Introduction

pic01

NUCREL is an ethylene methacrylic acid copolymer manufactured and sold by Dow-Mitsui Polychemicals using US-based Dow Chemical Company technologies.

Since NUCREL contains polar groups in its molecular chain, in addition to toughness and flexibility it features excellent adhesion to glass, metals, etc.

Features

1. Toughness

As NUCREL has strong intermolecular bonds due to hydrogen bonding between carboxyl groups, it possesses a strength similar to ionomers and particularly excels in low-temperature impact resistance.

2. Flexibility

As NUCREL is an ethylene copolymer, it has moderate flexibility.

3. Adhesion to metal and glass

Since NUCREL contains polar, carboxyl groups, within its molecular chain, it exhibits excellent adhesion to metals such as aluminum foil and glass.

4. Thermal stability

NUCREL belongs to a category of ethylene copolymers with excellent thermal stability, is relatively stable against heat, and can be molded at temperatures of 300°C and higher depending on the processing method.

5. Weather resistance

As NUCREL is an ethylene copolymer, excellent weather resistance can be obtained by blending it with carbon black or a UV absorber.

6. Moisture absorbency

As NUCREL is not moisture absorbent, resin handling is simple.

7. Suitability as a packaging material

NUCREL is suitable as a sealant resin for packaging materials due to its excellent performance with various areas, including metal adhesion, heat sealing and hot tack properties.
