The plastic random packing is made of anti- chemical corrosion materials, such as: polyethylene (PE), polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chloridized polyvinyl chloride (CPVC) and polyvinylidene fluoride (PVDF). The feature is that: high void ratio, low pressure drop, sufficient gas liquid contact, small specific weight, and high mass transferring efficiency and so on. The operation temperature is within 60-150℃。It is widely used in petroleum, chemical, alkali-chloride, coal gas and environmental protection, etc.
