One: reactive hot melt adhesive
This kind of hot melt adhesive has common adhesive properties and low temperature melting characteristics, especially suitable for wood bonding. Because the wood structure sparse structure, easy expansion and leakage of glue, water in wood is also easy to surface dispersed, under such conditions, the reaction type hot melt adhesive to air and moisture in the wood and fully mixed, and achieve the full reaction process, so as to obtain liquidity and wettability of the biggest, so viscosity and adhesive strength can reach the best standard.
Two: water dispersed hot-melt amines
Some paper products to maintain a clean appearance in adhesive after in the production process of recycled paper and recycled, hot melt adhesive elements contained in the filter is easy to be removed, such as bookbinding, use the product in the process of adhesive glue is water dispersion type hot melt adhesive, the adhesive is the biggest in plastic hardening can easily be removed, very suitable for bookbinding and paper packaging will need to remove the glue bonding process but not by means of high temperature heating process.
Three: re wetted hot melt adhesive
The glue has been widely used in the life and work of a hundred times. It is not known to each other, such as the bonding of post office letter seal, and the production of the label.
Four: hot-melt pressure sensitive adhesive
In recent years, hot melt pressure sensitive adhesives, because of their solvent free, safe and environmental protection and simple operation, have been popular, and have been widely praised by many manufacturers and customers.
According to the composition of HMPSA are divided into two kinds, one is the basic material for hot melt pressure sensitive adhesive with ethylene vinyl acetate copolymer resin for a long, the other is a thermoplastic elastomer polymer as hot-melt pressure-sensitive adhesive material, usually used as packaging tape, labels, sanitary napkins, medical infusion paste. Plaster bandage, medical tape, and so on are used after a HMPSA.
