Carbon black is a product of incomplete combustion of heavy petroleum, and is commonly used as an additive in the geosynthetic materials industry.
Carbon black is a product of incomplete combustion of heavy petroleum, and is commonly used as an additive in the geosynthetic materials industry. Intended to provide UV resistance for geomembranes. In addition, carbon black as an additive provides support for the excellent black technology of geomembranes. According to GB/T 1764-3021, ASTM G R I-GM13, and GM-17 standards, the carbon black content should be tested between 2.0% and 3.0%. According to the testing requirements, polyethylene compound samples can be "baked" in an oven until only carbon black is left. After pyrolysis, the residual substance weighed in the vessel is a mixture of carbon black and titanium dioxide. Research and extensive testing have demonstrated that this range of carbon black can ensure appropriate UV resistance without compromising the mechanical properties of the material.
