High Adhesive Strength Hot Melt Glue Granules White

Product Specification

Grade:LE910

Product:Hot Melt Adhesive granules for Plastic line Pipe and Steel Plastic Composite Pipe

Decriptions

Adhesive granule is functionalized polymer, is designed to provide high adhesion to both metals and polyolefins when use as a thermal lamination film and binder. It provide excellent adhesion to bond plastic with metal included Fe, Zn and Al. Those polymer materials can be tightly bonded to other materials while matintaining some excellent polymer materials by adding some special polar function groups that make it strong adhesion and still maintain good characteristics.

The adhesives are usually clear or translucent, colorless, straw-colored, tan, or amber. Pigmented versions are also made and even versions with glittery sparkles. Materials containing polar groups, aromatic systems, and double and triple bonds tend to appear darker than non-polar fully saturated substances; when a water-clear appearance is desired, suitable polymers and additives, e.g. hydrogenated tackifying resins, have to be used.

Increase of bond strength and service temperature can be achieved by formation of cross-links in the polymer after solidification. This can be achieved by using polymers undergoing curing with residual moisture (e.g., reactive polyurethanes, silicones), exposure to ultraviolet radiation, electron irradiation, or by other methods.

Resistance to water and solvents is critical in some applications. For example, in textile industry, resistance to dry cleaning solvents may be required. Permeability to gases and water vapor may or may not be desirable. Non-toxicity of both the base materials and additives and absence of odors is important for food packaging.
