About PENOPLEX / Properties / Properties Advanced methods allow for producing a material with an even texture consisting of fine enclosed cells with a size of 0.1-0.2 mm. The material is produced by mixing polystyrene beads at a high temperature and pressure, while adding a foam forming agent. Then the mix is passed through an extruder. A mixture of light Freon gases with CO2 (carbon dioxide) is used as a foam forming agent. Freon gases used in making PENOPLEX® are non-ozone-damaging, nontoxic, and nonflammable. After the boards are manufactured, the remaining Freon gases in them are quickly replaced by atmospheric air. Thanks to their structure, PENOPLEX® boards have stable thermal-insulating properties and high shrinkage resistance. Basic properties of PENOPLEX® insulation boards:
Water absorption is one of the most important properties of insulating materials. Tests of PENOPLEX® sheetd submerged in water have shown that it absorbs water for the first ten days. After that period, it virtually stops absorbing water – after 30 days its water absorption does not exceed 0.4 per cent of its volume. This is because initially water fills in the cells on the surface of the material which were damaged during manufacture or cutting, but water does not penetrate inside the material itself. The thermal conductivity of the boards is 0.028-0.030 W/m°C, which is much lower than that of many other insulating materials. The material’s low water absorption accounts for insignificant fluctuations of thermal conductivity at higher moistures and varies from 0.001 to 0.003 W/m°C. This allows for using PENOPLEX® boards for buildings floors, roofs, foundations, and basements without the use of additional hydro-insulating materials. Comparison of thicknesses of various materials at constant resistance to heat exchange:
NIISF uses PENOPLEX® samples with an average density of 35 kg/?³ as standards for measuring thermal conductivity in testing equipment. Extruded foamed polystyrene is also highly resistant to pressure from vapors. The resistance of vapor penetration of PENOPLEX® boards with a thickness of 20 mm equals to that of a single layer of a bitumen slate. Our tests show that extruded foamed polystyrene maintains its thermal and physical properties after a series of freezing and thawing cycles. According to the conclusion by NIISF, the longevity of PENOPLEX® boards used in protecting structures exposed to varying changes in temperature and humidity and taking into account its reserve coefficient is no less than 50 years. When choosing adhesives, check with the instructions that come with them and make sure they are suitable for use with polystyrene. PENOPLEX® boards come in two varieties: PENOPLEX® 35 (with an average density of 35 kg/?³) and PENOPLEX® 45 (with an average density of 45 kg/?³). In addition to densities, they vary in their thermal properties, shrinkage resistance, and combustibly resistance. PENOPLEX® 35 boards are used for insulating operating and regular roofs, walls, floors, and foundations (including shallow foundations) of buildings and other structures. When making PENOPLEX® 35, we add a highly efficient antipyrene with our patented additive to the mix, which significantly increases the material’s resistance to fire. Testing by the Independent Fire Safety Test Center of St.Petersburg, PENOPLEX® 35 boards were certified as low combustible (GOST 30244-94), low flammable (ST SEV 2437-80), not distributing flame on their surface, moderately ignitable, with a high smoke forming factor. Like wood, when burning extruded foamed polystyrene produces only two gases (CO – carbon monoxide, and CO2 – carbon dioxide), unlike a number of other organic materials, which produce several harmful substances. PENOPLEX® STANDARD boards are intended for insulating foundations (including shallow foundations), operated inverted roofs around their concrete foundations, and floors of buildings and other structures. PENOPLEX® STANDARD does not contain antipyrenes and falls under the G4 flammability group. It is less expensive than PENOPLEX® 35. PENOPLEX® 45 is used for constructing insulation layers in runways, roads and railroads in permafrost regions with frost heaving, and for insulating high-stress floors, foundations, and operated roofs with access for trucks and automobiles. Shrinkage resistance at 10 percent deformation for PENOPLEX® 45 is no less than 0.5 MPa. In other words, with the distributed pressure at an area of 1 sqm is up to 50 tons, the material will not break and its deformation thickness is no more than 10 percent. PENOPLEX® insulating boards are manufactured with a width of 600 mm and thickness of 20 to 100 mm. The standard length of PENOPLEX® 35 boards is 1200 mm, quarter-processed along its perimeter. PENOPLEX® 45 are typically 2400 mm long, quarter-processed at four sides; for railroads – lengths are 4000 mm and 4500 mm, with a straight edge on the shorter side and a special profile (oblique quarter) on the longer side. PENOPLEX® boards are packaged in PET film with UV rays protection, which is fastened by adhesive tape. Packaging height is 40-42 cm; number of boards varies from 4 to 17. The volume of a single package of PENOPLEX® 35 is 0.288 ?³, PENOPLEX® 45 from 0.576 to 1.134 ?³, depending on length. PENOPLEX® boards have been certified by the GOST R system of Gosstandart of Russia and have received a hygienic approval for use as thermal insulating and soundproofing materials by Gossanepidemnadzor Center in St.Petersburg. Extruded foamed polystyrene has high resistance resistance to many materials used in construction. Some organic compounds may soften, shrink, or even dissolve PENOPLEX® boards. Low chemical resistance to:
High chemical resistance to:
Recommended temperature range for PENOPLEX® boards is -50 to +75°C. All physical and thermal properties of the material remain unchanged when it is used within this temperature range. The boards can be stored open air in their original packaging but should not be exposed to sun rays for long periods to prevent the deterioration of the top layer. |
