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

Type	Functional Characteristics	Application Examples
Pressure-Sensitive Tapes (PSA)	Instant adhesion with light pressure, repositionable variants available	Packaging tapes, label adhesives, electronic component masking
Heat-Activated Tapes	Requires thermal energy to activate adhesive, high temperature resistance	Textile seam bonding, automotive HVAC systems
Double-Sided Tapes	Adhesive on both surfaces, varying carrier materials (film/foam)	Signage mounting, appliance assembly, medical device fixation
Foam Tapes	Viscoelastic properties, gap-filling capabilities	Automotive weatherstripping, window glazing, electronics shock absorption
Transfer Tapes	No carrier material, adhesive coated on release liner	Labeling systems, membrane switch assembly, cleanroom applications

3. Structure & Composition

Typical tape construction includes:

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

4. Key Technical Specifications

Parameter	Measurement Unit	Importance
Tack (Initial Adhesion)	N/25mm	Measures quick-stick properties for immediate bonding
Peel Strength	kN/m	Evaluates resistance to separation under 180 angle
Shear Strength	kPa	Determines load-bearing capacity under parallel stress
Temperature Resistance	C	Defines operational limits (-40 C to +200 C typical range)
Total Thickness	m	Impacts flexibility and gap-filling performance
Dimensional Stability	% change	Measures 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

Manufacturer	Key Products	Technical Highlights
3M	VHB 4945F	Acrylic foam tape with 6.0kN/m peel strength, 10-year durability
Tesa	Tesa 4651	Rubber-based PSA with 90 peel strength 4.5N/mm on steel
Scapa	ScapaFlex 710	Polymer blend adhesive for automotive paint masking
Nitto Denko	Nitto DS-422	Double-sided polyester tape for LCD module assembly
Avery Dennison	FP-800 Series	High-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
