FAQ

Can SFT provide customized Carbon Black packaging for bulk orders?

Yes. We offer flexible packaging solutions to meet industrial needs, including 25kg multi-layer paper bags and 500kg/1,000kg bulk jumbo bags. We also support private labeling and customized shipping marks for our global distributors.
How to store carbon black to avoid moisture absorption?

Carbon black should be stored in a cool, dry, and well-ventilated area away from direct sunlight and heat sources. Since it has a high surface area that can adsorb moisture, we recommend: Keeping the original packaging (paper bags or jumbo bags) intact until use. Storing pallets off the ground on racks to prevent rising damp. Maintaining a relative humidity below 60%. If a bag is opened, ensure it is re-sealed tightly or used promptly to maintain its performance in rubber compounding.
