The materials of food conveyor belts mainly include polyurethane (PU), silicone, PTFE, PVC, and stainless steel. Among them, polyurethane (PU) conveyor belt is made of specially treated polyester composite fabric as the carrier skeleton, coated with polyurethane (PU) resin as the carrier surface, which has the characteristics of oil resistance, non-toxic hygiene, easy cleaning, etc., and meets FDA food hygiene standards. Silicone conveyor belts have excellent electrical insulation performance, aging resistance, chemical stability, oxidation and weather resistance, radiation resistance, good breathability, and high and low temperature resistance. Teflon conveyor belt is used between -70 ℃ for low temperature and 260 ℃ for high temperature. It has weather resistance, anti-aging, bending fatigue resistance, and can be used for small wheel diameter, drug resistance, and non-toxic. PVC conveyor belts are lightweight, easy to bend, wear-resistant, and not easily torn, while also having good flame retardancy and insulation properties. Stainless steel conveyor belts have the characteristics of corrosion resistance, high temperature resistance, low temperature resistance, and easy cleaning.
