Applications of Levima FL00112 EVA in Industrial Manufacturing

Levima FL00112 EVA is a specialty ethylene-vinyl acetate copolymer, offering high processability and functional characteristics targeted at high-value industrial sectors. Our advanced polymer manufacturing ensures consistent quality required for demanding downstream production environments. Below, we outline the principal application scenarios and detailed technical integration paths in core industries.

1. Hot Melt Adhesives for Packaging and Bookbinding

Our EVA resin supports high-speed adhesive manufacturing lines by imparting desirable rheological profiles, rapid set times, and strong adhesion across substrates like paper, corrugated board, and films. Producers consistently select this grade in modern case sealing, carton closing, and hardcover bookbinding facilities due to its compatibility and cleanliness in formulation lines.

Industry compliance standards

• FDA 21 CFR 175.105 (Adhesives for food packaging)
• EU Regulation (EC) No. 1935/2004 (Food contact safety, adhesives)
• GB 9685 (Chinese food contact additive standards)
• REACH regulation (EC) No 1907/2006 (EU chemicals safety)

Typical usage ratio

• 28% – 40% by weight of total adhesive formula, adjusted for tackifier and wax content to match end-use bond strength, heat resistance, and open time requirements

Downstream process integration

• Direct incorporation into adhesive reactor or blending tanks; the polymer forms the foundational matrix during melt blending prior to addition of tackifiers, waxes, and stabilizers

Final product types

• Hot melt sticks, granules, and pillows
• Book spine adhesives
• Carton and case sealing adhesives for food, beverage, and household goods packaging lines

2. Wire and Cable Insulation Compounds

Cable compound formulators utilize our EVA grade to achieve essential dielectric characteristics, environmental stress crack resistance, and superior flexibility in communication and low-voltage power cable applications. It supports stable extrusion, controlled melt viscosity, and consistent matrix density for both residential and automotive cable types.

Industry compliance standards

• UL 62 / UL 1581 (Flexible Cords and Appliance Wiring Material Standards)
• RoHS Directive 2011/65/EU (Restriction of Hazardous Substances)
• IEC 60228 (Conductors for insulated cables)
• GB/T 2951 (Chinese cable insulation standards)

Typical usage ratio

• 35% – 60% by weight in insulation compound, with dosages tailored to target flexibility, flame retardance, and mechanical property specifications according to cable type

Downstream process integration

• Premixed with fire retardants, plasticizers, and antioxidants in a high-shear compounding extruder; the resultant pelletized compound is subsequently extruded around copper or aluminum conductors

Final product types

• Low voltage wire insulation jackets
• Power and control cable sheaths for industrial, building, and appliance wiring
• Automotive wiring harness insulation

3. Solar Cell Encapsulation Films

Levima FL00112 EVA supports manufacturers of photovoltaic encapsulant films by delivering controlled crosslinking performance, high optical clarity, and resistance to both UV exposure and hydrolytic degradation. Its melt flow characteristics allow for even film extrusion and bubble-free lamination on automated production lines.

Industry compliance standards

• IEC 61215 (Crystalline silicon terrestrial PV modules)
• UL 1703 (Flat-plate Photovoltaic Modules and Panels)
• GB/T 9535 (Chinese national PV module reliability standards)
• RoHS and REACH compliance for environmental safety in solar applications

Typical usage ratio

• 95% – 98% by weight in film extrusion blends, with crosslinking agents and additives finely tuned for required curing and module performance

Downstream process integration

• Direct feeding into specialized twin-screw extruders for extrusion casting or calendaring into thin encapsulant films; crosslinking initiated during the lamination of solar cell modules

Final product types

• Solar module encapsulant films
• Photovoltaic (PV) laminates for crystalline silicon or thin film modules

4. Footwear Injection and Foam Materials

Footwear and sporting goods manufacturers use our EVA resin in closed cell foaming and direct injection molding processes to achieve required cushioning, elasticity, and resilience. The polymer enables precision in foam cell structure, firmness, and end-use performance for durable midsoles and outsoles in mass production runs.

Industry compliance standards

• EN ISO 20345 / EN ISO 20347 (Safety and occupational footwear)
• GB/T 15107 (Chinese sports shoe standard)
• REACH and RoHS for restricted substances
• ASTM F2413 (North American footwear safety)

Typical usage ratio

• 55% – 85% by weight in foam formulation, varied by density, hardness, and mechanical property targets for different shoe types

Downstream process integration

• Blending with blowing agents, fillers, and pigments in batch mixers or extruders; subsequent injection or compression molding followed by physical or chemical foaming to form shoe components

Final product types

• Sneaker and running shoe midsoles
• Slippers, sandals, and molded foam soles
• Industrial safety shoe components

5. Film Blowing for Agricultural Greenhouse Films

Agricultural film producers select this EVA type to engineer greenhouse films that combine high light transmission with frost resistance and extended weatherability. The material’s melt properties and vinyl acetate content enable tailored optical properties and mechanical strength for wide-width, multi-season film blown extrusion lines.

Industry compliance standards

• GB/T 21661 (Chinese agricultural plastic film standard)
• EN 13206 (European greenhouse covering material standard)
• OECD Guidelines for Plasticulture Chemicals
• EU Regulation No. 10/2011 (Plastic materials intended to come into contact with foodstuffs for mulch and greenhouse films)

Typical usage ratio

• 8% – 22% by weight in multilayer co-extruded film blends, increased in cold climates or high-light transmission requirements

Downstream process integration

• Introduced through gravimetric feeders to film-blowing extruders in combination with LDPE/LLDPE and functional additives; blown into single or multi-layer greenhouse films

Final product types

• Greenhouse covering films
• Mulch and tunnel films for crop protection
