產(chǎn)品功能與特性                                                                                                                            中國(guó)

VicFil^®  高純度石英粉是由高純度石英巖精制而成，用于制造業(yè)和產(chǎn)品配方中要求結(jié)構(gòu)圓潤(rùn)，化學(xué)特性穩(wěn)定或具有惰性的礦物填料。

VicFil^®  具有完全的化學(xué)惰性和中性酸堿值，不論處在有觸媒或多成分化學(xué)系統(tǒng)下，都不會(huì)產(chǎn)生變化或誘 導(dǎo)反應(yīng)發(fā)生，即使在極高溫度或惡劣環(huán)境下也不會(huì)裂變。

VicFil^® 特有的低比表面積和低吸油量使其在涂 料，粘結(jié)劑，硅橡膠和環(huán)氧樹(shù)脂中具有較高的填充量并增加成品的剛性及耐磨性。高化學(xué)純度及**的絕 緣特性，更適合于耐火耐燃及高絕緣方面之應(yīng)用。

VicFil^®  各規(guī)格產(chǎn)品生產(chǎn)嚴(yán)格控制在 ISO 質(zhì)量保證體系下生產(chǎn)，從而保證產(chǎn)品化學(xué)純度和顆粒分布一致性， 可信賴的服務(wù)對(duì)產(chǎn)品提供有效支持。
