. * High resistance to heat, water, and chemicals. * Low VOC emissions, environmentally friendly. |
|
EVA (Ethylene-vinyl Acetate) |
Commonly used for general assembly, edge banding, and non-structural uses. Provides fast setting and ease of use. |
Used in general assembly and for bonding various foam and fabric materials. Offers rapid setting times, suitable for high-speed lines. |
* Fast-setting and cost-effective. * Versatile and easy to use in standard glue guns/equipment. * Good balance of tack and strength. |
|
APAO (Amorphous Poly-alpha-olefin) |
Used in office furniture for foam binding and non-structural assembly. |
Widely used for foam lamination, pocket coil assembly, and upholstery. Known for flexibility, long open times, and low odor. |
* Excellent flexibility, preventing cracking with movement. * Low melting points, safer for heat-sensitive materials like foam. * Low odor and low VOC. |
|
Polyamide (PA) |
Used for high-strength applications and wood repairs like knot filling. |
Less common in general mattress assembly but can be customized for specific, high-performance needs. |
* Higher heat resistance and strength compared to EVA. * Excellent toughness |
