The rubber synchronous belt is made of high-quality chloroprene rubber imported from Japan as the main raw material and various auxiliary materials. The skeleton material is high quality glass fiber rope imported from Japan. The surface of the belt teeth is protected by nylon 66 high elastic canvas. The glass fiber strength layer is a rope formed by multiple strands of glass fiber spirally winding along the width of the tape at the node position.

江苏同步皮带具有强度高、延伸率小、耐腐蚀、耐热等特点。氯丁橡胶胶带背通过玻璃纤维牢固地粘合到节点线位置，玻璃纤维起到保护层的作用。带齿由耐磨性好的尼龙帆布和高剪切强度、硬度合适的氯丁橡胶制成。它需要精确的造型和精确的位置，才可以与带轮的齿槽正确的啮合，它的齿根需要与节距线保持一定的距离，以确保弯曲时没有变化。

Jiangsu synchronous belt has the characteristics of high strength, low elongation, corrosion resistance and heat resistance. The chloroprene rubber tape back is firmly bonded to the node line position through glass fiber, which acts as a protective layer. The belt teeth are made of nylon canvas with good wear resistance and chloroprene rubber with high shear strength and suitable hardness. It needs precise shape and precise position to mesh with the groove of the pulley correctly, and its tooth root needs to keep a certain distance from the pitch line to ensure no change during bending.

聚氨酯同步带又称PU同步带，是由热塑性聚氨酯和高强度钢丝组成。热塑性聚氨酯具有很高的耐磨性，而各种类型的线芯能保证其在传动中仍能保持良好的运动能力，其生产公差小。开口的PU同步带传动可靠，尺寸稳定。在生产过程中，在齿面或背面添加一层尼龙，以确保在特殊应用中操作的特殊性保持不变。皮带背面可添加一层厚的聚氨酯，以防止出现高腐蚀或高负载等现象。

Polyurethane synchronous belt, also known as PU synchronous belt, is composed of thermoplastic polyurethane and high strength steel wire. Thermoplastic polyurethane has high wear resistance, and various types of wire core can ensure that it can still maintain good movement ability in the transmission, and its production tolerance is small. The Pu synchronous belt with opening has reliable transmission and stable size. In the production process, a layer of nylon is added on the tooth surface or back to ensure that the particularity of operation in special applications remains unchanged. A thick layer of polyurethane can be added on the back of the belt to prevent high corrosion or high load.

聚氨酯同步带：聚氨脂同步带一般以尼龙线(或钢丝、铜丝)作为抗拉体，聚酯浇注而成，具有耐油、耐冲击、美观等特点。

Polyurethane synchronous belt: Polyurethane synchronous belt is generally made of nylon wire (or steel wire, copper wire) as tensile body and polyester casting, which has the characteristics of oil resistance, impact resistance and beautiful appearance.

橡胶同步带屈挠性好.耐水性好.PU不耐水.往复工作性差.高低温性能差.耐磨好.在常温静态条件下PU聚氨酯同步带好.反之橡胶同步带好。

The rubber synchronous belt has good flexibility, good water resistance, poor reciprocating performance, poor high and low temperature performance, good wear resistance. PU polyurethane synchronous belt is good under static condition at room temperature, on the contrary, the rubber synchronous belt is good.
