Nucrel 0910HS is an ethylene methacrylic acid (EMAA) copolymer resin produced by Dow Chemical. It combines the toughness of polyethylene with functional polar groups from methacrylic acid, providing excellent adhesion, flexibility, and heat-seal performance. It is widely used as a tie-layer resin in multilayer packaging films and aluminum foil laminates, as well as in hot melt adhesives and industrial bonding applications.

Key Features of DOW Nucrel™ 0910HS

  • Excellent adhesion to polar substrates such as aluminum foil, PA (nylon), PET and EVOH
  • Strong bonding to polyolefins (PE/PP) without the need for primers
  • High impact resistance and puncture resistance
  • Good chemical resistance (oils, acids, alcohols)
  • Excellent hot tack and heat-sealing performance
  • Good low-temperature toughness
  • Easy processing on standard extrusion equipment

Typical Application Areas

  1. Multilayer packaging films. Used as a heat-seal layer or adhesive layer in composite structures such as metallized films, aluminum foil laminates, and paper–plastic laminations.
  2. Tie-layer in composite film structures. Functions as a bonding layer for PE to metallized film, paper, or nylon (PA) in co-extrusion or extrusion lamination systems.
  3. Coating for metal or glass substrates. EMAA 0910HS provides adhesion and protective coating when applied to aluminum foil, metallized polyester film, or other rigid substrates.
  4. High-speed thin-layer packaging applications. Suitable for high-speed co-extrusion and thin adhesive layers in: metallized films, beverage packaging, toothpaste laminate tubes (ABL/PBL), wet wipe packaging films, liquid condiment sachets.
  5. Industrial bonding and functional materials. For example, cable shielding aluminum foil bonding, metal anti-corrosion coating, thermal lamination films, thin multilayer composites with metal/glass/fabric substrates.

Selection and Processing Recommendations

  • When selecting the grade, confirm whether the HS (High Stability / High Speed) version is required. For production lines featuring high line speed, high draw ratios, thin adhesive layers, or demanding thermal stability, Nucrel™ 0910HS is the preferred choice.
  • Processing temperatures should follow recommended settings, and die design, nozzle temperature, and cooling system configuration must be properly matched to ensure melt stability without degradation, gel formation, or delamination.
  • When used as a tie-layer resin in multilayer structures, optimize layer thickness, melt flow rate, extrusion ratio, die gap settings, and cooling strategy to ensure effective adhesion and overall laminate integrity.
  • For heat-seal applications, verify seal initiation temperature (SIT), hot tack strength, line speed compatibility, and contamination resistance (e.g. resistance to moisture, grease, powders during sealing).
  • For food contact applications, confirm regulatory compliance in the target region (e.g. U.S. FDA 21 CFR 177.1330) and ensure compliance of additives, masterbatches, and fillers used in the final structure.
  • During storage, handling, and processing, avoid moisture uptake and contamination. It is recommended to use dedicated extrusion equipment and follow proper purging and material changeover procedures.
  • When used in polyethylene-based systems (e.g. for lamination or film structures), compatibility with PE, bonding strength, and post-heat treatment performance should be evaluated.

Why Choose Nucrel™ 0910HS

Compared with the standard Nucrel 0910 grade, EMAA 0910HS offers enhanced performance in thermal stability, extrusion drawability, and thin-layer film processing. It is designed for high-speed extrusion coating and multilayer film structures where improved processing stability is essential. (Source: LookPolymers)

  • With an acid content of approximately 8.7% MAA, Nucrel 0910HS provides strong adhesion to metals and polar substrates while maintaining process efficiency.
  • Its melt index of ~10 g/10 min ensures good compatibility with conventional extrusion equipment and high production throughput.
  • Fully compatible with standard PE extrusion and co-extrusion lines, making it easy to integrate into existing manufacturing systems.
  • For lamination applications involving aluminum foil, metallized films, paper substrates, or functional multilayer films, DOW Nucrel™ 0910HS delivers a unique combination of: High Line Speed + Thin Coating Capability + Strong Adhesion.
