Carbon Black N339 is one of the most reliable reinforcing grades used in the rubber, tire, and polymer industries. Because it offers strong reinforcement, clean dispersion, and high abrasion resistance, manufacturers across the world choose it for demanding applications. As a result, N339 has become a trusted option for companies that need durable and flexible rubber products. Additionally, this grade maintains stable performance, which makes it ideal for long production cycles and heavy-duty environments.
Since N339 belongs to the hard-grade furnace black family, it supports products that must handle repeated movement, high stress, and extended service life. Therefore, producers in automotive, construction, plastics, and industrial sectors rely on Carbon Black N339 as a safe and stable solution. At the same time, Basekim supplies premium-quality N339 that meets international standards and delivers consistent results in every batch.
Carbon Black N339 stands out because it combines hardness, elasticity, and processing ease in one grade. While many grades focus on either wear resistance or flexibility, N339 provides a balanced performance profile. Consequently, manufacturers can use it in both dynamic and static rubber applications. Moreover, its clean dispersion helps factories achieve uniform mixing in shorter processing times.
Key advantages include:
High abrasion resistance, which extends product life
Excellent reinforcement, which increases tensile strength and elasticity
Fast processing, which reduces mixing energy
Low hysteresis, which lowers heat build-up in tires
Wide application range, which fits automotive and industrial uses
Stable quality, which ensures predictable production results
Because of these benefits, Carbon Black N339 is an ideal grade for companies that want dependable mechanical performance.
The following specifications explain why this grade performs reliably across different industries:
| Property | Value |
|---|---|
| Iodine Absorption | ~82 mg/g |
| DBP Absorption | ~114 cc/100g |
| Surface Area (BET) | ~77 m²/g |
| Tint Strength (ASTM) | ~121% |
| Structure | Medium |
| Particle Size | ~26 nm |
| Heat Loss | ≤ 1.0% |
| Ash Content | ≤ 0.5% |
Altogether, these values demonstrate N339’s ability to support high tensile strength, tear resistance, and long wear life. In fact, its structural balance makes it suitable for many formulations.
Although N339 is widely used in the tire industry, it also plays a major role in several other industrial sectors. Because it reinforces rubber and reduces surface wear, companies use it in products that must endure continuous stress.
1. Tire IndustryManufacturers use N339 in tire tread compounds, since it delivers long wear life, improved grip, and reduced rolling resistance.
2. Belts and HosesIndustrial belts and hoses need elasticity and strength. Therefore, N339 helps prevent cracking and deformation under pressure.
3. Rubber MoldingSeals, gaskets, vibration parts, and automotive components benefit from N339’s tensile reinforcement. As a result, molded parts maintain shape and flexibility for longer periods.
4. Plastics and PolymersWhen added to plastics, N339 improves conductivity and anti-static behavior. Furthermore, it enhances surface uniformity.
5. Industrial RollersBecause rollers face heavy friction, N339 helps extend service life and maintain consistent performance.
6. Footwear SolesN339 supports flexibility and durability in soles. Thus, the final product stays strong without becoming brittle.
Overall, this grade is extremely versatile across multiple industries.
Manufacturers often compare grades before choosing the right material. Compared with other furnace blacks, N339 offers a better mix of strength, wear resistance, and processing speed.
N339 vs. N220: N339 provides cleaner dispersion and easier processing.
N339 vs. N330: N339 offers higher wear resistance and improved durability.
N339 vs. N660: N339 delivers much higher reinforcement and tensile strength.
N339 vs. Soft Grades: N339 maintains flexibility while offering superior hardness.
Therefore, N339 becomes a preferred choice when manufacturers want strong reinforcement without losing flexibility.
Carbon Black N339 not only improves product performance but also supports smooth production workflows. Because of its clean dispersion, factories can reduce mixing times and energy usage. In addition, the grade helps maintain uniformity in every batch, which lowers waste and improves consistency. As a result, production efficiency increases across different manufacturing lines.
