Packaging tape is primarily made from BOPP (biaxially oriented polypropylene) film as the base material, and then coated with a pressure-sensitive adhesive emulsion through a heating and uniform application process. The main component of the pressure-sensitive adhesive emulsion is butyl ester.
Different types of electronic tapes have different storage lives, which are mainly affected by factors such as the tape's composition, quality, and storage conditions. Generally, properly stored electronic tapes can maintain good performance for a certain period of time. Below are some common types of electronic tapes and their approximate storage lives:
In daily life, we use a lot of tape, and over time, removing it leaves stubborn tape residue. No matter how old or large the tape residue is, a few drops of nail polish remover (the kind used by women to clean nail polish) can be applied. Let it soak for a while, then wipe it with a tissue, and the surface of the item will be as good as new. However, there's a problem: because nail polish remover is highly corrosive, it cannot be used on surfaces that are susceptible to corrosion, such as painted furniture or laptop casings. Therefore, while nail polish remover is very effective at removing tape residue, you must be careful to protect the affected item from corrosion.
When choosing double-sided tape, you need to consider the application scenario, the materials being bonded, performance requirements (such as adhesion and temperature resistance), and budget. The following provides a detailed guide covering application scenarios, core parameter analysis, material comparison, and purchasing tips to help you make the right choice:
High-temperature tape refers to adhesive tape used in high-temperature working environments. Primarily used in the electronics industry, its temperature resistance typically ranges from 120°C to 260°C. It is commonly used in spray painting, baking paint, leather processing, coating masking, fixing electronic components during manufacturing processes, and masking for printed circuit boards and high-temperature treatments. High-temperature tapes include Kapton high-temperature tape, PTFE high-temperature tape, high-temperature masking tape, PET green high-temperature tape, and high-temperature double-sided tape.
The adhesive strength of transparent tape is not absolute and is affected by various factors such as adhesive type, thickness, and application scenario. Specifically, it can be analyzed from the following aspects:
