What Is PET Tape?
PET tape uses polyethylene terephthalate polyester film as the backing and normally uses heat-resistant silicone pressure-sensitive adhesive for high-temperature industrial applications.
The thin, strong film produces a neat edge and remains easy to identify on the production line. It can mask surfaces during powder coating, painting, electroplating and selected electronics processes, and can also provide temporary protection, fixing, insulation or film splicing when the adhesive construction matches the job.
Temperature must always be considered together with time. Standard PET tape is often used around 180°C, while selected grades may withstand 200°C, 220°C or 230°C for a short cycle such as 30 minutes. For longer exposure, repeated cycles or higher-temperature soldering, compare the process with a suitable polyimide tape before approval.

PET Tape Custom Service
The correct PET tape depends on where and how it is used. Aluminum, stainless steel, glass, plastic, solder mask, painted surfaces and silicone-treated release liners can respond differently to the same adhesive. Powder type, plating chemistry, temperature ramp, dwell time, cooling method and removal timing also affect the result.
Guangzhou Huayun Manufacturing can supply full-width material, slit rolls and drawing-based converted parts. Send the required width, length, core, winding direction, color, backing thickness, total thickness and packing method. For die-cut parts, include a dimensioned drawing and clearly mark the adhesive side.
Clean removal is achieved by matching the tape to the process. A sample trial on the production substrate is recommended before bulk supply, especially on anodized aluminum, textured powder coating, soft paint, engineering plastics or silicone-sensitive surfaces.

PET Tape Buyer and Technical FAQs
Practical answers for purchasing, process engineering, quality and production teams before testing or placing an order.
What is PET tape made from?
High-temperature PET tape normally uses a PET polyester-film backing coated on one side with heat-resistant silicone pressure-sensitive adhesive. Green is the most common color because it is easy to see during application, inspection and removal.
What temperature can PET tape withstand?
Standard working references are commonly around 180°C. Many short-term grades are listed at 200°C for 30 minutes, while selected constructions may reach 220–230°C for 30 minutes. These higher figures are model-specific and do not represent continuous operating temperatures.
What is the difference between PET high-temperature tape and polyimide tape?
PET tape is a practical choice for many powder-coating, painting, plating and moderate heat processes. Polyimide tape is generally considered when the process has a higher peak temperature, longer exposure or soldering profile. Selection should also compare thickness, stiffness, adhesion, residue, dielectric needs and cost.
Will PET masking tape remove without adhesive residue?
A suitable PET silicone tape is designed for clean removal after a compatible process, but residue depends on substrate, surface condition, pressure, dwell time, temperature, coating chemistry, cooling and removal method. Test the actual production surface before a bulk order.
Which PET tape thicknesses are commonly available?
Common total-thickness references include 0.05, 0.06, 0.07, 0.08 and 0.09 mm. Selected models are also available in 0.055, 0.095, 0.10 mm and other constructions. The backing and adhesive coating should be confirmed separately.
Can width, roll length and core size be customized?
Yes. Tape can be slit to custom widths from master material up to approximately 500 mm wide. Common roll lengths are 33 m and 66 m, while selected constructions can be supplied up to approximately 200 m.
Can PET tape be supplied as die-cut masking parts?
Yes. PET masking tape can be converted into tabs, discs, plugs, frames, sheets and custom shapes. Send a dimensioned drawing, identify the adhesive side and state the liner, pull tab, sheet layout and packing requirement.
Which colors are available?
Transparent green is the standard color for many PET tapes. Clear, blue, red, yellow, white and black may be available with different film thicknesses or adhesive constructions. Color should not be used as the only way to identify performance.
Is PET tape suitable for powder coating and baking paint?
It is commonly used for powder coating and baking-paint masking when the oven profile fits the selected grade. A production trial should check edge lifting, paint anchorage at the boundary, film shrinkage, removal force and residue after cooling.
Can PET tape be used on PCB and electronic parts?
It can be used for compatible masking of gold fingers and contact areas, temporary component holding and insulation. Do not assume every PET tape is suitable for wave soldering or high-peak reflow. Verify the actual temperature profile, dielectric requirement, ionic cleanliness, residue and any silicone-contamination restriction.
How should the tape be applied and removed?
Apply to a clean, dry surface with even pressure and avoid stretching the film around corners. Follow the approved removal temperature and pull angle. Remove smoothly rather than jerking the tape, and check whether the process requires removal while warm or after cooling.
How should PET tape be stored?
Store sealed in a cool, dry area away from direct sunlight, heat, dust and solvent vapors. Keep rolls in their original packaging and use the confirmed shelf life. If material has been stored for a long period, retest adhesion and removal before production.
What should we send for an accurate quotation?
Please send the required total thickness, width, roll length, core, color, quantity, substrate, surface finish, process chemical, peak temperature, heating time, cycles, removal requirement and packing. Include an existing tape sample, data sheet, masked-part photo or die-cut drawing when available.
