Melt glue stick

1. Material Composition

Our hot melt adhesive sticks are made from advanced thermoplastics including:

Ethylene Vinyl Acetate (EVA): For general purpose bonding, it is flexible and can bond porous materials such as cardboard, wood and fabrics.

Polyolefin (PO): Designed for challenging substrates such as polypropylene (PP) and polyethylene (PE), ensuring chemical and moisture resistance.

Copolyamide (CoPA): High-performance formulas with 60-80% bio-based content, heat resistance (>150°C), oil resistance and durability for automotive and electronic applications.

Biodegradable Options: Eco-friendly hot melt adhesive sticks with 45% bio-based content, certified for biodegradability according to ASTM D6400, and approved by the FDA for indirect food contact.

2. Temperature Performance

High-Temperature Glue Sticks: Work at 163-204°C (325-400°F), ideal for heavy-duty industrial bonding.

Low-Temperature Glue Sticks: Work at 121-149°C (250-300°F), ideal for heat-sensitive materials like foam or delicate fabrics.

3. Sizes & Compatibility

Standard Sizes: 5/16-inch (7 mm), 1/2-inch (12 mm), 5/8-inch (15 mm), 1-inch (25 mm), and 1.75-inch (43 mm) glue sticks.

Special Sizes: Compatible with 3M Polygun TC, LT, and PG II Systems for high-volume applications.

4. Color Options

White, Yellow, Clear: Makes edge banding of furniture panels invisible.

Colored Hot Melt Glue Sticks: Vibrant colors, including black, red, blue, gold, and silver, can be used for decorative or functional labels.

Black hot melt glue stick: UV resistant and opaque, ideal for automotive and architectural applications.

Glitter and metallic: provide aesthetic solutions for crafts and high-end packaging.

5. Certification and safety

FDA food grade compliant, can be used for indirect food contact.

Available in UL94 V0 flame retardant formulation for electronics.

REACH and RoHS compliant.

Production Process

1. Raw Material Synthesis

Ethylene and vinyl acetate monomers are polymerized under controlled conditions to create EVA pellets.
Bio-based copolyamides are synthesized from dimerized fatty acids and diamines.

2. Compounding & Additive Integration

Polymers are blended with tackifiers (e.g., terpene-phenol resins), waxes, and stabilizers.
Fumed silica (5–8%) is added to reduce stringing and improve sag resistance.

3. Extrusion & Forming

Molten adhesive is extruded into rods and cooled under precision temperature controls.
Quality checks ensure diameter consistency (±0.1mm) and defect-free surfaces.

4. Packaging

Sticks are sealed in moisture-resistant boxes with tamper-proof labels.
