CONSIDER NUCREL® FOR YOUR PACKAGING, INDUSTRIAL, AND CONSUMER APPLICATIONS.
DuPont™ Nucrel® is a family of ethylene-acid copolymer resins that provide outstanding, chemically-resistant bonds to metal and other materials. Nucrel® can be extruded, coextruded, or laminated on equipment designed to process polyethylene. DuPont is the only manufacturer of both ethylene-methacrylic acid (EMAA) based copolymers and ethylene-acrylic acid (EAA) based copolymers, creating the broadest product offering to enable a variety of applications.
PACKAGING APPLICATIONSNucrel® is a perfect choice where a strong bond to foil is required during extrusion coating or a strong bond to nylon is required during coextrusion. In addition, these resins offer heat sealability, hot tack strength, and ease of processing. DuPont™ Nucrel® resins are widely used in packaging applications including food and beverage, healthcare and personal care products. Examples of applications include aseptic packaging for liquids, condiment packaging, snack packaging, toothpaste laminates and pharmaceutical sachets.
INDUSTRIAL AND CONSUMER APPLICATIONSNucrel® can also be used in a variety of non-packaging applications, providing benefits similar to those found in packaging. Key industrial/consumer markets include wire and cable, mining, and footwear. Examples of industrial/consumer applications include adhesives for foil in cable jackets, stiffeners for the toe and heel areas in shoes, and adhesives in shock tubes in explosive detonator systems.
PROPERTIES OF NUCREL®
Adhesion• Offers excellent adhesion to foil, paper and other polar substrates, often eliminating the need for a separate primer
Product (Chemical) Resistance• Resists delamination and seal failure even in harsh (acidic) environments • Provides outstanding chemical resistance, which can result in longer shelf life• Offers good grease resistance
Heat Seal and Hot Tack Properties (Note: Higher acid content copolymers are preferred for better heat seal performance.)• Enables low seal initiation temperatures • Offers very good hot tack strength• Offers better sealing through contamination
Flexibility and Improved Processing• Allows for high speed extrusion coating and lamination due to higher melt strength• Can be pigmented, painted, or plated• Can be UV-stabilized for exterior applications• Can be used as a modifier and concentrate carrier• Can be foamed• Can be ground into powder for glass and metal coating applications

SPECIALIZED GRADES
DuPont offers specialized grades of Nucrel® resins that are formulated to improve important properties in both processing and product appearance:
• Nucrel® HS (High Stability/High Speed) grades allow for high-speed processing due to improved thermal stability and are capable of running at thinner coating thicknesses.• Nucrel® HC (High Clarity) film grades provide very low haze and high gloss for applications where transparency is important. • Nucrel® AE (Adhesion Enhancer) can be blended at 15-30% into LDPE, providing better metal adhesion or higher line speeds.
