It is a high-quality variety of carbon materials, its appearance is a silver-gray porous solid particles with metallic luster, its structure has obvious flow texture, the holes are large and few and slightly elliptical, the particles have a large aspect ratio, like fibrous or needle-like texture trend, touch has a sense of lubrication,It is the raw material for producing high-end carbon products such as ultra-high power electrode, special carbon material, carbon fiber and its composite material.Yuai's needle coke is also the domestic authorized agent of many world top 500 enterprises from Korea, Japan and so on. The products are first-hand, the quality is stable and the price is very competitive.

It is a kind of easy graphitized carbon material with low sulfur and ash. It is a product obtained by direct coking of coal pitch in coke oven as raw material, and can also be produced by delayed coking method. Compact structure, high mechanical strength and wear resistance of particles. It is widely used in lithium battery anode materials, special carbon materials and other industries. Shanghai Yuai is one of the earliest manufacturers of asphalt coke projects in China, and has long-term cooperation with many well-known manufacturers at home and abroad. It is the authorized agent of asphalt coke in Korea, Japan and other top 500 enterprises in the world, and has the competitive advantage of abundant resources, quality assurance and reasonable price.

It is the solid carbonaceous material obtained after the coking of petroleum residue and petroleum asphalt produced by petroleum processing. The main element is carbon and the ash content is very low, generally less than 0.5%. It is prepared by the refinery through delayed coking (500℃), containing a lot of volatile matter and low mechanical strength. The appearance of petroleum coke is a black or dark gray honeycomb structure, and the pores in the coke block are oval, which belongs to the easy graphitization of carbon. High performance petroleum coke, due to its high cost performance characteristics, is also widely used in lithium battery anode materials and graphitized electrodes and other industries. Shanghai Yuai has been engaged in the petroleum coke industry for many years, and owns high-quality petroleum coke resources such as CNOOC, Daqing and Fushun.
