Hot melt specific-properties
Melt viscosity
One of the most noticeable properties. Influences the spread of applied adhesive, and the wetting of the surfaces. Temperature-dependent, higher temperature lowers viscosity.
Melt flow index
A value roughly inversely proportional to the molecular weight of the base polymer. High melt flow index adhesives are easy to apply but have poor mechanical properties due to shorter polymer chains. Low melt flow index adhesives have better properties but are more difficult to apply.
Pot life stability
The degree of stability in molten state, the tendency to decompose and char. Important for industrial processing where the adhesive is molten for prolonged periods before deposition.
Bond-formation temperature
Minimum temperature below which sufficient wetting of substrates does not occur.

Chemical Structure
Composition: Maleic Anhydride fuctionalized polyethylene mixture.
Application
LE910 adhesive resin is widely used as binder for plastic lined 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.
Advantages
1.Excellent bonding strength and wide range application, excellent chemical high adhesion with galvanized pipe, tinplate, stainless steel and other metals;
2.Maintain the excellent weather resistance and chemical resistance of polyolefin resin, and have excellent compatibility and excellent mechanical properties with PE, PE-X, PE-RT and other resins;
3.Excellent processability, good fluidity, and uniform glue coating;
4.Bright color and uniform pallets;
5. Hygienic and safe, no residue of toxic substances.
6.Ecxellent resistance to acid,alkali,salt atmosphere and other chemical materials.
