In plastic products, fluorescent pigments can spontaneously fluoresce under visible light. They can give PP, PE and other plastics bright fluorescent colors and be used for optical identification, luminous identification, etc. According to the different carriers and processing temperatures, fluorescent pigments can be divided into high-temperature types (such as FQ series), low-temperature types (such as AX series) and water-based thermosetting types (such as FV series) to meet the process requirements of extrusion, injection molding, blow molding, film blowing and wire drawing. Among them, the FQ series has no formaldehyde emissions and does not stick to the mold, making it easy to clean.
By reasonably selecting the fluorescent pigment series, controlling the processing temperature and the amount of addition, the high brightness and lasting fluorescent effect of plastic products can be achieved, meeting the application requirements of toys, films, cables, optical identification and other fields.
Below, I will use simple examples to help you quickly grasp the classification, characteristics, application skills and purchase tips of fluorescent pigments, so that you can understand them at a glance and use them immediately!
Series and classification:
- 1.AX series (low temperature thermoplastic type): It is a thermoplastic fluorescent resin pigment, suitable for 120-190℃ low temperature process, and is recommended for extrusion, injection molding and film blowing of plastics such as PP, PE and PVC.
- 2.FQ series (formaldehyde-free melting type): Fluorescent pigment with thermoplastic resin as carrier. It has good fluorescence intensity and dispersion performance, does not contain formaldehyde, heavy metals and 24 banned aromatic amines, and is particularly suitable for coloring high-temperature plastics. The minimum processing temperature is 160℃ and the maximum can reach 260℃. It is mainly used for extrusion, injection molding, blow molding and film blowing of various plastics and masterbatches, such as PP, PE, etc.
- 3.FZ series (formaldehyde-free melting type): It does not contain formaldehyde, heavy metals and 24 banned aromatic amines, and is particularly suitable for coloring medium and high temperature plastics. It is used for extrusion, injection molding, blow molding and film blowing of various plastics and masterbatches, such as PP, PE, etc. It can reach up to 240℃, and is recommended for masterbatches, film blowing and wire drawing.
- 4.FV series (high temperature thermosetting type): thermosetting fluorescent resin pigment, high temperature resistance, migration resistance, solvent resistance, heat resistance up to 240℃, suitable for water-based systems and plastic surface spraying.
Functions of fluorescent pigments in plastics:
- Ultra-high color rendering power: less dosage than ordinary pigments, but several times brighter, saving materials and looking good.
- High temperature resistance: many series have decomposition points above 200℃, and they are not sticky during processing.
- Easy to mix: it does not stick to the screw when mixed in the resin, and it does not grow "lumps" when making masterbatch, and the color distribution is more uniform.
Application process and recommendation:
- Extrusion:
In the extrusion process, fluorescent pigments need to withstand shear force and high temperature. Both AH series and CZ series are suitable for the preparation of PP and PE extrusion masterbatch. The recommended addition amount is usually 0.1%~1% (w/w), which can be fine-tuned according to color requirements.
2 Injection molding:
Injection molding has high requirements for fluidity. Due to the low melting point characteristics, the AL series and K series can achieve efficient dispersion and high color intensity coloring in the range of 135℃～190℃, and do not stick to the mold.
3 Blow molding and film blowing:
The process temperature of blow molding and film blowing is 160℃～220℃. It is recommended to use AH series, AL series and CZ series fluorescent pigments to ensure excellent stretchability and film transparency while maintaining high brightness fluorescence.
4 Wire drawing (fiber and wire):
In the wire drawing process, the AFQ series fluorescent pigments are specially designed for masterbatch coloring and plastic wire drawing. They can maintain uniform dispersion and stable color at high stretching rates. They are suitable for PP, PE fibers and PET wires.
5 Masterbatch preparation and use:
Masterbatch is a coloring aggregate in which a large amount of fluorescent pigment is pre-dispersed in a carrier resin. The use ratio is generally about 1:50. It is widely used in films, cables, sheets, pipes and synthetic fibers. It can simplify the production process and improve dispersion.
Purchase suggestions:
Brand and quality: Choose products with complete thermal stability, light stability and formaldehyde-free emission certification, such as FQ series, FZ series, CZ series, etc.; high-temperature types are slightly more expensive and have more functions; low-temperature types are cheaper and save electricity; give priority to suppliers who can provide sample testing and fast technical support, which can save a lot of debugging time.
