Characteristics of Granular Hot Melt Adhesive | JCT Machinery

◪ Physical State

Granular hot melt adhesives are solid at room temperature and have a granular or pelletized form. They become molten and adhesive when heated

◪ Composition

Typically composed of thermoplastic polymers, resins, waxes and additives. The specific formulation can vary based on the intended application.

◪ Melting Point

These adhesives have a defined melting point, and they transition from a solid to a liquid state when heated to the required temperature.

◪ Viscosity

In their molten state, granular hot melt adhesives exhibit a low viscosity, allowing them to flow and penetrate surfaces for effective bonding.

◪ Quick Setting

One of the key advantages is the rapid setting time. As the adhesive cools and solidifies, it quickly forms a strong bond, contributing to efficient production processes.

◪ Versatility

Suitable for bonding a wide range of materials, including paper, carboard, fabric, wood, plastics and more.

◪ No Solvents

Unlike solvent-based adhesives, hot melt adhesives are solvent-free, reducing environmental and health concerns associated with solvent exposure.

◪ Ease of Application

The granular form allows for easy handling and application. These adhesives are commonly used with hot melt glue guns or other dispensing systems.

◪ Cleanliness

Because they solidify quickly, there is minimal mess or waste during application. This cleanliness is advantageous in high speed production environments.

◪ Temperature Sensitivity

The adhesive's performance is closely tied to temperature control. Maintaining the appropriate temperature is curcial for consistent bonding.
