N326Low structure high abrasion furnace black| Product
■N326（HAF－LS）Low structure high abrasion furnace black is one of N300 series of Round Star Company. N326 has low structure and high reinforcement with low heat. Plastic material with N326 has a high tensile strength, tear strength, abrasion resistance and anti-chunking performance, only the dispersion in the rubber compound more difficult. ■N326 is widely used and applicable to all kinds of tire side ply rubber, in the NR... -
N330High Abrasion Furnace Black| Product
■N330 (HAF) HAF is an early production of Round Star of the N300 series. In the N300 series products, N330 wear resistance is less than the N200 series products, but better than the black tank, passenger car tire with N330 rolling losses is more than just the same series N351, when compared to the same series of other varieties are less, while processing performance are also better. ■N330 is widely used for tire tread, sidewall... -
N339New technology high-structure super abrasion furnace black| Product
■N339（HAF－HSNT）New technology high-structure super abrasion furnace black is the main product of Round Star company within N300 series. N339 is better than N347 on wear resistance and anti-increase of breach, like N220. Rolling resistance of tire with N339 is the highest within N300 series, while its wearing resistance is the best. ■N339 is widely used and typical furnace black used for tire, applicable to car tire...
