Typical usage ratio

• EVA is utilized within 22–35% loading by weight in halogen-free flame retardant cable compounds; the exact share varies based on the content of ATH (aluminum trihydrate) and required physical properties.

Downstream process integration

• Producers compound the resin with flame retardants and processing aids in internal mixers or twin-screw extruders, extrude the blend as granules, then feed directly into cable insulation or sheathing extrusion lines for continuous application over conductor wires or cable cores.

Final product types

• Low-voltage power cables
