Sino-roc Colors International is a hi-tech enterprise, dedicating to develop photoluminescent pigment, reflective pigment in nanometer technology, utilizing the self owned capital, technology, management and selling network, and cooperating with domestic and overseas famous university and scientific research institutes, we have established and industrialized entity with production, research and development and sales of hi-tech products.

From the establishment, we always hold that we shall develop our company by developing a knockout product, starting up a market, bring along a company group, and developing an industry. On the way of technology and management innovation to develop the key industry supported by the state, tsinghua rainbow aggressively develop products with high technology content and high additional value. Transfer powder PDP(plasma display panel) Dedicated phosphor powder and nanometer A1203 etc. Superlong afterglow oxide nanometer luminescent material features high brightness, lasting afterglow, nontoxic, non-radioactivity etc. It is a perfect green light source, especially applicable to material appliance, and emergency evacuation system. And it is also an energy saving material to efficiently utilized light and electric energy. Furthermore. Its matrix material has good chemical stability, it can mixed with various kinds of substances, through second-time development, it can be widely used in industries like textile, construction material and printing etc.

Climate-proof rare optical transfer powder is a kind of new agricultural film additive. Adding a certain proportion of this powder to polyethylene resin can produce agricultural shed optical transfer film. The film can transfer ultraviolet and green light in sunlight not required for plant growth to necessary red and blue light, consequently facilitate plant photosynthesis and achieve the goal of increasing crop production and earlier production. It shows very obvious social and economic benefit.

Plasma display panel technology and material support i becoming more important, especially key material of display, PDP display phosphor powder bears the brunt. Rare earth nanometer powder with high efficiency, good stability and good color matching will of a certainty to be mainstream of market. Looking into the future, We will move to the global hi-tech field, and to create bright future with our aggressiveness.

We are developing, manufacturing and exporting photoluminescent pigment in colors, yellowgreen, yellow, green, aqua blue, skyblue, purple, orange, red and bluegreen can be in white powder color, together with its downstream products, like PVC luminous film, signs for subway, also manufacture reflective pigment and PDP powder.
