Tape

1. Overview

Tapes, adhesives, and material tapes are engineered bonding solutions combining substrates and adhesive layers for temporary or permanent joining applications. They enable rapid assembly, sealing, and reinforcement across industries. Modern advancements in polymer science and coating technologies have expanded their functionality beyond traditional mechanical fasteners, offering advantages in weight reduction, aesthetics, and process efficiency.

2. Main Types & Functional Classification

TypeFunctional CharacteristicsApplication Examples
Pressure-Sensitive Tapes (PSA)Instant adhesion with light pressure, repositionable variants availablePackaging tapes, label adhesives, electronic component masking
Heat-Activated TapesRequires thermal energy to activate adhesive, high temperature resistanceTextile seam bonding, automotive HVAC systems
Double-Sided TapesAdhesive on both surfaces, varying carrier materials (film/foam)Signage mounting, appliance assembly, medical device fixation
Foam TapesViscoelastic properties, gap-filling capabilitiesAutomotive weatherstripping, window glazing, electronics shock absorption
Transfer TapesNo carrier material, adhesive coated on release linerLabeling systems, membrane switch assembly, cleanroom applications

3. Structure & Composition

Typical tape construction includes:

  1. Base Material: BOPP (Biaxially Oriented Polypropylene), PET (Polyethylene Terephthalate), PVC, or foam substrates
  2. Adhesive Layer: Acrylic, rubber-based, silicone, or hybrid formulations (coated thickness 15-150 m)
  3. Primer Layer: Surface treatment for enhanced substrate adhesion (e.g., corona treatment for plastics)
  4. Release Liner: Silicone-coated paper/film for protection and dispensing

4. Key Technical Specifications

ParameterMeasurement UnitImportance
Tack (Initial Adhesion)N/25mmMeasures quick-stick properties for immediate bonding
Peel StrengthkN/mEvaluates resistance to separation under 180 angle
Shear StrengthkPaDetermines load-bearing capacity under parallel stress
Temperature Resistance CDefines operational limits (-40 C to +200 C typical range)
Total Thickness mImpacts flexibility and gap-filling performance
Dimensional Stability% changeMeasures resistance to thermal/humidity induced deformation

5. Application Fields

  • Electronics: Circuit board fixation, EMI shielding, component taping (SMT reflow ovens)
  • Automotive: Trim attachment, sensor mounting, battery cell bonding (EV powertrains)
  • Medical: Wound care dressings, ECG electrode attachment, sterile packaging
  • Construction: Pipe insulation sealing, membrane flashing, tile edge protection
  • Aerospace: Composite panel bonding, wire harness management, radar-absorbing material attachment

6. Leading Manufacturers & Products

ManufacturerKey ProductsTechnical Highlights
3MVHB 4945FAcrylic foam tape with 6.0kN/m peel strength, 10-year durability
TesaTesa 4651Rubber-based PSA with 90 peel strength 4.5N/mm on steel
ScapaScapaFlex 710Polymer blend adhesive for automotive paint masking
Nitto DenkoNitto DS-422Double-sided polyester tape for LCD module assembly
Avery DennisonFP-800 SeriesHigh-tack paper-based packaging tape with UV resistance

7. Selection Recommendations

  • Match adhesive chemistry to surface energy of substrates (e.g., silicone for low-energy plastics)
  • Evaluate environmental exposure (temperature, UV, chemical contact)
  • Consider application method (manual vs. automated dispensing systems)
  • Verify compliance with industry standards (UL 510 for electrical, ISO 10993 for medical)
  • Optimize cost-performance ratio through peel/shear strength trade-off analysis

8. Industry Trends

Key developments include:

  • Biodegradable base materials (cellulose/PLA composites) for sustainability
  • Electrically conductive adhesives for flexible electronics assembly
  • Temperature-indicating tapes with embedded thermochromic pigments
  • AI-driven adhesive selection platforms using material property databases
  • Increased demand for low-outgassing materials in EV battery manufacturing
