PLASTIC RANDOM PACKING

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