This product is covered by flame retarding double sizing and its belt core is composed of nylon canvas and polyester canvas. It is manufacturing through such processing procedures as rlling. moulding and vulcanization. It could be used to transport non-corrosive block-like, grain-like and powder-like materials in flammable and combustions like mines and thermal power plant , such as bulks and products like coals.
