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 natures of the polymer and the additives used to increase
tackiness (called tackifiers) influence the nature of mutual
molecular interaction and interaction with the substrate. In one
common system, EVA is used as the main polymer, with terpene-phenol
resin (TPR) as the tackifier. The two components display acid-base
interactions between the carbonyl groups of vinyl acetate and
hydroxyl groups of TPR, complexes are formed between phenolic rings
of TPR and hydroxyl groups on the surface of aluminium substrates,
and interactions between carbonyl groups and silanol groups on
surfaces of glass substrates are formed. Polar groups,
hydroxyls and amine groups can form acid-base and hydrogen bonds
with polar groups on substrates like paper or wood or natural
fibers. Nonpolar polyolefin chains interact well with nonpolar
substrates. Good wetting of the substrate is essential for forming
a satisfying bond between the adhesive and the substrate. More
polar compositions tend to have better adhesion due to their higher
surface energy. Amorphous adhesives deform easily, tending to
dissipate most of mechanical strain within their structure, passing
only small loads on the adhesive-substrate interface; even a
relatively weak nonpolar-nonpolar surface interaction can form a
fairly strong bond prone primarily to a cohesive failure. The
distribution of molecular weights and degree of crystallinity
influences the width of melting temperature range. Polymers with
crystalline nature tend to be more rigid and have higher cohesive
strength than the corresponding amorphous ones, but also transfer
more strain to the adhesive-substrate interface. Higher molecular
weight of the polymer chains provides higher tensile strength and
heat resistance. Presence of unsaturated bonds makes the adhesive
more susceptible to autoxidation and UV degradation and
necessitates use of antioxidants and stabilizers.
