Everyglow Turquoise Photoluminescent sand LBB-S500
Turquoise Photoluminescent sand is a Rare earth strontium aluminate base glowing material, which have 30 times afterglow than traditional zinc sulfide base luminescent material. Everyglow LBB-S500 photoluminescent sand is from bigger particle size LBB series pigment, available glow more than 24 hours after absorb the visible light for 5-30mins, and this emit & absorb light process is repeatedly,no power request.
Products Properties:
- Free of radioactive elements , non-toxic, harmless, Eco-friendly material.
- Longer afterglow time and super higher luminance than traditional ZnC sulphur luminecent material.
- Excellent heat resistance . Good performace for temperature as high as 800℃
- Perfect light resistance. under 300W high pressure mercury lamp for 1000hr even not reduce them luminance.
- High chemicals stability. Everyglow Phosphorescent sand not reaction with any organic and inorganic agents except mercury.
- Long life time. as long as 30years life time.
