There are kinds of materials for rasching ring, such as PP, PVC, CPVC, PVDF, PTFE, PE.
The plastic raschig ring is a loose packing. The shape is simple. It is a circle whose height is equal to its diameter. Rasicyclic ring has excellent resistance to acid and heat, resistance to various inorganic acids, organic acids and organic solvents except hydrofluoric acid corrosion, can be used in a variety of high temperature occasions. Plastic ring fillings are mainly divided into: polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyvinylidene fluoride (PVDF), chlorinated polyvinyl chloride (CPVC), reinforced polypropylene (RPP), etc. According to different requirements, the materials used are different, the commonly used ring is pp ring, PVC ring, RPP ring and so on. Plastic ring packing applications are very wide, can be used in chemical industry, metallurgy, gas, environmental protection and other industries drying tower, absorption tower, cooling tower, washing tower, regenerated tower.

Functional Characteristics:
Plastic ring is the earliest ring packing with fixed geometry in the history of tower packing
simple structure, low price, but there are uneven liquid distribution and serious wall flow channel flow phenomenon.
corrosion resistance can also withstand kingwater and all organic solvents; Optimum aging life in weather resistant plastics; High lubrication with minimum friction coefficient in plastics (0.04); Having the smallest surface tension in a solid material and not adhering to any substance; nonviscous. Non-toxic with physiological inertia; Excellent electrical properties, is the ideal grade C insulation material. Widely used in national defense, atomic energy, petroleum, radio, electric machinery, chemical industry and other important departments.
