Tape is very common in our daily life and work, then for the tape factory to produce tape raw materials, many people should not quite understand, following with Anhui Hefei New Era Tape Factory Xiaobian to see.
For the same tape, if its molecular weight or molecular weight distribution is different, if the composition of the same adhesive tape is different, the processing performance of the tape and the mechanical properties, physical and chemical properties, etc. after the film is made will be different. This prompts us to pay attention to the grade and grade of the polymer when selecting raw materials for the tape. In the production of plastic films, it is often necessary to add some additives to the polymer, and the type and properties of these additives have a significant impact on the performance of the film.
In the production of adhesive tapes, polymers and certain additives are often mixed at a certain ratio to achieve the purpose of improving certain aspects of performance.
Tape raw materials influence on the tape
1. Polyethylene can be added to lubricants such as tape raw materials to improve the smoothness of the tape.
2. In the preparation of polyethylene films, stabilizers must be added because they are prone to thermal decomposition.
3, tape must have a reasonable formula composition, the tape raw material in the formula should have a suitable proportion. Adjusting the composition and proportions can change the properties of the tape.
