rubber raw material

1.Supply carbon black N220 ,wet granular and power
2.carbon black N220: high quality and competitive price
carbon black N220 is suitable for all kinds of rubber.Its wearability is higher 20%-30% than N330 and it has some conductivity.carbon black N220 is usually used in radial truck , passenger tire and rubber products needing high strength and high wear resistance.
We mainly produce and sell carbon black N220,N330,N550,N660,N326,N774 ect.We also can produce new products according to your needs.Our carbon black include wet granules and dry powder.The 100% of our products are surperior grades.The test index can be seen on our web.
Our company has 2 product line of U.S. Cabot and 1 automatic inspection line.We have 6 professional technical personnel,who have worked in carbon black for more than 20 years.Our products are exported to South America,European Union and South-Eastern Asia ect.
Our products have 3 competitive advantages.
1.The advantage of price.Our factory is located in the producing area of coal tar,and there are enough materials.So the transportion cost is low.And the price of our products is 10% lower than the others.
2. The advantage of raw material.Because we are located in the producing area of coal tar,so the cost of material is lower.
3. The factory is near away from Qingdao,and the distance of warehouse to Qingdao port is only 180 km.So we can delivery quickly.
