Plastic materials for the production of tower packings have recently been used in many application fields which formerly were restricted to metals and ceramic materials.The application fields of the individual plastic materials are determined by chemical resistance, temperature stability and mechanical strength. Polypropylene is the most current thermoplastic in the production of tower packings. Due to its good resistance to chemicals at temperatures up to more than 100℃, polypropylene is superior to polyethylene in most fields.
The basic property of Polypropylene PP T.C.I Hexilex ring
Density: 920kg/m3 Types used:Operational temperature range: Polypropylene LTHA:up to +110℃ Polypropylene glass-fiber reinforced:up to + 140℃ Polypropylene alkaliproof:up to +110℃ Several special types on request Cold-resistant : to -10℃ (depending on the type) Resistant to :acids like hydrochloric acid and sulfuric acid bases like caustic soda solution and caustic potash solution salt solutions like sodium chloride, ammonium chloride alcohols, ketones like methanol, ethanol, acetone org. acids like formic acid, acetic acid. Not resistant to : strong oxidizing agents like oleum halogens like fluorine, chlorine, bromine halogenated hydrocarbons aromatic hydrocarbons. As to the resistance, the respective concentrations and temperatures are to be observed.
