TPE? Children's waterproof bibs, headphone cables, data cables, toothbrush handles and other products produced using TPE\TPR will have different patterns or manufacturer logos on them. Some friends will ask if the TPE \TPR material surface printing is easy to fall off? The pictures on the surface of TPE material are mainly produced through two printing processes: silk screen printing and laser engraving.
Regarding TPE\TPR material printing processing, there are certain requirements for the required materials and additives. It is necessary to adjust or select appropriate TPE\TPR materials and supporting additives.
The printing principles of silk screen printing and laser engraving are different. Screen printing is mainly through -well plate , and the ink is transmitted to the printing object through the grid of the image part, forming the same pattern and text as the original pattern. Radium engraving is also called laser engraving. The TPE and TPR materials used in laser engraving should be specially modified to make the material have laser engraving characteristics. The principle of laser engraving marks the chemical and physical changes of the laser beam's light energy to the surface material, forming marks. The adhesion of printing on the surface of TPE\TPR materials is discussed below.
Use silk screen printing or printing mode mode. It should be noted that the ink used for silk screen printing has good compatibility with TPE\TPR materials (according to the principle of chemical similarity, the materials have close polarity, easy to dissolve or compatible with each other) to ensure the adhesion of the ink and TPE\TPR materials. TPE, TPR is a hybrid material with different TPE\TPR grades, and the composite components contain different substrates and reinforced plastics.
thermoplastic elastomer TPE\TPR should vary according to the material formulation system. The key to ink selection is the solvent part, which is related to the adhesion of the screen printing. For example, the TPR of the SBS + PS system should usually choose inks containing acrylate , toluene and xylene solvents, while the TPE of the SEBS + PS system is much more difficult than wire printing, and chloroform or carbon tetrachloride is usually used. The solution is to pre-surface and then attach the print with appropriate ink. Electric silk printing is generally used in toys and crafts TPE and TPR products, and most of them are in printing mode.
Lientpe manufacturer finally talks about laser engraving. Just adjust the TPE\TPR material composite system appropriately. laser beam can undergo chemical and physical changes, and can engrave the corresponding color text. The main TPE, TPR material has been properly modified and the text radial engraving will be very good and will not fall off. Radium engraving printing is currently mainly used for cables, plugs and electronic components. How to improve the printing and shedding of
TPE material? When we sell thermoplastic elastomer TPE\TPR materials, customers often ask questions such as whether your materials can be printed and whether they will fall off. If your product requires printing, you must inform the TPE manufacturer before the sample. This can be improved through the formula system. After so many years of development in TPE materials, many functional requirements can be fully solved.
