As industrial development, PET tape for electronics and automotives become a reliable choice for
demanding environment .with excellent resistance to heat, chemical & mechanical stress, it ensures
good performance in precision assembly.This article explores themain advantages of PET tape for
international B2B buyer & engineer.
1.The Essential Layer of PET tape
PET tape is called Polyester tape, which is made from pet film coated with acrylic or silicone adhesive.
The Essential Layers are PET film backing and adhesive layer.
(1) PET Film Backing: it is backbone of the tape, delivers key important features.
-Superior Tensile Strength:With stand tearing and stretching ,last long time in mechanical environment.
-Excellent Dimensional Stability:PET film also has good stability for complex tasks such as component
masking or accurate splicing.
-Preferred Electrical Insulation : its high dielectric strength is indispensable for safeguarding electrical
components and ensuring
operational safety in circuits.
(2)Adhesive Layer: The type of adhesive coating highly influence PET tape performance. There are two
types .
-Acrylic Adhesive: it is commonly used pressure-sensitive adhesive (PSA) which is reliable initial tack,
outstanding aging resistance,excellent weatherability, and strong bonding across diverse substrates. Acrylic-based PET tapes typically perform well in continuous temperatures -20~120°C.
-Silicone Adhesive: This PSA is specifically for its unrivalled high-temperature resistance, often with
standing up to 200°C or more in short time. It is applied in precision masking because of its residue-free
removal
2.Eco-friendly PET tape is widely used in electronics and automotive manufacturing.
(1) PET Tape for Electronics :Precision,Protection
-PCB masking:high temperature PET tape is used in wave soldering and reflow soldering,the color is
usually green and blue.Use in masking gold fingers and sensitive components of Printed PCB.
-Electric Insulation: Widely used for electrical insulation to securing windings in transformers,inductors
and small motors. High dielectric insulation substantially reduces the risk of short circuits
-Component Holding:Offer secure, temporary,vibration dampening, or permanent fixing of discrete
components like capacitors or resistors onto circuit boards or within enclosures.
-Battery Pack Assembly:Insulating and Taping of Individual Batteries and Battery Packs.Enhancing safety
and thermal management within portable electronics and EVs.
(2)PET Tape Automotive: Exceptional Reliability and Performance
-High-Temp Paint Masking: Ideal for masking windows,door jambs and other surfaces for high-temp baking
cycles at automotive paint shop. It resists temperatures up to 200°C without melting or leaving an adhesive residue for a top-quality finish.
-Wire Harnessing: PET tape for wire harnessing is suitable for wire harnesses wrapped within the
throughout vehicle,from the engine room to the passenger cabin. It offers stable adhesion ,heat resistant, insulation and protection .
-Temporary Component Holding: Used during assembly processes to temporarily hold components, trims,
or cables in place before final fixing, ensuring efficient line operations.
-Surface Protection: Applies as a temporary protective layer on painted surfaces or sensitive components
during transit or assembly to prevent scratches, chips, or minor impacts.
