MPP（Microcellular Polypropylene），中文名稱為微孔發(fā)泡聚丙烯材料，主要組成成分

為空氣和聚丙烯，其制備過程綠色環(huán)保，無毒、無氣味，沒有任何化學物質(zhì)殘留。材料內(nèi)部

的泡孔直徑均在 0.1-50μm 之間，孔密度 10⁷-10⁹個/cm3，且材料整體密度相比發(fā)泡前可減

少 5%-95%。與未發(fā)泡材料及普通泡沫塑料相比，微孔聚合物材料具有缺口沖擊強度高、

韌性好、比強度高、疲勞壽命長、熱穩(wěn)定性高、介電常數(shù)低、熱導率低等優(yōu)異性能，可

用于制造食品包裝、輕質(zhì)-高強-隔音的飛機和汽車部件、緩沖性強的運動器材、高電壓

絕緣材料、保溫性優(yōu)異的纖維材料和低摩擦的表面改性材料等，這些*的優(yōu)點均是普

通泡沫塑料所無法具有的。

MPP is called microcellular polypropylene, the main components are air and polypropylene,the preparation process is green, non toxic, odorless, without any chemical residue. The cell diameter inside the material is between 0.1-50μm, the hole density is 10⁷-

10⁹/cm3, and the overall density can be reduced by 5%-95% compared with that none

-foamed materials.Compared with un-foamed materials and ordinary foams, microcellular materials own high notched impact strength, good toughness, outstanding specific strength, long fatigue life, high thermal stability, low dielectric constant, and low thermal conductivity, which can be used in the manufacture of food packaging, lightweight, high

-strength, sound-proof aircraft and automotive parts, cushioning sports equipment, high

-voltage insulation materials, fiber materials with excellent insulation and low-friction surface modification materials. And the ordinary foams cannot have these unique advantages. Therefore, one can meet the microcellular materials, which will become one of the most valuable and development materials in the 21st century
