Typical usage ratio

• 20–45% by weight in hot melt adhesive formulations, adjusted based on required viscosity, flexibility, and application temperature; content increases for more elastic bonds or low-temperature flexibility.

Downstream process integration

• Premixed with tackifier resins and waxes in heated mixers; melted and compounded during hot melt adhesive production; pumped to filling units for pellets, pillows, or blocks; finally applied via hot glue dispensers on packaging lines.

Final product types

• Hot melt adhesive pellets, pillows, and blocks
• Case and carton sealing adhesive sticks
• Food tray, folding box, and beverage carton adhesives
• Envelope sealing adhesives

2. Wire and Cable Primary Insulation

The material is a preferred base resin for low voltage wire and cable insulation, particularly for applications requiring enhanced flexibility and safety. Its fine particle size and melt flow allow consistent extrusion, which is essential for insulation layers that must meet electrical and flame retardancy standards in appliances, building wiring, and data cable production lines.

Industry compliance standards

• UL 1581 (Reference Standard for Electrical Wires, Cables, and Flexible Cords)
• RoHS Directive (2011/65/EU) for hazardous substances restriction
• IEC 60227 and IEC 60332 (Flame retardancy and flexibility for cable insulation)
• CSA C22.2 No. 49 for control and instrumentation cables

Typical usage ratio

• 40–65% by weight in insulation compounds, with the ratio set according to required elongation and dielectric strength; fillers and flame retardants are blended as needed for specific end-use certifications.

Downstream process integration

• Compounded with stabilizers and flame retardants in twin-screw extruders; pelletized and fed to continuous extrusion lines for uniform coating around copper or aluminum wires; cooled and spooled prior to downstream jacket application.

Final product types

• Electrical wire insulation for household and commercial wiring
• Flexible appliance cable insulation
• LAN and telecommunication cable insulation layers
• Control and signal cable primary sheathing

3. Solar Panel Encapsulant Sheets

This EVA grade is formulated into encapsulant sheets that protect solar cells against moisture, mechanical impact, and UV degradation, supporting high light transmittance and adhesive strength after lamination. Precision blending with crosslinking agents ensures process stability during continuous lamination cycles in photovoltaic module fabrication plants.

Industry compliance standards

• IEC 61215 (Crystalline silicon terrestrial photovoltaic modules – Design qualification and type approval)
• UL 1703 (Standard for Flat-Plate Photovoltaic Modules and Panels)
• IEC 62788-1-1 (Encapsulant characterisation)
• ISO 14001:2015 for environmental management in module production

Typical usage ratio

• 50–80% by weight in encapsulant sheet formulations; exact percentage set by required crosslinking density, optical clarity, and peel strength after lamination; ratio fine-tuned for different module architectures.

Downstream process integration

• Compounded with crosslinking peroxides and UV stabilizers in extrusion lines; calendered into films or sheets; laminated under vacuum and heat between solar cells and glass or backsheet layers; cured and trimmed in full-module assembly lines.

Final product types

• Phtovoltaic module encapsulant sheets
• Double-glass solar module encapsulants
• Backsheet-laminated solar panels
• Flexible thin film module encapsulation

4. Foam Footwear and Sports Sole Compounds

The product is widely adopted in manufacturing lightweight, shock-absorbing foam soles for sports shoes, sandals, and occupational footwear. Its controlled vinyl acetate content improves foamability and compression set, delivering soft, resilient materials compatible with high-pressure injection and continuous sheet foaming processes used by leading footwear brands.

Industry compliance standards

• ISO 20344 (Personal protective equipment – Test methods for footwear)
• GB/T 15107-2013 (Chinese standard for EVA foamed shoe material)
• EN 71-3 (Migration of certain elements for children's shoes)
• Prop 65 (California Safe Drinking Water and Toxic Enforcement Act for restricted substances)

Typical usage ratio

• 45–80% by weight in foam recipes, with dosage modulated for targeted hardness, cell structure, and compression; blowing agents and colorants blended for process-specific requirements.

Downstream process integration

• Dry-mixed with foaming agents, fillers, pigments, and zinc stearate in kneader mixers; extruded or molded in injection machines; foamed via steam or chemical blowing; trimmed and assembled with upper shoe components on automated conveyors.

Final product types

• Socks and midsoles for running shoes
• Slipper and sandal foamed soles
• Anti-fatigue mats and insoles
• Children’s shoe foam bases

5. Flexible Film for Greenhouse and Agricultural Coverings

Our material supports industrial extrusion of flexible films for greenhouse and tunnel coverings, facilitating exceptional light transmission, tear resistance, and longevity under UV exposure. Compounders target a balance between mechanical toughness and controlled degradability, aligning with precise agricultural film requirements for climate control in intensive cultivation.
