VicFil^®  高纯度石英粉是由高纯度石英岩精制而成，用于制造业和产品配方中要求结构圆润，化学特性稳定或具有惰性的矿物填料。

VicFil^®  具有完全的化学惰性和中性酸碱值，不论处在有触媒或多成分化学系统下，都不会产生变化或诱 导反应发生，即使在极高温度或恶劣环境下也不会裂变。

VicFil^® 特有的低比表面积和低吸油量使其在涂 料，粘结剂，硅橡胶和环氧树脂中具有较高的填充量并增加成品的刚性及耐磨性。高化学纯度及绝佳的绝 缘特性，更适合于耐火耐燃及高绝缘方面之应用。

VicFil^®  各规格产品生产严格控制在 ISO 质量保证体系下生产，从而保证产品化学纯度和颗粒分布一致性， 可信赖的服务对产品提供有效支持。
