挤塑保温板，即挤塑聚苯乙烯保温板，是一种以聚苯乙烯树脂为原材，加入其它聚合物后，经加热挤塑形成的一种发泡硬质塑料板。板内形成许多具有封闭性的气泡结构，有承压力强、防水性能好、耐化学腐蚀和较强的抗老化能力的特点，被广泛应用在建筑物保温和潮湿环境的防水防潮中。
Extruded thermal insulation board, namely extruded polystyrene thermal insulation board, is a kind of foamed rigid plastic board, which takes polystyrene resin as raw material, after adding other polymers, and is extruded by heating. There are many closed bubble structures formed in the board, which have the characteristics of strong pressure bearing, good waterproof performance, chemical corrosion resistance and strong anti-aging ability. They are widely used in building insulation and waterproof and moisture-proof environment.
挤塑保温板在我国真正具有实际意义的发展时间，不过是10年左右。但是近几年来，通过各生产企业的大力推广，已经逐步得到了广大建筑行业业内人士的认可，在国内各主要经济区域中有了较大的覆盖范围。在可见的未来，这一块的市场仍将持续增长，国内的生产能力仍然有提高的空间。
The development time of extruded insulation board in our country is really meaningful, but it is only zhujian.37ix.com.cnshidiaocs.37ix.com.cnshidiaorw.37ix.com.cn suliaotp.37ix.com.cnsujiaopvc.37ix.com.cnsujiaodb.37ix.com.cnabout 10 years. However, in recent years, through the vigorous promotion of production enterprises, it has gradually been recognized by the vast number of construction industry professionals, and has a larger coverage in the major economic regions of China. In the foreseeable future, the market in this area will continue to grow, and there is still room for improvement of domestic production capacity.
