| General and high-speed packaging | GB/T 16998-1997 | Melt viscosity (180°C): 3,000 – 15,000 mPa·s (lower for packaged types, which is beneficial for high-speed spraying) | Temperature resistance: -30°C to 60°C (operating temperature range) | Environmental friendliness:100% solids contentSolvent-freeEnvironmentally friendly and non-toxic | Opening time: 3 – 15 seconds (high-speed packaging typically ≤ 5 seconds) |
| Softening point (Ring & Ball): 75 – 95°C | Low temperature resistance: Good; it retains a certain degree of toughness without becoming brittle at low temperatures. | Safety: RoHS certified; some models meet food packaging hygiene requirements. | Curing speed: Instant – 10 seconds |
| Tensile strength: 3.0 – 5.0 MPa | Aging resistance: Generally, prolonged exposure to outdoor ultraviolet radiation will cause aging. | | Construction temperature: 150 – 180°C |
| Hardness (Shore A): 60 – 80 | | | Application: Suitable for high-speed production lines such as automatic glue spraying and roller coating. |
| Woodworking and textile special type | | Melt viscosity (180°C):Woodworking type: 10,000 – 25,000 mPa·s (high viscosity, anti-sagging); Textile type: 5,000 – 12,000 mPa·s | Heat resistance (woodworking type): High, to withstand the thermal environments the furniture may come into contact with. | Environmental friendliness: Non-toxic and odorless, safe for human health. | Opening hours:Carpentry type:10 – 30 seconds(For easy alignment adjustment); Textile type: 5 – 15 seconds |
| Softening point: Woodworking type: 85 – 100°C; Textile type: 70 – 85°C (lower, more flexible) | Washability (textile type): Good, can withstand multiple washes or dry cleaning (depending on the specific formulation). | Special considerations: Textile types require consideration of dye compatibility. | Application temperature: Woodworking type: 160 – 190°C; Textile type: 140 – 170°C (avoid scorching fabrics) |
| Flexibility: Excellent for textile applications, resistant to repeated bending; woodworking type exhibits good initial tack and creep resistance. | Oil resistance: The wood-based type has a certain degree of oil resistance. | | Application methods: Woodworking type is suitable for manual or automatic glue application; textile type is suitable for scraping and spraying. |
| Binding-specific type | | Melt viscosity (180°C):8,000 – 20,000 mPa·s (balancing flowability and impermeability) | Aging resistance:It maintains bonding strength over a long period, without yellowing or becoming brittle (for high-quality binding). | Environmental friendliness:Non-toxic and meets safety standards for school supplies. | Opening time: 5 – 25 seconds (providing ample processing time) |
| Softening point: 70 – 85°C | Low-temperature resistance: Excellent, preventing the adhesive layer of books from becoming brittle and cracking during low-temperature storage. | Low odor: No odor during heating and use. | Curing speed: Medium, ensuring full impregnation of paper fibers. |
| Adhesion: Exhibits extremely high adhesion to paper, cardboard, and linerboard. | Reversibility (partially DIY type): Some formulas are designed to be reversible, facilitating manual adjustments. | | Application temperature: 130 – 160°C (lower to prevent burns to the operator and avoid scorching of the paper) |
| Color: Usually white or transparent to avoid the color showing through and affecting the appearance. | | | Application: Suitable for manual glue guns and small glue spraying equipment. |
