PE Pellet Hot Melt Adhesive Granules Excellent Processability

Grade:LE910

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

Decriptions

Hot-melt glues usually consist of one base material with various additives. The composition is usually formulated to have a glass transition temperature (onset of brittleness) below the lowest service temperature and a suitably high melt temperature as well. The degree of crystallization should be as high as possible but within limits of allowed shrinkage. The melt viscosity and the crystallization rate (and corresponding open time) can be tailored for the application. Faster crystallization rate usually implies higher bond strength. To reach the properties of semicrystalline polymers, amorphous polymers would require molecular weights too high and, therefore, unreasonably high melt viscosity; the use of amorphous polymers in hot-melt adhesives is usually only as modifiers. Some polymers can form hydrogen bonds between their chains, forming pseudo-cross-links which strengthen the polymer.

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.
