PUR type book binding glue is a reactive polyurethane hot melt adhesive used for book binding. It is an emerging book binding glue in recent years. It is regarded as a perfect upgrade product of the current mainstream EVA type book binding glue. The mature PUR type book binding glue has many advantages that the conventional EVA type book binding glue does not have, or it can well overcome many of the deficiencies inherent in the EVA type book binding glue itself. E.g:
1. Strong temperature adaptability: The temperature adaptation range of PUR type book binding glue is -40 ℃ ~ 150 ℃, while the temperature adaptation range of conventional EVA type book binding glue is -5 ℃ ~ 80 ℃. Under extreme temperature conditions, EVA-type book binding glue-bound books will cause many quality problems due to physical modification of EVA-type book binding glue. Books using PUR type book binding glue will not have these problems.
2. High bonding strength: The cohesive force of the book binding glue itself and the bonding strength between the glue and the paper are very important for the book binding strength. The cohesive force of EVA type book binding glue is ≈5N / cm; while the cohesive strength of PUR type book binding glue is ≥15N / cm. In terms of the strength of the adhesive force between the glue and the paper, PUR type book binding glue is (30 ~ 60)% higher than EVA type book binding glue. The most important thing is that these mechanical strengths of PUR-type book binding glue will not decrease significantly with the change of temperature.
3. Good flexibility: PUR-type book binding glue has good flexibility, and the amount of glue used is relatively small, so that the back adhesive is very thin, so the books and journals bound with PUR-type book binding glue are relatively EVA-type book binding Binding books is easy to be flattened, which brings a very pleasant experience for reading.
4. The cost is equivalent: the price of EVA-type book binding glue is about 1/3 of that of PUR-type book binding glue, but the amount is 3 times that of PUR-type book binding glue, so the cost of material loss between the two is roughly the same.
5. Other advantages: PUR type book binding glue has energy saving, environmental protection, labor saving, low defective rate, obvious competitive advantage of differentiation, obvious cost advantage of hardcover, and for different types of paper and different types of ink , Whether it is covered with film, whether it is UV varnished, etc., can be compatible with other situations; and the appearance of books bound with PUR type book binding glue is neat and beautiful.
