Plastic heilex ring also call the crown-type raschig ring, plastic injection molding is a new type of hole filling, first developed abroad by importing this kind of filler device inspired such packing of the research conducted and successfully the development of China-made Heilex ring packing.
Heilex rings unique configuration, so that in addition to a high flux, low pressure drop, corrosion resistance and impact resistance and good performance, there will not be nested between the filler and wall effect of the small and the gas and liquid flow distribution, etc. This packing is good for gas absorption, cooling and air purification process.

Physical & Chemical Properties
Plastic tower packing can be made from heat resistant and chemical corrosion resistant plastics, including polyethylene (PE), polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), polyvinyiidene fluoride (PVDF) and Polytetrafluoroethylene (PTFE). The temperature in media ranges from 60 Degree C to 280 Degree C.
