The existing pressure sensitive tape

The existing pressure-sensitive tape cannot meet the environmental requirements of high temperatures and humidity.

In recent years, with the development of the national economy and scientific and technological level, the adhesive has become an indispensable new material in the development of high and new technology and has been widely used in various sectors of the national economy and related fields of daily life. With the development of China’s industry, the application field of adhesives has been expanding, from mainly used in wood processing, clothing, light industry, construction, and packaging industries to new energy, machinery manufacturing, aerospace, electronic and electrical appliances, transportation, environmental protection and energy saving, medical and health and many other fields, has become an indispensable important chemical product in the national economy and people’s life. Adhesive tape is a specific structure of pressure sensitive adhesive and a variety of thin materials. It is one of the tools often used to fix parts in daily life and work.

According to its function, it can be divided into high temperature tape, double-sided tape, conductive tape, special tape, pressure sensitive tape and die cutting tape. With the thinning and globalization of electronic products, electronic products demand more and more adhesive tape, and more and more strict, adhesive tape in electronic products increasingly prominent importance.

At the same time, the tape also put forward more physical requirements, such as enhanced universality, not only to metal, PET and other easily adhesive surface bond stability, but also to PE, PP or PC with glass fiber adhesive strong; It should meet the needs of temperate and tropical environments as well as cold regions such as the north and Europe. With the opening of the global market, the export of many electronic products increases, resulting in more and more electronic products need to meet the requirements of high temperature and humidity environment, but the adhesive tape in the existing technology can not meet these environmental requirements.
