PL series photoluminescent pigment
PL series photoluminescent pigment is alkaline earth aluminate photoluminescent material.
It has been exported to many countries and regions. These products can glow more than 12 hours after absorbing various visible light or ultraviolet radiation. The luminance is 350-700mcd/m2 and afterglow is more than 12 hours. PL series photoluminescent pigment includes PLO, PLB and PLP type. The physical properties are as tabled below:
⑴ The unit of particle size is μm. The particle size is expressed by Medium Particle size (D50).
⑵ The unit of afterglow brightness is mcd/m2. All the tests are executed according to the standard of DIN67510, which is to detect afterglow brightness of the sample for 10 min excited by D65 standard light source illumination of 1000LX for 5 min.
