PVC CPVC PALL RING is the result of the post chlorination of PVC. The level of chlorine is increased from 56-57%, up to as high as 74%, although typically most commercial CPVC resins contain 63 to 69% chlorine. This increase in chlorine level raises CPVC’s maximum operating temperature to 200°F, over PVC’s maximum operating temperature of 140°F. In terms of chemical resistance, PVC and CPVC are very similar. PVC,CPVC PALL RING, TELLERETTE PACKING is widely used in many chemical towers. T.C.I Pall ring is Similar to: glitsch,koch glitsch,lanpac and sulzer Pall ring
Plastic materials for the production of packings for towers have recently been used in many application fields in which formerly were restricted to metals and ceramic materials.
Selection of plastic materials depends on chemical resistance, temperature stability and mechanical strength. Polypropylene has good resistance to chemicals at temperatures up to more than 100 deg.C, polypropylene is superior to polyethylene in most fields.
The basic property of Polypropylene PP - Density: 920kg/m3
Types used: Operational temperature range:
Polypropylene LTHA: up to +110 deg.C
Polypropylene glass-fiber reinforced: up to + 140 deg.C
Polypropylene alkali-proof: up to +110 deg.C
Cold-resistant : to -10 deg.C (depending on the type)
Resistant to acids like hydrochloric acid and sulfuric acid bases like caustic soda solution and causti- potash solution salt solutions like sodium chloride, ammonium chloride alcohols, ketones such as methanol, ethanol, acetone-organic acids like formic acid, acetic acid
No resistant to: strong oxidizing agents such as halogens like fluorine, chlorine, bromine halogenated hydrocarbons aromatic hydrocarbons
As to the resistance, the respective concentrations and temperatures are to be observed.
