Protection Polyethylene Materials based on polyethylene foam appeared not so long ago. There are two basic types of polyethylene - the radiation crosslinked / chemically crosslinked / physically crosslinked / gas-filled. Most often in construction and packaging uses gas-filled polyethylene. Gas-filled foam is produced using the high-pressure polyethylene, various dyes and fire-fighting supplements / flame retardant / foam physical eg butane or its mixture with other gases. Proceedings of polyethylene for use in a wide range of temperatures /-60 C. to +80 C / up to 100% humidity. Foam has low thermal conductivity - 0.38 W / m C and at a thickness of 1 cm in its thermal conductivity is approximately equal to 7 cm pine timber or 14cm brickwork. Hardly inflammable, the ignition temperature is 306 C, and autoignition 417 C. Water absorption of about 0.6% of the total amount due to the structure of closed-cell foam. Foam does not rot, is not toxic, flammable, is used as the substrate under the laminate coating, as insulation water and sewage pipes / pipe shell / as packaging and cushioning material in furniture, electronic, glass and other industries. On the basis of polyethylene and aluminum foil was created heat-reflective insulation with unique characteristics. At a small thickness it has excellent heat reflection and thermal insulation properties. Currently, foil insulation is used as heat-reflective insulation in industrial and residential buildings, systems, hot and cold water, for air duct insulation, refrigerators, freezers. Foil insulation with adhesive provides ease of installation and allows its use on all surfaces cleaned from moisture, dust and dirt. Its application allows to achieve a good result for complex designs with angles, curves and drops. Used to insulation and sound insulation of refrigerators, cars, vans, marine and river vessels, containers, ventilation, air conditioning and exhaust systems. When protecting heat reflecting...
