Reclaimed carbon black

◉ Product appearance  

Recycled carbon black (rCB): An eco-friendly carbon black produced through the anaerobic thermal decomposition of scrap tires, which can replace petroleum-based virgin carbon black for use in reinforcing and coloring plastics and rubbers.

◉ Production

Waste tire shredding → removal of steel fiber → high-temperature pyrolysis → grinding and purification → modified finished product.

◉ Key Features

Low carbon and environmentally friendly, capable of processing waste tires, with lower costs. It possesses reinforcing, wear-resistant, and coloring properties, offering high value for money and is suitable for mid-to-low-end and general-purpose rubber and plastic formulations.

◉ Direct Replacements: N330, N550, N660

Alternative reasons.

Particle size, specific surface area, are nearly identical.

The micro-particle size, specific surface area, and reinforcement, tensile strength, and wear resistance properties of the regenerated carbon black match those of the three types of general-purpose carbon blacks.

Structural compatibility with universal formulations.

The structure degree overlaps with the N330/N550/N660 range, and its blending and processing properties, as well as the fluidity of the rubber compound, are compatible with existing processes.

The application scenarios are highly overlapping.

These are compatible with a wide range of products, including tire treads, sidewalls, rubber hoses, adhesive tapes, shoe soles, black plastic molds, and rubber components.

The formulation is compatible and can be blended.

Partial blending substitution (10%–50%) is possible without requiring significant changes to the formulation or production equipment, resulting in cost reductions while still meeting quality standards.

◉ Product advantage

Waste material resource utilization, low-carbon emission reduction, compatibility with standard carbon black grades, significant cost reduction, and compliance with foreign trade environmental protection and dual-carbon policies.

◉ Product use

Tires, rubber accessories, rubber hoses and tapes, shoe soles, black masterbatch, plastic fillers, corrosion-resistant coatings, and more.

◉ Third Party Testing Reports 

Laboratory samples entrusted to Zhonghao Heiyuan Chemical Research and Design Institute testing.

◉ The report concludes:

Most of the physical and chemical indexes of the recycled carbon black treated by the complete processcombination of ash removal, activation and modification reached the level of national standard commercial carbonblack N660, and the physical and mechanical properties were better than that of a brand of commercial carbon blackN660 in the market.
