What is the role of plastic step ring in packing that cannot be ignored? Because of the numerous fillers, will be classified into different size specifications. These functions of it will have those advantages in the use of the process.

First, the height to diameter ratio of the plastic ladder ring

It has a height to diameter ratio of only 1/5 of the Bauer ring, while adding tapered flanging at the other end of the ring. The design of this shape can reduce the resistance of gas through the bed. It can also guarantee the larger flux in the process of product use. At present, the main raw materials of the ladder ring used in China are polyethylene, polypropylene and polyvinyl chloride. But the raw material of the plastic step ring is composed of polypropylene, its greater advantage lies in the high utilization rate of the product.

Two, the characteristics of the plastic ladder ring

1, plastic packing has high temperature resistance, but also has acid and alkali resistance. Guaranteed the service life of the ladder. However, it should also be noted that cold brittleness will be affected at low temperatures. Therefore, the step ring is selected before the packaging PVC material is made to avoid the impact of cold brittleness.

2. The ladder ring made of plastic material also has the advantages of low cost, light weight, impact resistance and not easy to be broken. Therefore, it is often used in dust removal, adsorption, extraction devices.
