PETtape

一、Core Structure and Basic Characteristics

typical structure 

• Substrate layer: BOPET film (thickness 5 μ m-500 μ m), providing mechanical strength and dimensional stability
• Adhesive layer: acrylic, silicone or rubber pressure-sensitive adhesive (thickness 5 μ m-100 μ m)
• Release layer: Gracin paper, PET release film, protective layer for easy use

core advantage

• Excellent temperature resistance: Ordinary acrylic adhesive series has long-term temperature resistance of -40 ℃~120 ℃ and short-term resistance of 140 ℃~200 ℃; Silicone adhesive system can withstand 180 ℃ for a long time and up to 204 ℃ in a short time
• High mechanical strength: The tensile strength is 3-5 times that of BOPP tape, the elongation at break is low, and it is not easily deformed
• Good chemical stability: acid and alkali resistant, solvent resistant, grease resistant, anti-aging and UV resistant
• Excellent electrical insulation: breakdown voltage can reach 20kV/mm or more, suitable for electronic insulation applications
• Dimensional stability: Shrinkage rate<1% under high temperature and pressure, high die-cutting accuracy
• Transparent and beautiful: Light transmittance>90%, suitable for application scenarios that require visual effects

Main drawbacks

• Price higher than ordinary BOPP tape
• Under low temperature conditions (<-20 ℃), the viscosity will significantly decrease
• Some rubber products may have residual rubber after high temperature
• The bonding effect on low surface energy materials (such as PP, PE) is average

二、detailed classification

Classified by adhesive type

Classified by function and structure

• Single sided PET tape: the most common type used for masking, protection, insulation, and fixation
• Double sided PET tape: double-sided coated adhesive used for bonding, adhesion, and assembly
• PET high-temperature tape: using high-temperature resistant substrate and silicone adhesive, used in high-temperature processes
• PET insulation tape: adding insulation coating, used for insulation of motors, transformers, and wires
• PET anti-static tape: surface resistance of 10 ^ 6~10 ^ 11 Ω, used for ESD protection in the electronics industry
• PET shading tape: black or silver gray, used for shading LCD backlight modules
• PET mesh exhaust tape: The adhesive layer has a micro grid structure, which automatically exhausts without bubbles during bonding
• PET fiber tape: composite glass fiber, extremely strong tensile and tear resistance
• PET aluminum foil Mylar tape: PET and aluminum foil composite, with shielding, thermal conductivity, and insulation properties

四、Key technical parameters

五、Buying Guide

1. Select based on the operating temperature
   • ≤ 80 ℃: water-based acrylic adhesive system (low cost)
   • 80 ℃~120 ℃: Oil based acrylic adhesive system (with good comprehensive performance)
   • 120℃~204℃：Silicone adhesive system (high temperature resistant and residue free)

   • 204℃：Suggest choosing PI polyimide tape

2. Select based on the surface of the adhered object
   • Smooth high surface energy materials (glass, metal, PC, ABS): medium low viscosity is sufficient
   • Rough surface (wood, stone, fabric): high viscosity or rubber based
   • Low surface energy materials (PP, PE, PTFE): require specialized primer or special adhesive system
3. Select based on functional requirements
   • Insulation: Choose insulated PET tape and pay attention to breakdown voltage indicators
   • Anti static: Choose products with surface resistance of 10 ^ 6~10 ^ 11 Ω
   • Light shielding: Choose black or silver gray light shielding PET tape
   • High temperature process: Choose silicone adhesive based high-temperature PET tape
4. Select based on thickness
   • Ultra thin (≤ 30 μ m): suitable for bonding precision electronic components and thin products
   • Medium thickness type (30 μ m~100 μ m): universal type, suitable for most applications
   • Thick (>100 μ m): Suitable for scenarios that require buffering, filling, or high-strength bonding

六、Precautions for use and storage

Key points of use

• The surface of the adhered object must be clean and dry, free from oil stains, dust, and moisture
• Apply uniform pressure during pasting (it is recommended to use a scraper or roller) to ensure that the adhesive layer is in full contact with the object being pasted
• The optimal pasting temperature is 15 ℃~35 ℃, avoid construction in environments below 10 ℃
• After high-temperature application, it is recommended to remove the tape before it cools to room temperature to achieve the best residue free effect
• For important applications, it is recommended to conduct small-scale testing first

Storage conditions

• Store in a cool and dry place at a temperature of 15 ℃~25 ℃ and a relative humidity of 40%~60%
• Avoid direct sunlight and high temperature heat sources
• The original packaging is sealed and stored, with a shelf life of generally 6-12 months
• When storing, it should be placed vertically to avoid deformation of the tape under pressure
