PolySurlyn Moisture Barrier(PSMB)
Ebdaagaran Padide Co., after many years of research and in order to comply with the latest global standards, introduces " PSMB " (Polysurlyn Moisture barrier) as a replacement for "PMB" (Polykraft Moisture Barrier.) This new product, in addition to being an environmentally friendly product, will prevent huge financial damages caused by " MIC " (Microbiologically Influenced Corrosion) and "CUI" (Corrosion Under Insulation) to equipment used in petrochemical utilities, power plants and refineries.
According to existing statistics, for producing 1000 kg of paper, 15 trees need to be cut. Trees which are considered to be the lungs of our beautiful planet and ensure the health of our atmosphere.
In response, Ebdaagaran Padide Co. introduces its new aluminium Jacketing product with Polysurlyn layer for the first time in Iran.
Polysurlyn is resistant to corrosion under jacketing of metal pipes and equipment. When there is moisture in atmosphere and the metal jacketing is in contact with it, corrosion is inevitable. This phenomenon will occur in any type of implementation (cold, hot, over-the-roof, industrial, and commercial) regardless of the type of insulation.
Polysurlyn used in hot or cold implementations of pipes and storage tanks will act as a barrier to corrosion of internal layer of the jacketing and galvanic corrosion of jacketing, pipe or hot-implemented equipment. Meanwhile, using this polysurlyn 3 layer film (polysurlyn moisture barrier) will prevent formation of pin holes on internal layer of metal jacketings.
Polysurlyn advantages include:
- Low water absorption in comparison to polykraft paper.
- No color change, no tearing and no destruction while in contact with moisture.
- Resistant to scratching during installation.
- High durability and resistance to a wide range of environmental factors threatening metal jacketings with PSMB layer with ASTM E84 and with a fire resistance rating of >25/50.
- Aluminium jacketing with PSMB layer are in compliance to ASTM C1729 Class A standard.
- PSMB can be considered as a small investment and as insurance for protection of valuable metal jacketings and pipes.
- Metal jacketings will be corroded unless Polysurlyn is used.
Polysurlyn | PolyKraft |
Three layers of co-extruded film | Two layers (PE+Paper) |
Omitting pin holes will cause water resistant properties | Pin holes will cause contact of moisture with metal |
No water absorbing, therefore no contact between metal and water | The layer is in contact with paper which is an water absorbent in itself |
