The main products is carbon black series:N220、N234、N326、N330、N339、N375、N539、N550、N660 etc.We can produce special carbon black according to user requirements.The carbon black N220 is used in rubber,The wear resistance is 10%-20% high than N330,using N220 the rubber can get more high tensile strength and slitting-sesistant strength and it has a certain degree degree of electrical conductivity.It mainly used for truck tyres,passenger tire tread compound and the need for high-intensity,high wear-resistant rubber products.The wear resistance of N234 is 10%-20% high than N220,in high strength,it is good wear resistance than the N220,it mainly used for high-speed tread rubber and high-quality rubber products.The N326 carbon black has high tensile strength,slitting-resistant strength,wear resistance and anti-bouncing cracking performance in natural rubber,it mainly used for high-strength,low-heat tyres,it also used to conveyors,sealing products and high quality rubber products.N330 is a good reinforcement carbon black,with it the rubber can get better strength,elongation properties,slitting-resistant properties,wear resistance and flexibility.It mainly used in tire tread,plastic cord,rubber tire side and other rubber products. The N339 carbon black is tread compound reinforcement properties,similar N220,especially used for butadiene styrene-butadiene rubber and plastic,it mainly used for passenger tyres,tread rubber tyres card,conveyors,Hose and high wear-resistance requirements of industrial rubber products.N375 and N339 are basically the same performance,heat slightly lower than the N339,it mainly used cars births,fetal and cross-country truck fetal tread compound.
