The production process is roughly as follows: PVC paste making → core impregnation → gel plasticization → adding PVC cover layer → plasticization → stretching and shaping → finished product. This type of conveyor belt has the characteristics of light weight, high strength, tear resistance, good flame retardancy, and simple production process.

This product has the characteristics of high strength, large capacity, and balanced transportation. At the same time, it has good flame retardancy, anti-static, impact resistance, wear resistance, corrosion resistance, and other properties. Its varieties include flame-retardant conveyor belts, mining flame-retardant conveyor belts, coal mine conveyor belts, etc. It has the characteristics of wear resistance, anti-static, waterproof, flame retardant, high strength, excellent safety performance, and lower cost and price compared to other flame retardant conveyor belts. The whole core flame retardant conveyor belt can be divided into PVC type and PVG type. The upper and lower cover layers of PVC type are both made of PVC cover adhesive, with a single-sided adhesive of ≥ 0.8mm. The upper and lower cover layers of PVG type are both made of nitrile rubber and PVC, with a single-sided thickness of 1.5mm-4.5mm. The PVC conveyor belt has a transport inclination angle of less than 16 °, and the PVG conveyor belt has a transport inclination angle of less than 20 °, both of which can be used for transportation above and below coal mines.
