1, block and granular hot melt adhesive

This hot-melt colloidal particle yields the most. Blocky is a square, round block, granular is flat, diamond, cylindrical. Color has weak yellow, white, red, black or translucent colorless wait. When using, there should be a glue pot, after melting, scraping, roller coating, spraying or extrusion coating.

2, bar hot melt adhesive

It is usually a round rod shaped rubber strip with a length of 150 to 300mm. The glue coating tool is to insert the end of the rubber strip of the hot melt gun into the barrel of the gun, and pull the trigger after being hot melted to push the rubber strip forward and extrude the fused glue at the same time. This glue has yellow, white, red, or colorless transparent mainly used for bonding metal, electronic products, plastic parts and toys.

3, powder hot melt adhesive

Mostly used for fabric and liner, must be achieved through the powder device "coating" glue. When agglutination, glue lining material and other base material overlap, through hot pressing, can achieve close agglutination. If clothing uses agglutination lining, carpet back lining, leather shoes lining. The pulverization of hot melt glue is more difficult, because of the friction and fever when mechanical pulverization will appear sticky block, need to use chemical pulverization and cryogenic mechanical pulverization method. Color is mostly natural.

4, film hot melt adhesive

The hot melt adhesive is extruded into thin film sheet into roll products, cut into the required size when used, sandwiched between the base material by hot pressing can achieve high bonding strength. The film can also be combined with heat cured components, such as epoxy resin or crosslinking agent. Transparent film used for automotive laminated safety glass manufacturing and solar cell packaging. They have polyurethane film, polyvinyl butyral film, EVA film. Transparent film is not required for the bonding of boards on automobiles and airplanes.
