1. Hot Melt Adhesives for Packaging

Ultrathene UE642006X01 grade EVA serves as a foundational polymer in hot melt adhesive formulations for corrugated box sealing, product assembly, and kraft labeling. Its flow properties and flexibility at low temperatures increase speed during automatic line application and provide a secure seal in diverse climates without requiring high energy input for melting. Consistent pellet morphology allows for accurate metering during batch blending and continuous compounding, supporting tact time targets and minimizing downtime from viscosity drift.

2. Photovoltaic Encapsulant Sheets

The polymer's high transparency, elasticity, and weathering resistance enable encapsulant sheet manufacturers to deliver efficient solar modules with superior light transmission and long-term delamination resistance. Its uniform melt index allows for steady film extrusion, critical to process yield and minimizing scrap in high-throughput solar panel production environments. EVA sheets serve as the interface between PV cells and protective glass or backsheet layers, with tailored crosslinkability under thermal lamination.

Downstream process integration

• Directly extruded into sheets, followed by calendaring and online corona treatment for lamination stack-up; crosslink initiation occurs during module lamination cycle at 140–160°C

Final product types

• Pilot and mass-market solar panel encapsulant films
• Flexible encapsulation for building-integrated photovoltaics

3. Wire & Cable Insulation Compounds

In wire and cable production, this EVA type imparts electrical insulation, flexibility, and environmental durability to low-voltage and communication wiring for both residential and industrial sectors. Manufacturers benefit from the resin’s low gel content, leading to uniform thickness and robust dielectric performance after compounding and extrusion. The grade is well-suited for cable formulations requiring clean, contamination-free layers and compatibility with halogen-free flame retardant systems.

Industry compliance standards

• Low-voltage power wire insulation
• Flexible data and signal cables
• Halogen-free cable jackets and sheaths

4. Footwear Injection Molding Compounds

This EVA is a primary polymer base in injection-molded midsoles and outsoles for sports, safety, and casual shoes. Its balanced vinyl acetate content yields a foamable matrix with controlled hardness and high rebound, resulting in walkable comfort and durable performance after extended use. Our material streamlines foam compounding steps, with color and blowing agent dispersion up to industry cosmetic QC standards, and supports rapid demolding cycles in automated plants.

5. Flexible Film and Sheet Production for Food Packaging

Film producers rely on this grade for creating multilayer and monolayer food wraps, shrink films, and bagging solutions where puncture resistance and clarity preserve food integrity throughout storage and transport. The resin’s controlled melt viscosity enables consistent thickness, excellent sealability at low temperatures, and compatibility with LDPE and linear PE in coextrusion lines, boosting production uptime and pack-down strength on automated baggers.
