This article discusses how to incorporate fluorescent pigments into plastic masterbatch to enhance the visual appeal of your plastic products.
1. What is fluorescent pigment?
Fluorescent pigments do not emit light by themselves. Its principle is: absorb sunlight (especially ultraviolet rays) → then emit super bright color light. So it can also appear particularly bright during the day or under light.Compared with ordinary pigments, they have the following advantages:
The colors are brighter and more "bright";
They are very eye-catching from a distance and have a high degree of recognition.
They can make the product look more fashionable and more technological.
Therefore, whether it is a trendy brand, a toy, stationery, or a traffic warning product, fluorescent pigments are very popular.
2. Which plastics can fluorescent pigments be added to?
Although fluorescent pigments are widely used, not all plastics are suitable for adding them. Because it is afraid of high temperatures, it can generally only be used within 200°C. So these plastics are most suitable for:Plastic types: Common scenarios
PP (polypropylene) Stationery, daily necessities, small toys
PE (polyethylene) Plastic bags, flexible packaging, children's products
PVC (polyvinyl chloride) Soles, wires, transportation supplies
PS, EVA, ABS, etc. Toys, trendy accessories, foam
3. How to make fluorescent pigments into masterbatches? (Practical steps)
If you want to make fluorescent pigments convenient to use, you must first make them into "masterbatches" - just like seasoning packets, just add them directly to the plastic when using them.Step 1: Select materials
Choose a resin that is compatible with your plastic as a carrier, such as PP products, and use PP as the base material.
Choose fluorescent powder suitable for plastics, which should be environmentally friendly, heat-resistant, colorful and will not fade.
Step 2: Dry mixing (stirring premixing)
Mix the pigment powder, resin particles, dispersant, etc., and mix them well like mixing cake flour. The ratio is roughly:
Fluorescent powder: 10~30%;
Plastic base material: 60~80%;
Dispersant/lubricant: 1~5%;
The more evenly the stirring is done, the more stable the color of the masterbatch produced later will be.
Step 3: Extrusion granulation
Use a twin-screw or single-screw extruder to extrude the mixed raw materials into strips, and then cut them into small particles.
Pay attention to the temperature! The processing temperature should not exceed 200°C to prevent the fluorescent pigment from changing color.
Step 4: Test the finished product
See if the color is bright.
See if the distribution is even.
Make an injection molded part test to see the actual color effect and fastness.
4. What are the uses of fluorescent masterbatch? (Revealing the practical scenarios)
1. Toys, stationery, small ornaments (PP, PE)These products are most commonly added with fluorescent orange, fluorescent green, and fluorescent powder, such as:
Fluorescent pen caps;
Fluorescent cars, mini building blocks;
Fluorescent storage boxes, mobile phone case pendants.
Recommended proportion of masterbatch: 1%~3%, the color is already very conspicuous.
2. Packaging film (PE blown film)
On cosmetic packaging, fluorescent film looks super good. For example, fluorescent pink facial cleanser packaging.
Adding about 2% of masterbatch can significantly enhance the "high-end feel".
3. Safety products, traffic signs (PVC)
This type of product is most concerned with "being visible from a distance", so fluorescent pigments are used a lot.
Fluorescent orange traffic cones;
Fluorescent yellow night running armbands;
Fluorescent green wire skin.
It is recommended to use a high light-resistant version of fluorescent powder, adding about 3% will have a good effect.
