Hot Melt Adhesive Pellets

Type

Key Features

Typical Applications

EVA (Ethylene-Vinyl Acetate)

1． Fast set-up: 3–8 second open time enables high-speed packaging and assembly lines.

2. Broad adhesion: bonds porous (paper, wood) and non-porous (plastics, metals) substrates without primer.

3. Wide temperature window: low-temp grades (110–130 °C) for heat-sensitive goods, standard grades (160–180 °C) for robust bonds.

4. Cost-effective raw base: 20–33 % VA content balances strength, flexibility and price for disposable or durable applications.

5. Formulation-friendly: readily accepts tackifiers, waxes and antioxidants to create custom viscosity, color and heat resistance.

6. Solvent-free & low VOC: meets ROHS/REACH requirements for food-contact cartons, hygiene non-wovens and toy assembly.

1 Carton & case sealing in food, beverage and e-commerce packaging lines

2 Bookbinding and spine gluing for soft-cover and catalog production

3 Edge-banding of MDF, particleboard and plywood panels in furniture manufacturing

4 Assembly of disposable diapers, sanitary napkins and medical non-woven products

5 Automotive interior trim lamination, wire harness tacking and filter element attachment

6 Craft, hobby and DIY projects using standard glue-gun sticks made from EVA granules

Polyolefin (APAO/PO)

1. Very low odor & VOC-ideal for sensitive indoor environments

2． Long open time (30 s – 5 min) plus adjustable set speed for large-area assembly

3. Excellent adhesion to low-surface-energy plastics (PP, PE) without surface treatment

4. Wide service-temperature window: flexibility down to –30 °C and heat resistance up to 90–100 °C

5. High chemical & moisture resistance, preventing bond failure in humid or oily conditions

6. Low density and clean machining: reduced stringing, nozzle clogging and equipment maintenance

1. Automotive interior trim-bonding PP/TPO dashboard skins, door panels and headliners

2. Filter assembly-pleating and end-cap sealing for air, oil and HVAC filters

3. Mattress and furniture construction-laminating non-woven cover stock to PU foam or pocket-spring units

4. Polypropylene packaging-case sealing, straw attachment and multi-wall bags

5. Hygiene and medical products-positioning adhesives for diaper leg elastics and surgical drape lamination

6. Insulation and construction-affixing PE vapor barriers, roofing membranes and thermal panels

Polyamide (PA, Nylon)

1. High strength & flexibility: delivers tough, resilient bonds that absorb dynamic loads and vibration

2. Wide temperature service range: maintains performance from –40 °C to +140 °C without embrittlement or creep

3. Superior resistance to oils, plasticizers, fuels and many solvents, ensuring durable bonds in harsh chemical environments

4. Fast crystallization gives short set-times (5–15 s) suitable for high-speed automated processes

5. Excellent adhesion to metals, leather, textiles, ABS and engineered plastics with minimal surface preparation

6. Renewable-source options available (castor-oil based PA 11/12) for reduced fossil content and improved sustainability

1. Electronics potting and encapsulation-wire tacking, coil fixing and PCB component reinforcement that survives reflow temperatures

2. Shoe manufacturing-upper-to-sole bonding, toe puff and counter attachment where oil-tolerant flexibility is required

3. High-temperature filter end-caps-securing synthetic media to galvanized or stainless steel plates in automotive and industrial filters

4. Automotive interior-headliner composite, trim clip retainers and cable harness clips exposed to engine-bay heat

5. Metal-to-plastic assembly-mounting ABS sensors, decorative trim and loudspeaker baskets with vibration-resistant joints

6. Industrial textiles-hemming conveyor belts, sewing-free seam sealing and bonding Kevlar®/aramid reinforcements

Polyester (PES)

1. Short open time (5–15 s) combined with high green strength for rapid, high-speed processing

2. Outstanding resistance to washing, dry-cleaning and elevated temperatures (up to 160 °C)

3. High cohesive and shear strength-forms tough, durable bonds on fabrics, metals and engineered plastics

4. Good chemical resistance to oils, plasticizers and common solvents, maintaining bond integrity in harsh environments

5. Low melt viscosity for excellent penetration into textile fibers and narrow gaps, ensuring strong mechanical anchoring

6. Thermally stable at application temperatures (180–200 °C) with minimal degradation, odor and smoke for clean production

1. Automotive headliner & door-panel lamination – fast tacking of decorative fabric to PU foam or PP substrate with wash-like heat aging resistance

2. Industrial laundry tags & RFID labels – bonding polyester or nylon labels that survive repeated 90 °C wash and tunnel-dry cycles

3. Seam sealing & hemming of workwear, sportswear and waterproof garments – sewing-free, flexible joints that withstand laundering and dry-cleaning

4. Elastic attachment in intimate apparel and medical textiles – secure, stretchable bonding of spandex/elastane to cotton or microfiber

5. Filter-bag manufacturing – joining polyester or aramid felt media with temperature- and chemical-resistant seams

6. Flexible printed-circuit reinforcement – mounting stiffeners to polyimide or PET films in high-temperature electronic assemblies
