1. Excellent temperature resistance: This is the most fundamental characteristic. The tape’s backing and adhesive must maintain stable physical and chemical properties at high temperatures, without softening, degradation, or loss of adhesion.
2. High adhesion strength: Even at elevated temperatures, the tape maintains a strong bond to various surfaces, including metals and plastics, ensuring reliable bonding.
3. High cohesion/shear strength: This is key to ensuring long-term bonding. The adhesive layer possesses strong cohesion, resisting shear stress caused by thermal expansion and contraction, as well as gravity, effectively preventing slippage or misalignment of the bonded objects at high temperatures.
4. Good weather and chemical resistance: Resistant to moisture, ultraviolet (UV) radiation, and common industrial solvents in the application environment, ensuring a durable bond.
The performance of high-temperature double-sided tape is determined by the combination of its carrier and adhesive. Different material combinations are suitable for a variety of high-temperature applications, from bonding internal electronic products to securing automotive parts.
1. Carrier
The carrier is the middle layer of double-sided tape. It provides a stable carrier for the adhesive and determines the tape’s thickness, strength, flexibility, and dimensional stability.
PET (Polyester Film):
Introduction: This is the most widely used carrier for high-temperature double-sided tape.
Features: PET is tough, ultra-thin, and dimensionally stable, resisting deformation when heated. It also offers excellent insulation and chemical resistance.
Applications: It is a workhorse for securing components within consumer electronics (such as mobile phones and tablets), attaching nameplates, and bonding flexible printed circuit boards (FPCs).
Carrier-less:
Introduction: This type of tape lacks an intermediate carrier and consists solely of a layer of high-performance acrylic adhesive. It is also known as transfer tape or VHB foam tape. Features: Highly bonded, it enables structural bonding. It also fills gaps in irregular surfaces, absorbs vibration, and distributes stress.
Applications: Attaching body trim in the automotive industry; attaching glass curtain walls in the construction industry; and achieving structural bonding in electronic products.
Tissue Paper:
Introduction: This tape is based on a flexible, thin tissue paper.
Features: The base material is very soft and easy to handle (hand-tearable), with good adherence to rough surfaces.
Applications: Widely used for attaching nameplates and decorative parts, as well as laminating foam and rubber materials. Its temperature resistance is relatively moderate.
PI (Polyimide Film):
Introduction: Based on a “gold finger” film, this is the highest-temperature-resistant double-sided film tape.
Features: It can operate for long periods in environments exceeding 200°C and offers excellent insulation properties.
Applications: It is used for laminating and attaching electronic components (such as flexible printed circuit boards) that require extremely high temperature resistance. II. Adhesive
The adhesive is the core factor that determines the adhesive strength, temperature resistance, and durability of a tape. For high-temperature double-sided tapes, high-performance acrylic adhesives are almost always used.
High-Performance Acrylic Adhesive:
Features: This is the absolute mainstream material for high-temperature double-sided tapes. Compared to ordinary acrylic adhesives, it has a more stable molecular structure and stronger cohesion. This allows it to:
Do not soften and flow, maintaining adhesive stability.
Slow viscosity decay, maintaining strong adhesion.
Strong holding power, resisting shear forces and preventing objects from slipping.
It also has excellent weather resistance, chemical resistance, and aging resistance, ensuring long-term bond reliability.
High-temperature double-sided tape is primarily used in the following applications:
1. Electronics Industry:
Core Application: This is its primary application area. It is used to secure internal components in devices such as smartphones and laptops, such as:
Attaching flexible printed circuit boards (FPCs);
Securing batteries, camera modules, and touch screens;
Bonding LED light strips to heat-dissipating aluminum substrates;
Attaching nameplates and membrane switches.
2. Automotive Industry:
Used for securely bonding automotive interior and exterior trim, such as:
Attaching body scuff strips and decorative trim;
Attaching vehicle nameplates and logos;
Securing onboard electronic modules.
3. Home Appliance Industry:
Used for securing components that generate heat during operation, such as:
Attaching evaporators and piping inside air conditioners and refrigerators;
Securing microwave oven door windows.
4. Solar Energy Industry:
Used for bonding laminates in solar panels, which must withstand high outdoor temperatures.
