Final product types

• Frozen food bags
• Agricultural mulch films
• Vacuum packaging
• Lidding films for ready-meals

3. Cable and Wire Insulation Compounds

Producers of power cable and communication wire insulation rely on this EVA copolymer as a base resin for low-voltage insulation and sheathing grades. Its controlled vinyl acetate content ensures required flexibility and electrical insulating properties after compounding with flame retardants and stabilizers. The precise melt flow and absence of moisture trails reduce surface defects, supporting stringent downstream electrical testing protocols and compliance in both civil and industrial markets.

Industry compliance standards

• UL 62/UL 1581 (Flexible Cord and Wire Certification)
• RoHS (Directive 2011/65/EU)

Final product types

• Building wire insulation
• Flexible extension cables
• Telecommunication wire sheathing
• Low smoke zero halogen (LSZH) cable jackets

4. Solar Panel Encapsulation Materials

This EVA resin is processed into encapsulant films used in photovoltaic module assembly. Film makers require its exacting gel count, optical transmission, and crosslinking behavior to ensure secure lamination of solar cells and glass. After crosslinking in lamination ovens, the films provide the adhesion, electrical insulation, and UV durability required for long service life in outdoor PV installations. Our technical support aids clients in adjusting crosslinking agent masterbatch inputs during their extrusion and calendaring steps.
