Description

Carbon Black CAS NO 1333-86-4 is a finely divided form of elemental carbon produced by the incomplete combustion or thermal decomposition of hydrocarbons. This versatile industrial material is a critical reinforcing agent and pigment, valued for its ability to enhance the durability, strength, and UV resistance of rubber and plastic products. It is an essential raw material for manufacturers in the tire, rubber goods, plastics, coatings, and printing ink industries seeking to improve product performance and longevity.

Application

• Tire Manufacturing: Primary reinforcing filler for treads, sidewalls, and other rubber components to improve abrasion resistance, tensile strength, and durability.
• Industrial Rubber Goods: Used in belts, hoses, gaskets, seals, and conveyor belts to enhance mechanical properties and extend service life.
• Plastics and Masterbatches: Functions as a UV stabilizer, conductive filler, and black pigment in polyethylene, polypropylene, PVC, and engineering plastics.
• Coatings and Inks: Provides deep black coloration, weather resistance, and conductivity in automotive, industrial, and protective coatings, as well as printing inks.
• Specialty Applications: Used as a conductive agent in batteries, antistatic packaging, and electronic components, and as a pigment in toners and carbon paper.

Quality Control

Our Carbon Black is manufactured under strict quality management systems to ensure batch-to-batch consistency and performance. Key parameters such as particle size, surface area (BET), structure (DBP absorption), and purity are rigorously tested. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing specifications relevant to your application, whether for rubber reinforcement, pigmentary use, or conductive purposes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Keep containers sealed to prevent contamination and moisture absorption, which can affect dispersion properties. Follow local regulations for the storage of industrial powders.
