Plastic filler materials include polyethylene (PE), polypropylene (PP), enhanced polypropylene (RPP), polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), and poly (vinylidene fluoride) the vinyl (PVDF), polyphenylene sulfideether (PPS), resistant to corrosion good big gap flux, small resistance, low energy consumption, low operating cost, light weight, easy handling characteristics, and can be reused. Especially for petroleum, chemicals, chlor-alkali, acetic acid, gas, and environmental protection industries in low-temperature (60-150 ℃) stripping, absorption and scrubber process them.
