Nucrel 0910, also referred to as “0910 ACID”, is an ethylene methacrylic acid copolymer (EMAA) resin. It is a copolymer of ethylene (E) and methacrylic acid (MAA), with an MAA content of approximately 8.7 wt%. EMAA 0910 is mainly used for film extrusion, coating, co-extrusion layers, composite layers, heat-sealing layers, metal foil or paper coating, etc.

Key Properties of DOW Nucrel™ 0910

(1) Adhesion & Bonding Performance

  • Excellent adhesion to metals, aluminum foils, paper, PVC, nylon, and metallized films.
  • Provides strong heat-seal strength and good hot-tack performance.
  • Maintains performance even on slightly contaminated or moist surfaces.

(2) Chemical & Durability Resistance

  • Resistant to grease, oils, and mild chemicals.
  • Good long-term durability; does not easily become brittle, suitable for outdoor or long-term applications.

(3) Other Features

  • Low density supports lightweight applications
  • Compatible with standard PE systems
  • Can be dyed, coated, or metallized for decorative or protective uses

Typical Applications

  • Packaging Films: Heat-seal or tie layer in multilayer structures with aluminum foil, metallized film, or paper/plastic laminates
  • Metal/Glass Coatings: Adhesive layer on metal or glass substrates
  • Laminates: Tie layer for bonding PE or other plastics to metal/paper/film
  • Specific Packaging Products: Heat-seal bags, toothpaste tubes, snack packaging, wipes packaging

Why Choose Nucrel 0910 Grade?

  • Higher MAA content (8.7 %) improves adhesion to metals and polar substrates.
  • Moderate melt index (MI ~10) allows good extrusion and line speed.
  • Low melting point (100 °C) reduces heat-seal temperature and energy usage.
  • Excellent performance for bonding metal foils.

Selection & Processing Considerations

  1. Ensure extrusion temperature, die/mold temperature, and cooling rates are optimized for adhesion and thin-layer formation.
  2. Verify heat-seal start temperature, hot-tack, and seal width to match line speed and process conditions.
  3. Confirm regulatory compliance for food-contact applications in your region (e.g., 21 CFR 177.1330 in the US).
  4. Consider durability under outdoor or harsh conditions if applicable.
  5. Optimize layer thickness and processing speed when used as tie or lamination layer.
