fluorescent pigment for PVC | Wanlong

1. What is PVC material? Why is fluorescent pigment used?

PVC is a very common and widely used plastic material with the following advantages:
Low cost;
Good mechanical properties;
Easy to process;
Can be made into soft or hard products.
Water-resistant, acid-resistant, alkali-resistant, and oil-resistant;
It can be used for a long and is not easy to age.
These characteristics make PVC widely used in wire sheathing, floor leather, pipes, advertising materials, toys, stationery and other fields.
Fluorescent pigments can make PVC products more eye-catching. For example, fluorescent wires, pipes or signs can be quickly found in the dark or foggy days, greatly improving safety.

Fluorescent pigment for pvp

FN series fluorescent pigments are specially used in transparent PVC products. Their biggest feature is transparency. Compared with ordinary fluorescent dyes, their physical properties are better, such as being more stable and less prone to deformation.
It is a thermoplastic fluorescent pigment- it can soften after heating and harden after cooling, which is very suitable for making various plastic products. Its color is very bright and vivid, and it does not require a lot of dosage to achieve a good coloring effect. It has a high concentration and strong color saturation.
FN series fluorescent pigments have several advantages:
Good heat resistance, not easy to change color at high temperatures.
It disperses well when coloring and will not clump.
It is also very transparent;

FN series pigments are very suitable for coloring transparent PVC films, such as some packaging films or plastic bags we usually see. It can also be used in the production of various PVC plastic products such as calendering, extrusion, injection molding, etc.
Recommendation on the amount of fluorescent powder added. In opaque plastics, no matter how much fluorescent pigment is used, only the surface layer fluorescence is produced. Fluorescent pigments are applied to pure, transparent plastics to produce the brightest colors. The correspondence between the pigment concentration required to achieve the fluorescent effect and the thickness of the transparent plastic sheet is roughly as follows:

How to apply fluorescent pigments to PVC?

There are roughly the following ways to add fluorescent pigments to PVC:
1. Dry Blending
Mix the fluorescent pigment directly with the PVC powder and then extrude or inject it. This method is simple, but the dispersion effect is average, and it is suitable for occasions where the appearance requirements are not high.
2. Masterbatch method
The fluorescent pigment is first made into concentrated masterbatch, and then mixed with PVC substrate for processing. This method has good dispersibility, uniform color, and convenient operation. It is one of the most commonly used methods.
3. Coating method
Coating a coating or ink containing fluorescent pigment on the surface of the molded PVC. It is suitable for soft or thin film PVC products, such as advertising films.
4. Dipping method
For some PVC coating materials, fluorescent pigments can be adsorbed on the surface by dipping, which is suitable for temporary use.
