High Tackiness Crystal Gel

Physical properties

●Features

  • The hardness of the material is JIS hardness type E with three grades: 15, 20, and 25 degrees.
  • The material has high transparency and can be freely colored.
  • The material is highly flexible at temperatures ranging from -20°C to +80°C, and has excellent shock absorption properties.
  • Excellent adhesion to steel, aluminum, glass, plastic and other materials.
  • Excellent seismic isolation properties due to high adhesiveness.
  • Excellent releasability and non-transferability, and when soiled, adhesive properties are restored by washing with water.

●Applications

  • Insole applications: Pads to prevent bunions, pads to prevent shoe sores, pads to prevent heel lift, pads to prevent heel cracking, arch pads, etc.
  • Office automation equipment: Cushioning materials for seismic isolation, gel washers for sound reduction, etc.
  • Home care applications: Vibration-isolating and shock-absorbing sheets for furniture, home appliances (TVs), glass and ceramic products, etc.
  • Other applications: Fine powder adsorption sheets, beauty care products, processed sheets for various mats, etc.

●Processing method

  • Extrusion molding
  • Injection molding
  • Laminate molding
