Trends in binding hot melt adhesives and polyolefin adhesives: In recent years, the binding industry has had to adapt to many changes, including increasing production line speed and adopting polyolefin (POE) adhesives. Which products can help you meet the demands brought about by these developments and why?
Hot melt adhesive for faster binding line speed
High-speed book production, especially when bonding book spines with adhesive at low application temperatures, poses many challenges to adhesives. Hot melt adhesive must provide a strong adhesive force, but it should set fast enough to avoid dirtying the equipment during the finishing process, thereby avoiding the costly production downtime required for cleaning.
Specifically designed for use as low as 140°C Formulated for application at temperatures, they will operate safely on rapid production lines, bonding up to ” 10000 & have spent A magazine or book spine.
Why do bindings turn to polyolefins? (POE) Adhesive
Another trend in binding hot melt adhesives is the increasing use of polyolefin adhesives to replace alternative technologies such as PUR.
“
and ” PUR Unlike adhesives, polyolefin adhesives do not release harmful isocyanate-containing vapors into the workplace, so there is no need for a dedicated emission recovery system or preventive measures. In addition, they offer a faster solidification time, require less cumbersome internal management due to their longer pot life, and do not need to clean the melt tank and applicator (nozzle/roller) after each use.
Compatible with most hot melt equipment and processed in general municipal waste, polyolefin adhesives do not require additional equipment investment or waste disposal procedures.
For binding books and periodicalsHot melt adhesive granulesWhat model? Book and magazine adhesive packaging is not a universal use of particles. It is important to choose the appropriate model based on the paper type, thickness, and machine type. Below is a list of common models. List of adhesive models for books and periodicals General EVA […]
The curing speed and aging issues of EVA hot melt adhesive. Hot melt adhesive is a 100% solid adhesive without moisture and solvents. At room temperature, it is a solid and when heated to a certain degree, it becomes a fluid and viscous liquid adhesive. After melting, it appears as a light brown translucent body […]
Round particles vs cylindrical particles: a clear difference in appearance Comparison item Round particle (spherical) Cylindrical particles specific surface area Large, melts faster Slightly smaller, melting slightly slower Liquidity Excellent, not easily blocked by bridging materials Good, occasionally bridging bulk density 0.45-0.55 g/cm³ 0.50-0.60 g/cm³ Smoothness of feeding Excellent, automatic feeding Okay, some need to […]
Direct answer:Hot melt adhesive pelletsThe residual glue cannot be washed with water or ordinary alcohol. Commonly used are specialized hot melt adhesive cleaning agents (glue cleaning agents), high flash point white oil/mineral oil, and citrus terpene cleaning agents used in small quantities. The principle is to ‘soften with oil while hot, mechanically remove after cooling’, […]
