Carbon Black (N550)
Carbon Black N550, also known as Fast Extruding Furnace (FEF) black, is one of the most versatile grades of carbon black used in the industrial sector. It belongs to the ASTM N500 series, characterized by a medium surface area and high structure. This unique morphology provides a superb balance of reinforcing properties, high stiffness, and excellent extrusion characteristics. It is predominantly used in rubber compounds where high dimensional stability and a smooth finish are required. Moonarc Chemicals provides N550 that ensures consistent performance in both natural and synthetic rubber matrices.

Storage
Store in a dry, cool, and well-ventilated area away from strong oxidizers and open flames. Keep containers tightly closed. Prevent exposure to moisture to avoid caking. Ensure bags are stacked stably to prevent tipping. Storage life is virtually indefinite if kept dry.
Handling
Ensure adequate ventilation at the workplace. Use local exhaust ventilation to control dust at the source. Avoid contact with eyes and skin. Do not breathe dust. Wear appropriate personal protective equipment (PPE) including dust masks (N95 or better) and safety goggles. Mechanical handling equipment should be grounded to prevent static discharge.
Transport
Not regulated as a hazardous material for transport by land (ADR/RID), sea (IMDG), or air (IATA) according to the UN Model Regulations. Standard carbon black is not subject to the provisions for 'Self-Heating Substances' (Class 4.2). Non-hazardous for shipping.
