Chengdu Donglanxing Science & Technology Development Co.,Ltd. is a new-and high-tech enterprise engaging in developing ,producing, and marketing the concrete, mortar cracking-proof polypropylene, synthetic fiber, asphalt concrete reinforced synthetic fiber, especially silica fume(microsilica fume).
　　
Our company has many experts and professors in charge of producing the project fiber and collecting silica fume. For ensuring the quality of our products, we have strengthened the cooperation with famous building material academies and universities. Even, our company has built consummate quality-testing equipments.

Our company has its own silica fume base, and the annual capacity of producing is up to 10000 tons. The EBS- silica fume has high content of SiO2, and its indexes are very excellent. So far, the company has developed special silica fume for fire-proof materials, and its SiO2 content is above 94%, usually up to 97%, which has reached the first-level national standard. EBS- silica fume is widely used in water-conservancy hydraulic power project, civil architecture, bridge, fire-proof material, cement prefabricated element, paint, rubber, etc. Because of its good quality, the silica fume has been exported to Germany, India, Korea, and so on.

Our products, EBS-P polypropylene fiber, EBS-B polyester fiber, in its quality and application performance are up to /over that of the imported products. EBS-P polypropylene fiber mixed into cement concrete and EBS-B polyester fiber into asphalt concrete can improve the complex performance of the concrete, prolong its service life, and reach the goal to build up high-quality concrete project. The reliability and cost performance of our products bring wide users and construction projects which also bring us not only large economical benefit but social benefit. So far, our products have been applied to water-conservancy hydraulic power project, tunnel, dam, railway, highway, bridge, swimming pool, civil architecture, etc.

Taking “developing the new products by scientific research, forging the choice by technology and promoting the development by science” as our developmental concept and going along with the development road of “famous, special, top and novel” products, our company bases on technology to offer top products and service for our client . Please believe us that we are the best one in this field.
