The main application areas:
LB series of fluorescent pigment is the most widely used in various types of polyolefins, polyvinyl chloride film or coating, including various types of coloring plastics field. To sum up, its main application areas including plastic anti-stick roller shading system, and seepage analysis of the vinyl plastisol system.
Product performance:
LB series of fluorescent pigments by small, opaque micro-shaped particles, with excellent anti-stick roller performance. Its strong coloring, color, concentrated and purified. The impermeability of the analysis of performance makes it particularly suitable for a variety of vinyl plastic, in the plastisol.
The main technical indicators:
| Proportion | Average particle size | Hagemeyer granularity | Softening point | The maximum processing temperature |
| 1.3 | 3-5um | 6.8 | ～275℃ | ～260℃ |
Application characteristics in the field of plastics coloring:
A.Non-stick rollers: when dealing with a fluorescent dye in the plastic processing tend to have sticky roll phenomenon. The phenomenon of the so-called sticky roller, low molecular weight organic compounds (such as oligomers, fluorescent dye) in the thermal decomposition process mixed, and separated from the plastic mixture, deposited on the screw, blow molded mouth and other metal equipment.LB series of fluorescent pigments in many cases to rule out the occurrence of sticky roller.LB series of fluorescent pigments, often simply rinse with clean material, and therefore greatly reduce downtime, improve work efficiency.
The processing temperature: LB series is recommended for up to 260 ° C plastics processing.And other fused fluorescent pigment, small spherical particles in the LB series of fluorescent pigments in the process does not change, so they need higher shear to disperse the pigment in order to achieve the best color.Add a small amount of ZnO (5%) of the amount of fluorescent pigments to increase the thermal stability of the LB series, but the yellow and green, except for Zn make contain any of the compounds of the above two colors to produce color migration.
Processing aids:LB series can easily be used in many plastics coloring process conditions without dispersing aids. Such as processing aids must be used, you should avoid the use of zinc additives in the green yellow and green pigments (for example: calcium stearate instead of zinc stearate). See "Note
