Silicone Sealant Raw Material: White Carbon Black | JCT Machinery
In silicone sealant production, white carbon black is used as a thickener, using its high specific surface area and special particle structure to significantly improve the viscosity and rheological properties of the colloid, ensuring good sizing and stability. At the same time, white carbon black enhances the mechanical properties of the sealant, such as tear strength and tensile strength, prevents filler settlement, improves touch, reduces shrinkage during the curing process, and ensures the durability and use effect of the final product.
