1. The PVC conveyor belt is made of high-strength and high-quality cotton, nylon, and polyester canvas as the belt core. The non-polluting rubber compounding agent is made of white or light-colored, non-polluting, and its rubber surface is made of polyvinyl chloride, which is composed of polyester fiber cloth and polyvinyl chloride glue. The belt body has good elasticity and is not easily deformed. Its temperature resistance is -10℃～+80℃.

2. The PU conveyor belt uses PU environmentally friendly materials: Polyurethane (PU) is used as the raw material for the production of conveyor belts , called polyurethane. This material conforms to food hygiene standards and can be in direct contact with food, with moderate color and no peculiar smell. And it has the characteristics of oil resistance, corrosion resistance, cold resistance, cutting resistance, wear resistance, physical aging resistance, anti-sticking, anti-bacteria, etc. It is a durable conveying product. Its temperature resistance is -20℃～+80℃.
