For the same tape, if the molecular weight or molecular weight distribution is different, if the composition of the same tape is different, the processing properties of the tape and the mechanical properties and physical and chemical properties after film formation will be different. This prompts us to pay attention to the grade and grade of the polymer when selecting the raw material of 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 effect on the properties of the film.
In the production of tape, polymers and certain additives are often mixed in a certain ratio to achieve the purpose of improving certain aspects of performance.
The influence of tape raw materials on tape
1. Polyethylene can be added to the lubricant as a raw material for the tape to improve the smoothness of the tape.
2. When preparing a film from polyethylene, it is necessary to add a stabilizer because of its easy thermal decomposition.
3, the tape must have a reasonable formula combination, the raw material of the tape in the formula should have a suitable ratio. Adjusting the composition and ratio can change the performance of the tape.
