The PVC type has a top and bottom layer made of PVC coating, with a single-sided tape thickness ≥1.0mm and an inclined angle <16°. The PVG type has nitrile rubber and PVC on the upper and lower layers, featuring TPE properties, with a single-sided tape thickness of 1-3mm and an inclined angle <20°. Structure: Made from the whole core via dipping and plastifying in polyvinyl chloride (PVC) dipping agent or vulcanization. It is fire retardant, antistatic, shock-resistant, abrasion-resistant, and corrosion-resistant. Application: For underground coal mine haulage and material conveyance in metallurgical and chemical industries. Technical Data

STEEL CORD CONVEYER BELT General Steel Cord Conveyer Belt It uses new-type steel cord as the tear-resistant element. It has high tensile strength, small elongation, excellent troughability, and high flexibility, suitable for long-distance, large-volume, and high-speed material conveyance. Tear Resistant Steel Cord Conveyor Belt On one side or both sides, vertical steel cables are evenly laid to reinforce the belt, providing excellent impact and tearing resistance performance. Tear Resist Belt With Detector It uses new-type steel cord as the tear-resistant element. A phase shift sensor (coil) is built into the core rubber and bottom cover of the steel cord conveyor belt at certain intervals. It automatically alarms and stops when a tear is detected or the belt runs abnormally and reaches the preset off speed. Technical Data
