The principle of die-cutting for graphite sheet heat dissipation materials

High-temperature tape, also known as heat-resistant tape, refers to adhesive tape used in high-temperature operating environments. It is primarily used in the electronics industry, with temperature resistance typically ranging from 120 degrees to 260 degrees. It is commonly used in paint spraying, paint baking leather processing, masking during painting, and for securing and masking during electronic component manufacturing processes, as well as in printed circuit boards and high-temperature processing. Types of high-temperature tapes include KAPTON high-temperature tape, Teflon high-temperature tape, high-temperature masking tape, PET green high-temperature tape, and high-temperature double-sided tape. Definition of high-temperature tape: basic knowledge of high-temperature tape.

       Dongguan double-sided adhesive tape manufacturers specialize in producing high-temperature resistant double-sided adhesive tape with die-cutting. The tape, made of cotton paper substrate coated with acrylic adhesive on both sides, features strong adhesion, stable durability, environmental friendliness, easy cutting, conformability, and die-cutting processing. It is widely used for bonding and fixing various metals, plastics, films, panels, foam die-cutting, toys, household items, decorative parts, dustproof and waterproof materials, insulation and shielding materials, etc.

III. Instructions for Use:

It does not have spontaneous combustion properties when exposed to air. In case of fire, water spray, foam, carbon dioxide, and dry powder can be used to extinguish the fire.

IV. Storage conditions:

1. Properly store in an environment with a temperature of 25 degrees Celsius and a humidity level of 60%, avoiding direct sunlight.

2. High-temperature adhesive is made of a die-cut strip of heat dissipation material. Its actual substrate is a brown PET film coated with silicone. Since the actual application temperature in some industries does not need to be too high, not exceeding 260 degrees, and the high temperature resistance of PET is 220 degrees, it is generally not easily noticeable. What's worse, some use other adhesives instead of silicone, which have a temperature resistance far below 150 degrees.

It specifically depends on the raw material of the substrate: polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), or other raw materials.
