Nichigo-POLYESTER™

Special Type

For Adhesion

Strongly adhesive polyester-based adhesives which do not cause corrosion in metals. Resistant to heat degradation, they can be used in a wide range of temperatures, and display extremely high heat resistance and durability. They offer strong adhesion with a range of materials including polycarbonate, PET, acrylics, and metals, and display particularly strong adhesion following heat seisitization.

Applications & Characteristics

  • Adhesive for heat resistance
  • Acid-free
  • Strong adhesion with thin coating
  • Plasticizer resistance

For Molding

Thermoplastic saturated polyester elastomers combining the characteristics of rubber and plastic. These products offer excellent molding workability and heat and cold resistance. This type possesses numerous excellent properties, including toughness, resistance to bending fatigue, and high oil resistance and chemical resistance.

Applications

  • Wire coating
  • hydraulic hose
  • cushioning

For Permeable Films

This type is able to form non-porous films displaying both waterproof performance and water vapor permeability performance. These products offer both a high level of permeability and excellent water resistance. Flexible and displaying the elasticity of rubber, they are also heat sealable

Applications

  • Permeable clothing such as sportswear and gloves
  • industrial components such as heat exchange elements
  • medical and hygienic applications including adhesive medicated plasters
  • surgical garments and paper nappies
