## Foam Crosslink XPE Sephrafum: New Generation of Advanced 3D Structure Insulation\r\n\r\n\r\n\r\nThe Sepahfum Collection, as the only exclusive manufacturer of Cross Polyethylene Foam (XPE) in Iran, proudly offers a product to the country\'s industries that offers a new definition of performance, durability and efficiency. The XPE foam, beyond a conventional polyethylene foam, is an advanced engineered material that achieves a 3D and sustainable structure through the Crosslink process. This unique technology has strongly enhances the physical, thermal and chemical properties of the foam and has made it an unrivaled option for a wide range of industrial, construction and automotive applications.\r\n\r\n\r\n\r\n### Technical Analysis and Technology Foam Crossing (XPE)\r\n\r\nThe absolute superiority of the XPE foam over standard polyethylene foam lies in its technology. Understanding this process is the key to recognizing the exceptional capabilities of this product.\r\n\r\n** What is the Crosslink Process? **\r\n In the production of conventional polyethylene foams, polymer chains are linear and independent of each other. But in the production of the XPE foam, using a \"Curing Agent\" and heat, cross-link bonds are created between these chains. These links create a solid, integrated 3D network throughout the foam structure. This lattice structure, like a molecular skeleton, transforms the properties of matter in a fundamental way:\r\n ** Increased thermal stability: ** Connected chains are much more resistant to heat and the foam softening point increases sharply.\r\n ** Improvement of mechanical properties: ** tensile strength, rupture resistance and compressive strength due to the presence of 3D network, far higher than standard foam. This foam has great reversibility after compression (Compression Set).\r\n ** Increased chemical resistance: ** The dense and continuous molecular structure minimizes foam permeability to solvents, acids and corrosive chemicals.\r\n ** Lifestyle and Longevity: ** This foam is much more resistant to destruction due to environmental factors and persistent pressure and maintains its properties for many years.\r\n\r\n\r\n\r\n### Technical specifications\r\n\r\n| Technical Feature | Specifications / value Description |\r\n| : --- | : --- | : --- |\r\n| ** Product Name ** | Chemical Cross Polyethylene Foam (Xpe Foam) Exclusive product of Sepehrfum in Iran\r\n| ** Cell structure ** | Closed-Cell with lattice structure Maximum resistance to moisture and heat\r\n| ** Density range ** | 30 to 200 kg / m3 Production Ability Based on Careful Application Requirements\r\n| ** Product Form ** | ** Roll: ** Thickness 3 to 35 mm ** Board: ** Thickness 40 to 120 mm | High variety to cover all industrial needs\r\n| ** thermal conductivity coefficient (λ) ** | Very low (about 0.035 w/m.K) Extraordinary thermal and refrigeration insulation\r\n| ** thermal resistance ** Sustainability over wide temperature (above ordinary foam) Suitable for insulation of heating and cooling equipment\r\n| **

### Polyethylene Foam: Advanced cell-pistol technology for smart insulation and protection\r\n\r\n\r\n\r\nIn the modern world where productivity, safety, and adaptability in various industries, from packaging and transportation to construction and automotive, the first word, Polyetheylene Foam as an engineered and advanced material offers unbelievable solutions. This innovative product, composed of clever composition of polyethylene polymer and billions of imprisoned air bubbles, is recognized as a thermal, refrigeration, moisture and sound insulation, as well as a powerful impact, thanks to the unique cell-closed-cell structure. This article illustrates the construction technology, prominent features and strategic benefits of polyethylene foam.\r\n\r\n\r\n\r\n### Technology in the heart of the product: the process and structure of the polyethylene foam\r\n\r\nThe functional superiority of the polyethylene foam stems directly from the advanced production process and its microscopic structure. This foam is the result of a compact polyethylene combination with fine air bubbles that gives it a cellular structure. Understanding this technology is the key to identifying this product\'s extensive capabilities.