传统的保温材料或多或少地都有一些缺陷,如有些类型的保温材料的耐热强度非常好,但耐压强度则较差;而另一些保温材料耐压强度虽好,耐火性却差。法国 Maniville 公司发明的一种新型甲阶酚醛树脂泡沫保温板则成功地克服了上述保温材料的不足。 Traditional insulation materials have some defects, more or less, such as some types of insulation materials are very good heat resistance, but the compressive strength is poor; while other insulation materials, although good pressure resistance, fire resistance is poor . A new type of resol foam insulation board invented by Maniville of France successfully overcomes the shortcomings of the above insulation materials.
