I. Definition of adhesive tape<\/strong>
Pressure sensitive tape means that the tape adheres easily to the surface being adhered by touch and light pressure. Pressure sensitive tape is a viscoelastic polymer with both liquid and solid properties. Therefore, compared with glue, adhesive tape does not need to be cured during bonding, which can save man-hours. Tapes are used in a wide range of fields. In addition to daily office tape products, tapes are also used in many industrial fields such as automobiles, electronics, paper printing, construction, home appliances, new energy, and rail transit.<\/p>\n\n\n\n

II. The structure of the tape<\/strong>
Adhesive tapes generally consist of coatings with various functions. The adhesive is applied to one or both sides of the substrate (to make single- or double-sided tapes). The following diagrams show typical constructions of single-sided or double-sided tapes.<\/p>\n\n\n\n

III. Types of substrates<\/strong>
The task of the substrate is to hold the adhesive and primer. The base material is very rich, from paper to plastic film, etc. Different materials have different characteristics and are suitable for various application scenarios.<\/p>\n\n\n\n

Common substrates:<\/p>\n\n\n\n

    \n
  1. Film tape (PP, PET,PVC)
    Dimensionally stable, chemically stable, temperature resistant (PET), transparent or white
    Non-woven tape
    Docile, heat-resistant, hand-tearable, transparent<\/li>\n\n\n\n
  2. Foam tape (PE)
    Vibration and noise reduction, suitable for rough surfaces, compensates for thermal expansion and contraction between different materials (such as glass and metal), black or white<\/li>\n\n\n\n
  3. Cloth\/fabric tapes are compliant, scratch-resistant, hand-tearable, and have a high amount of glue.<\/li>\n\n\n\n
  4. Asymmetric Tape
    Differential adhesives are coated on both sides of the substrate, resulting in different peel forces on both sides.<\/li>\n\n\n\n
  5. Non-backing tape
    There is no base material, only the adhesive is attached to the release paper, which has excellent conformability and is very thin.<\/li>\n<\/ol>\n\n\n\n

    IV. Types of adhesives<\/strong>
    The coating weight (g\/m2) and formulation of the adhesive depends on the application for which the tape is designed.
    Common adhesives are acrylic adhesives, natural rubber adhesives and synthetic rubber adhesives. Different adhesives have different basic characteristics, and acrylic adhesives are generally better suited for permanent and outdoor applications.
    Comparative analysis of two main adhesives:<\/p>\n\n\n\n

    Acrylic Adhesive:<\/p>\n\n\n\n

      \n
    1. Advantages
      Excellent adhesion to polar materials (PET, PC, glass, metal)
      Heat resistant
      Aging resistance
      Can withstand various environments
      Typically higher shear resistance at elevated temperatures<\/li>\n\n\n\n
    2. Limitations
      Final bond strength is achieved after a rest period, so repositioning is possible
      low initial bond strength
      Relatively low adhesion to polar materials<\/li>\n<\/ol>\n\n\n\n

      Rubber adhesive:<\/p>\n\n\n\n

        \n
      1. Advantages
        High initial viscosity
        Realize fast bonding with the adherend
        Excellent adhesion to non-polar surfaces such as PP, PE, or EPDM<\/li>\n\n\n\n
      2. Limitations
        Relatively low high temperature resistance
        Relatively low aging resistance
        Relatively low environmental performance
        Relatively low chemical resistance
        Relatively low moisture resistance<\/li>\n<\/ol>\n\n\n\n

        V. Types of release paper\/film<\/strong>
        The type of material of the release paper determines its physical properties, such as tensile strength, elongation, tear resistance, moisture resistance stability, cutting debris\u2026 The release force of the release paper\/film should not be too large to cause tape It is difficult to peel off, and it should not be too small to fall off.<\/p>\n\n\n\n

        Common release paper\/film:<\/p>\n\n\n\n

          \n
        1. Cellophane
          tearable
          good tensile strength
          Good electrostatic discharge performance
          The paper core is relatively hard and has strong compressive stability
          die cut
          cost-effective<\/li>\n\n\n\n
        2. PE coated paper
          high dimensional stability
          PE coating prevents moisture absorption
          tearable
          good tensile strength
          Good electrostatic discharge performance
          die cut<\/li>\n\n\n\n
        3. MOPP film

          Moisture-proof
          Small thickness tolerance
          die cut
          translucent<\/li>\n\n\n\n
        4. PE film
          Good elasticity, suitable for wrapping thicker products
          Moisture-proof<\/li>\n\n\n\n
        5. PET film
          High temperature resistance (up to 150\u00b0C)
          Small thickness tolerance
          dimensionally stable, thin
          die cut
