Electrical insulating crepe paper and polyester tape, also known as polyester film (Mylar) tape, are two different types of electrical insulation tapes commonly used in the industry.
Crepe paper tape is made from insulating crepe paper which is coated with a rubber-based or acrylic adhesive. This type of tape has excellent electrical insulation properties and is commonly used for coil winding and insulation in transformers, motors, and other electrical equipment. It can also provide a degree of water resistance and can be used for temporary splicing or repairing of cables.
Polyester tape, on the other hand, is made from a thin layer of polyester film (Mylar) coated with an acrylic adhesive. This type of tape has high dielectric strength, good chemical resistance, and excellent dimensional stability. It is commonly used for electrical insulation and cable wrapping, and also as a heat-resistant masking tape for powder coating and other high-temperature applications.
Both types of tape have their own unique properties and are suitable for different applications depending on the requirements of the project.
