Established in 2002, Hangzhou Yeming Science&Technology Co., Ltd specialized in the research&development, manufacture and marketing of new-type photoluminescent materials. The company is a high-tech enterprise based on modern management pattern and standardized operation. As one of the biggest factorys that produce photoluminescent pigments and photoluminescent products in China, We can develop, manufacture and test independently. And we also have close cooperations with Laboratory of Zhejiang University. In the recent years, the company increased rapidly in size, now the number of the people exceed 100 and the number of offices reached 7. Our photoluminescent pigments cover in all particle sizes and all emitting colors. The luminance and after-glow time of our factory are excellent.

Our photoluminescent finished products are made with our own photoluminescent pigments, so their luminance and after-glow time are also excellent, they exceed the the European standards significantly. Therefore, our photoluminescent products are usually exported to Denmark, Spain, UK, Portugal, Australia, USA, Brazil, South Korea, Mexico, Japan and so on.

A. Long after-glow time photoluminescent pigments based on different colors and particle sizes;
B. Photoluminescent signs based on materials, for example aluminum, stainless steel, PVC, etc.
C. Other photoluminescent products, for example: Photoluminescent rigid PVC plates, photoluminescent films, photoluminescent stripes, photoluminescent tiles, photoluminescent tapes. Photoluminescent and others;

A. Digital Phosphorophotometric System: Used for testing the luminance of photoluminescent pigments;
B. Powder particle-size analyzer: Used for testing the particle size of Photoluminescent pigments;
C. UV illumination meter: Used for observing the luminance of photoluminescent materials and photoluminescent products;
D. Spot luminance meter: Used for testing the luminance of photoluminescent products;
E. High-altitude collision device;

4. Yearly capacity of our main products:
A. Photoluminescent pigment: 120 tons;
B. Photoluminescent signs including the aluminum signs, PVC signs and other signs: 25000 square meters;

1. The characteristics of our products:
A. Absorbing light capacity of our high-brightness photoluminescent pigments are extra-strong, they can absorb the light under 25lux fast;
B. The highest brightness of our high-brightness photoluminescent pigments can reach 35000mcd/m2 after 5 seconds and the after-glow time can last 40 hours;
C. We can produce the ultra-fine photoluminescent pigments(the average particle size smaller than 7um) and the monthly capacity is 2 tons;
D. We can produce the high brightness photoluminescent signs, and their brightness exceed the PSPA standard significantly. For example, the luminance of our highest brightness aluminum signs can reach 105mcd/m2 after 60mins when tested according to DIN 67510 Part 1.

6. Production equipments:
A. 2 over-long electrical ovens with four-path and two-way, and we are going to increase another one at the end of November due to the increased demand of our pigments;
B. Several breaking plants, 2 airspeed stripping apparatus, 10 ball milling apparatus, 4 classifying equipoments;
C. 2 mixing plants;
D. Several drying machines
E. 2 spraying equipments
