Introduzione del prodotto
Product Introduction
The amorphous silica made by German Netzsch equipment is a high-performance additive, serving as a matting, anti-blocking and antiblocking agent. It can fully substitute similar products like AB905 from American PQ Company and Sylobloc series from Grace. Widely applied in plastic masterbatches and films such as polyolefin and polyester (PET), as well as in combinations with PP, PE and PVC. Its porous nature effectively reduces adhesion and molecular cohesion, minimizing the adhesion tendency to ensure efficient production and use.
Product Features
- Superior Anti-blocking: Effectively resolves material adhesion, guaranteeing product quality.
- Reduces Terminal Yellowing: Significantly mitigates "terminal yellowing", maintaining product appearance.
- High Dispersibility: Evenly disperses in material systems, ensuring stable performance.
- High Transparency: Has minimal impact on film transparency and haze.
Working Principle
Polymer macromolecules' strong intermolecular forces cause film layer adhesion, leading to processing and handling issues. The inorganic silica antiblocking agent forms a microscopic "rough" structure on the polymer film surface, disrupting these forces, reducing adhesion and facilitating layer separation for better film performance and usability.

介绍开口代理二氧化硅
该产品的化学性质稳定，能够有效防止薄膜粘附，降低摩擦系数，使薄膜卷绕顺畅，减少皱纹，便于进行薄膜的二次切割或展开，并促进润滑剂或抗静电剂的均匀迁移。
在功能方面，开口剂硅石的主要功能是防止材料粘附。例如，在塑料薄膜的生产过程中，将由硅石制成的开口母料添加到聚乙烯和聚丙烯薄膜中，可以在薄膜表面形成小的突起，减少薄膜之间的接触面积，从而降低薄膜之间的摩擦，使薄膜在打开时更加顺滑而不粘连。
我们的产品具有良好的分散性，不会产生很多晶点。颗粒大小适中且均匀分布，不易堵塞过滤网。折射率与树脂相似，最大限度地减少了对薄膜透明度的影响，降低了设备磨损，并具有自然均匀的颜色。它不会划伤薄膜表面，也不会影响包装效果。
对于特定应用，通常使用粒径为3-8 μm的合成硅石开口剂，通常以粉末形式存在。它们必须首先通过双螺杆挤出机与一定量的载体树脂混合，以熔融和塑化成5-10%的高浓度母料。然后，可以按照一定比例将其添加到薄膜产品中，并与其他添加剂混合以形成复合母料。对于树脂制造商，在聚合物生产过程中添加少量0.1%至1%以制造专用材料供下游薄膜制造商使用。它适用于行业中的常见品种，添加的开口剂量根据不同类型的薄膜而有所不同。
应用领域：双向拉伸聚丙烯薄膜（BOPP）、铸造聚丙烯薄膜（CPP）、聚烯烃吹塑薄膜（PP，PE）、双向拉伸聚酯薄膜（BOPET）、双向拉伸尼龙薄膜（BOPA）
