EVA Hot Melt Glue And Polyolefin Hot Melt Glue | JCT Machinery

1. Melt Mixing System

EVA Hot Melt Glue Production Line: Use paddle reactor to achieve gentle mixing by low-speed stirring.

Polyolefin Hot Melt Glue Production Line: High shear equipment (such as sigma mixer) must be used to destroy the crystallization of polyolefin molecular chains.

2. Temperature Control System

EVA Hot Melt Glue Production Line: Heat transfer oil heating (120-150℃), ordinary PID temperature control.

Polyolefin Hot Melt Glue Production Line: High temperature heat transfer oil/electric heating (180-220℃), requires precise temperature control in sections (such as 5-zone temperature control of the barrel).

3. Molding and Cooling

EVA Hot Melt Glue Production Line:

• Underwater pelletizer: After the melt is extruded through the die head, it is directly cooled underwater and pelletized.

• Optional cold pressing into sheets (for block rubber).

Polyolefin Hot Melt Glue Production Line:

• Extrusion strand pelletizing: The melt is extruded through a porous die head and solidified through air cooling or water cooling tank before pelletizing.

• A cooling water circulation system must be equipped (to avoid thermal deformation of polyolefins).
