Final product types

• Greenhouse covering films (single and multi-season)
• Mulching films for row crops
• Thermal screens for horticultural climate control
• UV and anti-drip agricultural films

3. Wire & Cable Insulation Compounds

Major cable compounders select this EVA for insulation and sheathing of power, data, and hybrid cables requiring improved flexibility and electrical resistance.

• Building wiring plus commercial data cables
• Halogen-free flame retardant cable compounds

4. Solar Photovoltaic (PV) Encapsulation Sheets

Solar panel encapsulation processors utilize this EVA grade as the primary polymer in PV encapsulant sheets. Its consistent vinyl acetate content and cleanliness meet strict PID-resistance and optical clarity requirements for long module lifecycles. Exact crosslinking ratios and additive packages are engineered to maintain module integrity under extensive UV and damp-heat exposure.
