Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tapes, in particular to an adhesive tape with good high temperature resistance effect. Background Art

[0002] Tape, as a common adhesive product, is widely used in daily life and industrial fields. It is usually composed of a substrate, an adhesive and a release paper or a release film. The substrate is mostly made of plastic film, cloth or paper to ensure the strength and toughness of the tape. The adhesive provides strong adhesion and can firmly bond various materials. The release paper or release film is used to protect the adhesive surface for easy use. There are many types of tapes with different functions, such as double-sided tape, insulating tape, cloth-based tape, etc. They are suitable for different application scenarios. In the fields of packaging, logistics, electronic manufacturing, construction, etc., tapes play an indispensable role. They can fix objects, seal packages, protect circuits, etc., providing great convenience for all walks of life.

[0004] Although the above scheme is easy to use and convenient for tearing off the tape, the high temperature resistance of the tape is not ideal when used in some higher temperature environments.

At the same time, when torn by external force, the tape is prone to breakage or damage, which cannot meet the requirements of long-term or high-load use. Therefore, it does not meet the existing needs. In this regard, we have proposed a tape with good high temperature resistance. Utility Model Content
