Manufacturers often need a reinforcing filler that improves strength without making rubber too stiff. That’s where carbon black N772 stands out. This semi-reinforcing grade balances flexibility, processing ease, and durability, especially in automotive and industrial rubber.
Unlike highly structured blacks, carbon black N772 allows better elasticity, longer life, and smoother mixing. Because of these qualities, it is widely used in tires, hoses, belts, and molded rubber parts. Moreover, it supports UV resistance and thermal stability, making it ideal for outdoor and heavy-duty applications.
To begin with, carbon black N772 has a low surface area and medium structure. These traits improve handling during compounding. Additionally, its structure offers moderate reinforcement without increasing hardness.

ToggleLet’s look at the main technical specifications:
Iodine number: ~27 mg/g
DBP absorption: ~90 cc/100g
Heat loss: <1.0%
Ash content: <0.5%
Production method: Furnace black process
Because of its controlled particle size, this grade ensures uniform dispersion during mixing, which saves time and energy in the production line.
Automotive Rubber
The tire industry relies on carbon black N772 for sidewalls, inner liners, and certain tread applications. Since these parts require a balance between stiffness and flexibility, N772 is an ideal choice. Notably, it reduces heat build-up and supports better flex fatigue resistance. As a result, it helps extend the overall life of tires.Industrial Rubber Products
Manufacturers often use this grade in:
Hoses and tubing
V-belts
Engine mounts
Rubber mats
Conveyor belts
Since these products must resist cracking and wear under pressure, carbon black N772 is a top choice. Furthermore, it helps maintain shape and elasticity over time.
Coatings and Sealants
Although primarily used in rubber, carbon black N772 appears in coatings for corrosion protection. For example, primer coatings for pipelines or metal structures may include it to improve weather resistance.
Plastic and Polymer Compounds
In some cases, this grade is also added to plastic masterbatches. It offers UV protection and basic reinforcement, especially in outdoor storage containers, HDPE pipes, or agricultural films.
Here’s why carbon black N772 continues to attract demand across industries:
Moderate reinforcement: Improves strength without reducing flexibility
Excellent dispersion: Lowers mixing time and improves uniformity
Chemical stability: Resists oils, fuels, and ozone exposure
Heat resistance: Ideal for environments with thermal cycling
Process-friendly: Compatible with most elastomers
Cost-effective: Offers strength without high material cost
As a result, it’s a smart option for cost-sensitive projects that still require performance and reliability.
It’s useful to compare carbon black N772 with other grades like N330 and N990. Each has its strengths. However, N772 offers the best mix of flexibility, durability, and processing ease.
Property | N772 | N330 | N990 |
---|---|---|---|
Reinforcement | Medium | High | Low |
Flexibility | High | Medium | Very High |
Dispersion | Easy | Moderate | Easy |
Tint strength | Moderate | High | Low |
Cost | Low | Medium | Low |
Therefore, if you need a filler that supports both elasticity and wear resistance, carbon black N772 is your ideal solution.
Even though carbon black N772 is stable and non-reactive, handling it properly ensures safety and product consistency. Always follow these tips:
Store in a cool, dry place
Use masks and gloves to avoid dust inhalation
Avoid moisture exposure
Rotate inventory regularly
