It is understood that the global conveyor belt market size is 6-700 million square meters per year, and China is the world's largest producer and consumer, accounting for one-third of the world's total production capacity. At present, the world's conveyor belt has ushered in rapid development, and China, as a major coal country, flame retardant conveyor belts are closely related to coal mine safety. After years of development, China has become the world's largest flame retardant conveyor belt production capacity, the future of China will focus on quantity to improve quality and extend the service life, so as to improve the competitiveness of China's conveyor belt. Digging.

It is mainly used in underground coal mines. The characteristics of the belt: the belt body does not delamination, the elongation is small, the impact resistance, tear resistance.
