Plastic Cascade Mini Ring (CMR) is a modern chemical top cap made of heat-resistant and chemically resistant plastics such as:

  • polyethylene (PE)
  • polypropylene (PP)
  • reinforced polypropylene (RPP)
  • polyvinyl chloride (PVC)
  • chlorinated polyvinyl chloride (CPVC)
  • polyvinylidene fluoride (PVDF)

Plastic cascade mini ring is applied in absorption and cleansing.

The main advantages of plastic cascade mini rings (CMR):

  • Economic feasibility
  • High productivity
  • The variety of sizes
  • Open structure and preferred vertical axis orientation preventing contamination by allowing solid parts to be more easily flushed through the liquid layers.
  • The design of the ring and spokes and the preferred vertical orientation provides a high mechanical strength. That allows the use of these top caps in deep packed columns.
