• Granulation and pelletizing for hot melt glue stick and block converters

Final product types

• Case and carton sealing adhesives
• Perfect bound books and magazine adhesives
• Envelope and label glues
• Consumer glue sticks

3. Wire and Cable Insulation Compounds

Wire and cable manufacturers use this EVA in low-voltage electrical insulation and jacketing compounds.

Downstream process integration

• Compounded on co-rotating twin screw extruders with continuous melt filtration
• Direct pelletizing and feeding to cable insulation extrusion lines under nitrogen blanket to suppress oxidation

Final product types

• Insulated residential wires (building wiring)
• Automotive low-voltage harnesses
• Flexible control and instrumentation cables
