From the application in terms of insulation materials, insulation materials abroad and R & D applications are generally higher than in domestic insulation materials applications, as early as 1987, 87% in foreign insulation materials are used in the construction of the insulation, abroad Some developed countries but also in the late 1970s had already begun on the building insulation materials research and development, and the government is promoting new construction added to energy saving in terms of material elements.

In the 21st century, building insulation materials market worldwide is rapidly extruded plate thickness specifications 10mm thick it's development, and the construction industry demand for insulation materials is constantly expanding. Because of this, research and development of new insulation materials subject to a high degree of importance, the new R & D means, an endless stream of new insulation materials. Domestic currently being touted is a material called polystyrene, polystyrene is defined by the styrene monomer by polycondensation of radical synthetic polymers, the English name for Polystyrene. It is a colorless, transparent thermoplastic with 100 degrees Celsius higher than the glass transition temperature. And polystyrene insulation material in the construction of the application is more extensive, and polystyrene-based material in the production of polystyrene board insulation properties of the building but also has outstanding performance. Polystyrene is mainly reflected in the mechanical properties, excellent resistance to water, moisture resistance, light weight, high hardness, moldability and other characteristics.

Polystyrene production of wool board pullout tests used in building insulation material around the parties, but discarded polystyrene supplies if not handled properly, then discarded polystyrene biodegradable and can not enter via photolysis biogeochemical cycles. Because of its low specific gravity of expanded polystyrene so that float on the water or with wool board thermal conductivity wind drift, causing damage to the subjective landscape. According to the survey of the California Coastal Commission, polystyrene is a major ocean drift. And this kind of eating plastic marine organisms, can cause damage to their digestive system.

So in terms of environmentally friendly building materials also need to focus on domestic environmental protection wall insulation materials industry, should be vigorously pursued green insulation material products, maximizing the use of existing resources and reduce environmental damage. Recovery and use of insulation materials is currently the need for strict explored.
