The full name of extruded board is called extruded polystyrene foam board, also known as XPS board. Polystyrene foam is divided into two types: expandable EPS and continuous extruded XPS. Compared with EPS board, XPS board is the third generation of rigid foamed insulation material. It overcomes the complicated production process of EPS board and has the superior performance that EPS board cannot replace. It is made of polystyrene resin and other additives through an extrusion process with a continuous and uniform surface layer and a closed-cell honeycomb structure. These thick honeycomb-structured plates have no gaps at all. This kind of closed-cell structure Insulation materials can have different pressures (150-500Kpa) and at the same time have the same low thermal conductivity (only 0.028W/MK) and enduring excellent thermal insulation and compressive performance, and the compressive strength can reach 220-500Kpa.

The extruded board is made of polystyrene resin supplemented by polymer while being heated and mixed, and the catalyst is injected, and then the rigid foam board with continuous closed-cell foaming is extruded and the inside is an independent closed-cell structure. An environmentally friendly thermal insulation material with excellent properties such as high compression resistance, low water absorption, moisture resistance, air tightness, light weight, corrosion resistance, super anti-aging (almost no aging in long-term use), and low thermal conductivity.

Extruded board is widely used in dry wall insulation, flat concrete roof and steel structure roof insulation, low-temperature storage ground, parking platform, airport runway, highway and other fields of moisture-proof insulation, control ground frost heave, it is the current construction industry inexpensive, high-quality heat-insulating and moisture-proof materials. Comparing to mineral wool, xps board has better thermal conductivity performance. In recent years, xps board has became a popular building materials which has large demand. For any interest, please let us know, more details will be sent to you
