In the field of industrial bonding, sealing and electrical insulation, it is a continuous demand to find materials with high strength, durability, temperature resistance and environmental protection. Among them, polyester tape has become the cornerstone material of many industries with its excellent physical properties. In recent years, green polyester tape has received more and more attention due to its unique environmental protection attributes and equally excellent performance.
Polyester tape is a tape product made of polyester film as the substrate and coated with high-performance pressure-sensitive adhesive on one or both sides.
Core performance advantages:
Excellent mechanical strength:
The PET substrate gives the tape extremely high tensile strength, tear resistance and dimensional stability, which is not easy to deform or break, providing reliable physical protection.
Excellent temperature resistance:
Polyester tape can usually withstand a wide temperature range of -20°C to 220°C (or even higher), and can still maintain good adhesion and physical properties in high temperature environments, will not melt or soften excessively, and is not easy to become brittle at low temperatures.
Good electrical insulation:
PET film itself is an excellent insulating material, which makes polyester tape widely used in insulation protection, coil bundling, PCB covering, etc. in the electronic and electrical industry.
Chemical and weather resistance:
Good resistance to a variety of chemicals (such as solvents, greases), ultraviolet (UV) and humid environments, extending service life.
Thin and strong: It can provide strong protection with a relatively thin thickness, save space and be flexible in application.
Transparent or colored options:
The substrate can be made transparent or in various colors to meet the needs of identification, aesthetics or specific functions.
Typical application areas of green polyester tape
Thanks to its high performance and environmental protection characteristics, green polyester tape is widely used in:
Electronic and electrical industry:
PCB board insulation protection and shielding: Covering gold fingers, protecting pads, wave soldering shielding.
Wire harness bundling and identification: Replace halogen-containing PVC electrical tape to bundle wire harnesses and provide insulation.
Transformer, motor, coil insulation: Interlayer insulation, outer layer protection.
Lithium battery insulation and fixation: Insulation between battery cells, ear protection, battery pack fixation.
Home appliance manufacturing: Internal wire harness fixation, insulation, temporary fixation of components.
Automotive manufacturing: wiring harness bundling, identification, interior parts fixing, sensor protection.
New energy (photovoltaic, wind energy): solar panel assembly insulation, sealing, junction box protection; internal insulation of wind power equipment.
Industrial manufacturing: metal sheet protection, sandblasting masking, pipe bundling and identification, equipment nameplate pasting.
Communication equipment: optical cable bundling, internal insulation and fixing of equipment.
Key considerations for selecting green polyester tape
Environmental certification: explicitly require suppliers to provide halogen-free test reports, as well as declarations or reports that comply with regulations such as RoHS and REACH.
Core performance parameters:
Thickness: affects flexibility and strength.
Tensile strength & elongation at break: reflects mechanical properties.
Peel strength: the size of the adhesive force.
Temperature resistance level: the highest long-term use temperature and short-term peak temperature.
Dielectric strength: a key indicator of electrical insulation capability.
Chemical resistance: select according to the application environment.
Adhesive type: acrylic adhesive (good versatility, good weather resistance), rubber-based adhesive (high initial adhesion) or silicone (excellent high temperature resistance)? Is it low VOC?
Substrate color and transparency: Green is a common logo, and transparent or other colors are also available.
Supplier qualification and reliability: Choose a reputable supplier who can provide stable quality and compliance certificates.
