Glow In The Dark Powder Mixed With Plastic
Glow in the dark powder can be mixed with various transparent or semi-transparent plastic materials such as PP, PE, PET, PVC, ABS, PLA, PS, AS, and Surlyn resin to create a range of luminous plastic products. Examples include glowing cups and tableware, glowing toys and sports equipment, luminous parts or accessories, glow masterbatches, and wires. Glow powder is non-toxic, environmentally friendly, and radiation-free. Products made with it can pass various safety tests.
- A special glow powder for injection molding has been developed. Compared to ordinary glow powder, it is less likely to turn black during use.
- The mixing speed should be as low as possible. Manual mixing is best. If using a mixing machine, the speed should be reduced and it should not be run continuously, only in short bursts.
- It is recommended to use an injection molding machine with a small hopper. If the hopper is too large, the glow powder can easily settle at the bottom, making it hard to mix evenly.
- If using glow masterbatch, the plastic raw material should preferably be in granular form. If using glow powder, the plastic raw material should preferably be in powder form. When both are of similar shapes, they mix more easily, and the dispersion of the glow powder in the final product will be better.
- It is best to use a small-diameter extruder to minimize residence time. Extruders with large inner wall areas or complex screw shapes often cause the final product to darken.
- Glow pigments come in different particle sizes. When using glow pigments in the extrusion process, the particle size should be chosen based on the size of the extruder nozzle.
- Various glowing plastic products can be made through extrusion molding, such as glow-in-the-dark 3D filaments, glow masterbatch, and other tubes and films.
- When using the blow molding process to produce thin-walled products such as straws and cups, it is recommended to use ultra-fine luminescent powder to ensure transparency and aesthetic appeal. Ultra-fine luminescent powder has smaller particle sizes, which can disperse evenly in the plastic, avoiding particle aggregation and thus maintaining the product’s transparency.
- The ratio of luminescent powder added to the plastic should be controlled within 15%. Exceeding this ratio can cause the product to darken and affect its appearance. It is recommended to conduct small-scale tests during production to determine the optimal addition ratio, ensuring the product has both good luminescent effects and aesthetic appeal.
- Choosing luminescent powder certified for food safety is crucial. GlowUp® brand luminescent powder can pass food safety tests in end products, ensuring they are safe for human use.
