Carbon Black N326 is a high-performance, furnace-grade carbon black widely used in the rubber and tire industries. Known for its low structure, excellent tensile strength, and good elongation at break, N326 provides unique physical and chemical properties that make it an ideal choice for demanding mechanical applications.
As a type of High Abrasion Furnace Black (HAF), Carbon Black N326 delivers better tensile stretch than many other grades while maintaining moderate stress at definite elongation. This makes it a preferred reinforcing filler for rubber compounds that require a balance between strength, flexibility, and durability.
Applications of Carbon Black N326
This product is used across multiple sectors, with its primary application in rubber manufacturing. Some of the most common uses include:
Tire Carcasses: N326 enhances the durability and structural integrity of tire bodies, making it suitable for heavy-duty and high-performance tires.
Off-the-Road (OTR) Treads: Its abrasion resistance and tensile strength make it suitable for the rugged treads used in OTR and industrial vehicles.
Belts and Conveyor Belts: N326 is used in rubber belts to ensure they retain their flexibility while resisting cracking under stress.
Rubber Seals and Gaskets: The flexibility and chemical stability of Carbon Black N326 make it an excellent filler for sealing materials.
General Mechanical Rubber Goods (MRG): From hoses to vibration dampers, N326 is ideal for various mechanical components requiring strength and wear resistance.
Physical Characteristics
Carbon Black N326 appears as a black, amorphous, granular or beaded solid. It is produced through the furnace black process, resulting in hard particles that offer uniformity and consistency in applications.
