  In the process of using adhesive tape, a common problem is non-stickiness. According to analysis of relevant persons, the main reasons for this phenomenon are the following:
  1. Oxygen: Because the content of oxygen in the air accounts for 21%, and oxygen has the property of accelerating the oxidation of substances, its activity is very heavy, which causes rapid oxidation of the tape, resulting in the tape becoming non-sticky.
  2. Ultraviolet rays: Ultraviolet rays have high-temperature characteristics and can quickly decompose sticky substances. Tapes that have been exposed to sunlight for a long time will be decomposed by them, causing the tape to age.
  3. Metals: Especially brass or rust. In the daily life, any organic matter and substance can react with metals, especially brass or rust. The tape contains organic compounds, which leads to tape aging.
  4. Bleaching agent: Its main component is calcium oxide, which contains calcium element and can react with organic compounds to cause aging of the tape.
  5. Plasticizer: Its main function is to soften plastics. Most plastic products contain plasticizers. With the change of time, the proportion of plasticizers in the material itself will increase, which will cause the aging of the tape.
