超微粉天然硫酸鋇(重晶石粉) ULTRABITE 2002W

ULTRABITE 2002W是控制處理加工下, 具有優異的高純度和高白度, 之高等級超微細重晶石粉 ,平均粒徑為2 µm,最高粒徑為15µm。
ULTRABITE 2002W is a superior micronized barite powder, featuring excellent high-purity and High brightness, processed under controlled to mean particle size at 2 micro and a top particle size of 15 microns.
ULTRABITE 2002W 是目前業界營銷最好的天然硫酸鋇。建議用於橡膠化合物、塑膠化合物、光澤琺瑯汽車漆、印刷油墨和粉末塗料的配方。與合成硫酸鋇相比, ULTRABITE 2002W 在樹脂化合物中的吸油量較低, 分散性較好;在目前的應用中, 已被廣泛用作功能增強和填料, 其增強之特性高於合成硫酸鋇 。
ULTRABITE 2002W is the most finest natural barium sulfate in current commercialized proceeding.
It is recommended for using in rubber compounds, plastic compounds, gloss enamels automotive Paints, printing inks and powdered coating formulating. Compare to the synthetic barium sulfate, ULTRABITE 2002W have lower oil absorption & better dispersion in the resinous compound; have been widely used as function reinforcement & filler for advance performances higher than the synthetic barium sulfate in current applications.

NOVABRITE耐化矽(Silica powder)

1.在耐磨橡膠製品中的應用:
 
橡膠板,管,帶,輥,製品中要求混鍊膠應具有很好的滲透性和較強的粘結性,填充矽微粉的混鍊膠充分表現了膠料滲透性,粘結性及分散性良好等獨特性能,且利於在帆布上的擦塗及增強膠片與帆布之間的粘著強度,扯斷強度  ,永久變形等機械性能均有明顯改善並增強耐磨性.
2.在矽橡膠製品中的應用:
 
低含水量,優良的絕緣性,特殊晶象,粒度小並具有一定的補強性能.
3.適用添加於製造戶外塗料:
如屋頂 , 戶外木器和外牆塗料 , 可控制溫度和氣體透過率 , 降低光透射到塗膜內部 , 使塗料不易褪色 , 耐候性和耐降解性高 , 具消光作用,能提高塗膜的光滑性 . 亦可應用於溶劑型塗料 , 水性建築塗料 , 工業底漆和麵漆以及粉末塗料 , 易分散在水性與溶劑型及無溶劑型塗料中 . 用於環氧富鋅底漆 , 易隨著塗料的流動而排列定向,使其在幹膜中和基面平行 , 這樣形成的物理遮罩層可以阻礙濕氣的透過提高塗膜的耐水性和耐濕性 .
