Products Description
N339 is a new process high structure wear-resistant furnace black, which is especially applied for the blend system of styrene butadiene rubber and cis-1,4-polybutadiene rubber. While producing tire tread compound, carbon black n339 is similar to N220 in reinforcement, wear and cracking resistancw. It is manily used for passenger tires, truck tread rubber, conveyor belts, rubber hoses and various rubber industrial products with high abrasion with high abrasion resistance requirements.
Product Application
N339 carbon black particle size is moderate, the surface wettability is good, can effectively improve the processing property and tear strength of rubber products. N339 carbon black also has high groove wear resistance and permeability resistance, which can effectively improve the durability and service life of plastic products.
N339 carbon black is also widely used in asphalt pavement and coatings. The addition of carbon black n339 can increase the shear resistance and aging resistance of asphalt pavement, and improve the durability and stability of pavement. At the same time, adding carbon black to the coating can improve the UV resistance and weather resistance of the coating, so that the coating has a longer protection effect.
