硅灰石 Wollastonite
硅灰石化學(xué)式CaSiO3，是一種稀有礦物資源，是獨(dú)特的纖維狀結(jié)果的無(wú)機(jī)粉體材料，具有良好的物理和化學(xué)性質(zhì)。硅灰石有很高的白度，有極高的耐熱性和介電性，有很低的吸水率和吸油率，有較好的耐堿性和良好的助熔性，有低生物耐受性、無(wú)毒無(wú)嗅等特點(diǎn)，是一種理想的白色補(bǔ)強(qiáng)功能性材料。
Wollastonite (CaSiO3) is a rare mineral resource of unique acicular structure with goodphysical and chemical properties. The main features of wollastonite are high brightness, high heat resistance and dielectric properties, low moisture and oil absorption rate good alkali resistance, non-hazardous and so on. It’s very good reinforcement filler.

硅灰石礦纖（XWA系列） Wollastonite Mineral Fiber （XWA Series）
硅灰石是**的成針狀纖維結(jié)構(gòu)的白色填充料，其長(zhǎng)徑比可達(dá)到20:1，廣泛的應(yīng)用在各種塑料制品中，可以提高制品的電絕緣性、沖擊強(qiáng)度、抗拉強(qiáng)度，改善制品的線性拉伸和模收縮率，可以部分或完全取代傳統(tǒng)玻纖，起到明顯的增強(qiáng)補(bǔ)強(qiáng)作用。
Wollastonite is the only a pure white filling material with acicular fiber structure, the aspect ratio can up to 20:1, it was widely used in plastics, It can improve the electric insulation, impact strength and tensile strength of products, and it can improve the linear stretching and die shrinkage of products. It can replace the traditional glass fiber partially or completely to offer strengthening significantly.
