The synchronous belt materials mainly used in industrial production are mainly divided into two types, one is rubber material, the other is polyurethane. We will design the corresponding material performance according to the purpose of the product, so as to meet the increasingly rich industrial production demand. So, which material is better for manufacturers? Let's learn and study together.

Most of the rubber synchronous belt is made of chloroprene rubber imported from Japan. According to the use of the products, different auxiliary materials are added. The framework material is also made of glass fiber rope imported from Japan. The strength layer of glass fiber is a rope made of multiple strands of glass fiber spirally wound along the width of the tape at the node position. It has the advantages of high strength, low elongation, corrosion resistance and heat resistance. The chloroprene rubber tape is firmly bonded to the node line position through the glass fiber. In a word, it is strong and resistant to use!

Polyurethane synchronous belt, also known as PU synchronous belt, is also a very common material, most of which are composed of thermoplastic polyurethane and high strength steel wire. Thermoplastic polyurethane is a material with high wear resistance, and various types of internal core can ensure that it can maintain good movement ability in the transmission process. The opening Pu synchronous belt has reliable transmission and stable size. In the production process of the enterprise, adding a layer of nylon on the tooth surface or back can ensure the particularity of operation in special applications. Of course, a thick layer of polyurethane can be added on the back of the belt, which can effectively prevent the phenomenon of high corrosion or high load.

So which kind of synchronous belt works well?

Polyurethane synchronous belt: Polyurethane synchronous belt is generally made of nylon wire (or steel wire, copper wire) as tensile body and cast by polyester. It has the characteristics of oil resistance, impact resistance and beauty.

Rubber synchronous belt: rubber synchronous belt has good flexibility and wear resistance, but Pu is not water resistant. It has poor reciprocating performance and high and low temperature performance. Under the static condition of normal temperature, PU polyurethane synchronous belt is good, while rubber synchronous belt is good.

In the final analysis, the two materials are currently selected by synchronous belt manufacturers. In fact, there is no standard in the industry to identify which is better. It is the best choice to customize the synchronous belt according to their own needs.
