Ultra-low density proppants are processed using our company's unique new aggregate shaping technology, permeable material filling technology, chemical coating technology, and multi-layer coating technology.
"New aggregate shaping" technology is a material shaping process with independent intellectual property rights, which is different from the traditional alumina sintering process. Our company has selected new mixed materials such as bentonite, kaolin, and coal powder. Through processing techniques such as hollow foaming and combustion shaping, ultra-low-density coated aggregates are manufactured, with an aggregate density of up to 1.38g/cm³.
"Permeable material filling" technology is a material processing process with independent intellectual property rights, which refers to the material filling process added before coating. By high-temperature melting, special modified polymers and medium molecular mixed materials are filled into the aggregate to further enhance the strength of the coated aggregate and reduce the absolute density of the composite.
Furthermore, with our company's unique chemical coating technology and multi-layer coating technology, the ultra-low-density proppants have a bulk density of up to 1.20g/cm³ and can withstand a maximum pressure of 103MPa.
