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.

產品細節
開啟代理二氧化矽介紹
該產品的化學性質穩定，可以有效防止薄膜粘附，降低摩擦係數，使薄膜卷繞平滑，減少皺紋，使二次切割或薄膜放卷更容易，並促進潤滑劑或抗靜電劑的均勻遷移。
在功能方面，開口劑矽膠的主要功能是防止材料粘附。在塑料薄膜的生產過程中，例如，將由矽膠製成的開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突起，減少薄膜之間的接觸面積，從而減少薄膜之間的摩擦，使薄膜在開啟時更加順滑而不會粘附。
我們的產品具有良好的分散性，並且不會產生許多晶體點。顆粒大小適中且均勻分佈，不易堵塞過濾網。折射率與樹脂相似，最大限度地減少對薄膜透明度的影響，減少設備磨損，並具有自然均勻的顏色。它不會刮傷薄膜表面，也不會影響包裝效果。
對於特定應用，合成二氧化矽開口劑通常以粉末形式使用，顆粒大小為3-8 μm。它們必須首先通過雙螺桿擠出機與一定量的載體樹脂混合，以熔融和塑化成5-10%的高濃度母料。然後，可以按照一定比例將其添加到薄膜產品中，並與其他添加劑混合以形成複合母料。對於樹脂製造商，少量的0.1%至1%被添加到聚合物生產過程中，以製造專用材料供下游薄膜製造商使用。它適用於行業中的常見品種，添加的開口劑量根據不同類型的薄膜而有所不同。
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)
