The transparency of screen printing silicone is determined by a variety of factors, mainly including the following aspects:
Raw material purity: The purity of the raw material of silicone is a key factor affecting transparency. The higher the purity of the silicone, the less impurities it has inside, and the less light is scattered and absorbed when passing through, thus showing higher transparency. Therefore, when selecting screen printing silicone, the purity of the raw material is an important consideration.
Production process: The refinement of the production process will also affect the transparency of screen printing silicone. During the manufacturing process, factors such as temperature control, stirring uniformity, and vulcanization time will affect the microstructure of silicone, which in turn affects its transparency. Fine production processes help reduce defects inside silicone and improve its transparency.
Additives: In order to improve certain properties of silicone, such as hardness and color, some additives or pigments may be added during the production process. The type and amount of these additives will affect the transparency of silicone. Especially for color additives, the darker the color, the lower the transparency of silicone. Therefore, in the production process of screen printing silicone, the type and amount of additives need to be strictly controlled to ensure the transparency of the product.
Mold surface brightness: The brightness of the mold surface will also affect the transparency of silicone products. When the mold surface is very bright, the silicone molded products will be more transparent. Conversely, if the mold surface is rough or dull, the transparency of the silicone products will also decrease accordingly. Therefore, in the production process of silk-screen silicone, it is necessary to select a mold with high surface brightness to improve the transparency of the product.
In summary, the transparency of silk-screen silicone is determined by a variety of factors such as raw material purity, production process, additives, and mold surface brightness. In order to obtain silk-screen silicone products with high transparency, it is necessary to comprehensively consider and optimize raw material selection, production process control, additive use, and mold selection
