PET double-sided tape is based on PET film and coated with acrylic acid or silicone adhesive on both sides. Its core advantages are stable dimensions, wide temperature resistance, strong shear resistance, moisture resistance, chemical resistance and insulation — and it is easy to die-cut and adapt to batch special-shaped assembly.

Consumer Electronics & 3C Precision Manufacturing

Adapting to the requirements of lightweight, high precision and clean assembly.

Fixation of Core Components

Used for fixing lithium batteries and battery compartments of mobile phones and tablets (ultra-thin 0.03mm, space-saving and displacement-prevention). Fixes FPC, PCB, camera modules and micro motors with even pressure to prevent deviation. Black shading variants prevent light leakage in camera modules.

Bonding of Optical Components

Bonds LCD/LED screens to middle frames and fixes light guide plates and reflective films in backlight modules (transparent models ≥90% light transmittance, no bubble overflow). Suitable for fixing lenses and keys of smart watches and headphones — easy to rework after removal with no residual adhesive.

Attachment of Auxiliary Components

Seamless attachment of nameplates and LOGOs to enhance texture. Fixes dust screens, sensor grounding pieces (insulation does not interfere with circuits). Silicone rubber series bonds low surface energy materials such as silicone rubber and PP, solving antenna and NFC module fixation challenges.

Automobile Industry

🌡️ Meets requirements for high/low temperature resistance, vibration resistance, environmental protection and no odor — covering both interior and exterior component fixation.
Interior Assembly

Bonds center consoles, door trim panels (environmentally friendly adhesive, VOC-free, meets interior standards). Fixes ambient lights, sound insulation cotton and wiring harnesses (shock absorption and noise reduction). Flame-retardant models are suitable for interior areas near fire sources.

Exterior Decoration Fixing

Pastes automobile nameplates and window trim (UV and rain resistant, no degumming or yellowing long-term). Fixes rearview mirror decorative covers without drilling, reducing process steps and preventing corrosion. High-temperature models (≥200℃) fix engine compartment wiring harnesses under thermal radiation.

Vehicle-Mounted Electronics

Bonds dashcams, ETC devices and other in-vehicle electronics (easy installation, no residual adhesive upon removal, no damage to car body or glass).

White Goods & Smart Home Manufacturing

🏠 Meets requirements for temperature resistance, waterproofing and batch automatic assembly across a wide range of home appliance applications.
Fixing the Control Panel

Bonds touch panels and display screens for refrigerators and air conditioners (transparent models do not obstruct the view; waterproof, sealed and short-circuit resistant). Fixes air outlet grilles and temperature/humidity sensors (resistant to alternating high and low temperatures for accurate detection).

Sticking of Functional Parts

Fixes sealing strips and heating tubes of high-temperature household appliances such as ovens and water heaters (V-0 flame retardant, stable and non-aging at high temperature). Bonds nameplates and foot pads (easy to die-cut, adapts to complex shell shapes, improves assembly efficiency).

Frequently Asked Questions
Q What is the difference between PET and PVC carrier in double-sided tape?
A PET (polyester) carrier offers superior dimensional stability, higher temperature resistance (up to 150°C short-term), transparency and chemical resistance — making it ideal for precision electronics and automotive applications. PVC carrier tapes (such as HY6970 and HY6968) are milky in color, more flexible and suited for applications that require a softer, conformable bond without extreme heat demands.
Q What thickness of PET double-sided tape should I choose for my application?
A The right thickness depends on your application requirements. Thinner tapes (30–80μm, e.g. HY6983, HY6972, HY6980) are ideal for ultra-slim electronics such as smartphones and tablets where space is critical. Mid-range thicknesses (100–160μm) suit general bonding in consumer electronics and automotive interiors. Thicker tapes (205–325μm) provide greater adhesive volume for uneven surfaces or heavier components in white goods and automotive exterior parts.
Q Can PET double-sided tape bond low surface energy materials like silicone rubber or PP?
A Yes. Standard acrylic adhesive models may have limited adhesion to low surface energy (LSE) materials. However, the silicone rubber series variants within the PET double-sided tape range are specifically formulated to bond LSE substrates such as silicone rubber and polypropylene (PP), making them suitable for antenna and NFC module fixation in consumer electronics.
Q Is PET double-sided tape suitable for automotive exterior applications exposed to UV and rain?
A Yes. PET double-sided tape is designed to withstand UV radiation, rain and outdoor environmental exposure without degumming or yellowing over long periods. It is widely used for bonding automobile nameplates, window trim strips and rearview mirror decorative covers, providing a durable, corrosion-free alternative to mechanical fastening methods.
Q What is the maximum temperature resistance of PET double-sided tape?
A For PET carrier models (HY6983 to HY6965), the long-term heat resistance is 100°C and the short-term heat resistance is 150°C. High-temperature models designed for engine compartment applications can withstand temperatures of ≥200°C, making them suitable for wiring harness fixation under high-temperature radiation in automotive environments.
Q Can PET double-sided tape be die-cut into custom shapes for automated assembly?
A Absolutely. One of the key advantages of PET double-sided tape is its excellent die-cutting performance. It can be precisely cut into complex custom shapes and sizes to meet the demands of automated batch assembly processes in consumer electronics, white goods and automotive manufacturing — significantly improving production efficiency and consistency.
