PENOPLEX is extruded foamed polystyrene made by extrusion from general-purpose polystyrene.
The process of extruding polystyrene was invented over 50 years ago in the United States. This methods allows 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.
PENOPLEX® is a representative of a new generation of insulating materials. It is ideal for reducing heat flow. The main advantages of PENOPLEX®; low heat conductivity, minimal water absorption, and high strength-make it indispensable in the residential and industrial construction industry.