\r\n\r\n*** Production Process (Foam extrusion): **\r\n Polyethylene foam is produced during a controlled extrusion process. In this process, polyethylene resin granules (usually low -density polyethylene or LDPE) with other additives enter the extruder. Inside the extruder, the resin is melted under high heat and combines with a \"Blood Agent\" which can be gas (such as butane) or chemical. This molten and pressure mixture, at the moment of departure from the Mold of the device (DIE), encounters a sudden drop in pressure. This pressure drop causes the foam rapid expansion and formation of billions of small and uniform bubbles throughout the polymer matrix that creates the final foam structure after cooling.\r\n\r\n** Key Structure: Cell-Cell (Closed-Cell) **\r\n The most important technical feature of the polyethylene foam is its \"cell-pistol\" structure. In this structure, each air bubble is separated from its adjacent cells as a separate, fully sealed cell. These non -interconnected cells create a dam непроницаемый (непроницаемый) against air and fluids. This fundamental characteristic is responsible for the following properties:\r\n ** Unique thermal insulation and cooling: ** The air trapped in these cells is one of the best natural thermal insulators. Since air cannot move between cells (prevention of convection) and the polymer itself has low thermal conductivity, heat transfer is greatly reduced. The thermal conductivity coefficient of this foam is usually between 0.030 and 0.042 watts/mm (w/m · k), which makes it one of the most efficient insulators.\r\n ** Absolute resistance to moisture: ** Cell-pistachio structure makes polyethylene foam inherently waterproof. This foam does not absorb water and acts as a vapor barrier and prevents moisture from penetrating the lower layers or packaged goods.\r\n *** AH

## Rock wool insulation: absolute safety against fire and unparalleled energy productivity\r\n\r\n\r\nIn the building industry and modern installations, achieving maximum safety, relaxation and energy productivity is a fundamental principle. Rock Wool, an engineered product of the heart of nature, as a comprehensive and advanced solution, provides a decisive response to all these needs. Made from volcanic stones such as basalt, this insulation is not only a powerful thermal and audio shield, but with its exceptional resistance to fire, it brings a new level of safety to its structures and residents. This article deals with the technical, accurate and comprehensive review of the numerous features and benefits of rock wool insulation and shows why this product is a clever choice for professionals.\r\n\r\n\r\n\r\n### Highlights and technical analysis of rock wool insulation\r\n\r\nStone wool insulation offers a set of unique physical and chemical properties that distinguish it from other insulators.\r\n\r\n*** Exceptional Fire Performance (Exceptional Fire Performance) **\r\n\r\n One of the most prominent features of stone wool is its inherent resistance to fire. This product is made of mineral fibers whose melting point is more than 1000 degrees Celsius (some sources have been mentioned up to 1300 degrees Celsius). The wool does not fire, it does not ignite and does not help to spread the flame. At the time of the fire, the insulation acts as a \"fire barrier\" and can withstand direct flame for up to 4 hours. This feature provides a valuable time for residents and fire extinguishers. In addition, the wool does not release smoke and toxic gases when exposed to high heat, which is one of the main reasons for the deaths of fires. This superior performance puts it in accordance with the most rigorous world fire standards such as the Euroclass A1 and ASTM E84.\r\n\r\n** Very low thermal conductivity (Excellent Thermal Conductivity) **\r\n\r\n The main task of an insulation is to prevent heat transfer. The stone wool performs the best by trapping millions of small air holes in its dense and intertwined fibers structure. This unique structure disrupts all three heat transfer mechanisms:\r\n ** Conductor: ** Mineral fibers are inherently poor conductive heat.\r\n ** Convection: ** The air in the fibers prevents heat flow and transfer.\r\n ** Radiation: ** The density of the fibers prevents the passing of radiant thermal waves.\r\n The thermal conductivity coefficient (λ) of the rock wool is usually less than 0.040 watts/mm (w/m · k), which places it in the category of the best thermal insulators. This feature means dramatically reducing heating and cooling costs and providing stable temperature comfort in different seasons of the year.\r\n\r\n** ** Superior Acoustic Properties) **\r\n\r\n The non -oriented and porous structure of the stone wool has made it a superb sound attraction. This insulation by reducing sound transmission between spaces and absorbing sound waves,
