商品介紹
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.

開口劑二氧化矽介紹
該產品的化學性質穩定，能有效防止膜粘附，降低摩擦係數，使膜卷緊湊平滑，減少皺紋，便於進行膜的二次分切或展開，並有助於潤滑劑或抗靜電劑的均勻遷移。
在功能上，開口劑矽膠的主要作用是防止材料粘附。例如，在塑料薄膜的生產過程中，將矽膠製成的開口母粒添加到聚乙烯和聚丙烯薄膜中，能在膜表面形成微小突起，減少膜之間的接觸面積，從而減少膜之間的摩擦，使膜更容易展開而不粘附。
我們的產品具有良好的分散性，不會產生很多晶點。粒徑適中且均勻分布，不易堵塞過濾網。折射率與樹脂相似，最大程度地減少對膜的透明度的影響，減少設備磨損，具有自然均勻的顏色。不會刮傷膜表面，不影響包裝效果。
對於具體應用，一般使用粒徑為3-8μm的合成矽膠開口劑以粉末形式存在。首先通過雙螺桿擠出機與一定量的載體樹脂混合，熔融塑化成5-10%的高濃度母粒。然後，可以按一定比例添加到膜產品中，與其他添加劑混合形成復合母粒。對於樹脂製造商，可以在聚合物生產過程中添加少量的0.1%至1%，製作專用材料供下游膜製造商使用。適用於行業中的常見品種，開口劑的添加量根據不同類型的膜而變化。
應用領域：雙向拉伸聚丙烯薄膜（BOPP）、鑄造聚丙烯薄膜（CPP）、聚烯烴吹塑薄膜（PP、PE）、雙向拉伸聚酯薄膜（BOPET）、雙向拉伸尼龍薄膜（BOPA）
