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.

Introduction to Opening Agent Silicon Dioxide
Izi zimpawu ze-chemicals zomkhiqizo zizinzile, ezingavimbela kahle ukuhlanganiswa kwefilimu, zinciphise umphumela wokuhlangana, zenze ukujolisa kwefilimu kube lula, zinciphise ama-wrinkles, zenze kube lula ukwenza ukusika kwesibili noma ukuvulwa kwefilimu, futhi zandise ukuhamba okufanayo kwe-lubricants noma ama-agent anti-static.
Ngokuphathelene nemisebenzi, umsebenzi omkhulu we-agent yokuvula i-silica ukuvimbela ukuhlanganiswa kwezinto. Enkambisweni yokukhiqiza ifilimu yeplastiki, ngokwesibonelo, ukufaka i-masterbatch yokuvula eyenziwe nge-silica kumafilimu e-polyethylene kanye ne-polypropylene kungakha ama-protrusions amancane ebusweni befayela, kunciphise indawo yokuxhumana phakathi kwamafilimu, futhi ngaleyo ndlela kunciphise ukungqubuzana phakathi kwamafilimu, kwenza ifilimu ibe lula ukuvula ngaphandle kokuhlanganiswa.
Uthando lwethu lunokuhamba kahle futhi alukhiqizi amaphuzu amaningi e-crystal. Usayizi wezakhi ufanelekile futhi uhlukaniswe kahle, futhi akulula ukuvimbela isihlungi. I-refractive index ifana neyesikhumba, okunciphisa umthelela ekukhanyeni kwefilimu, kunciphisa ukugqokwa kwemishini, futhi inombala wemvelo nowokulinganisa. Ayikhiphi ubuso befilimu futhi ayithinti umphumela wokupakisha.
Ku zikhumbuzo ezithile, ama-agent avulekile e-silica a-synthetic anobukhulu be-particle obungu-3-8 μ m ngokuvamile asetshenziswa ngendlela ye-powder. Kumele kuqala kuhlanganyelwe nenani elithile le-resin yokuthwala nge-twin-screw extruder ukuze kuhlanganyelwe futhi kuplastikwe kube yi-5-10% ye-masterbatch enokugxila okuphezulu. Ngemuva kwalokho, bangangezwa emkhiqizweni wefilimu ngenani elithile futhi bahlanganiswe nezinye izithako ukuze kwakhiwe i-masterbatch ye-composite. Kubakhiqizi be-resin, inani elincane le-0.1% kuya ku-1% lingezelelwa enqubweni yokukhiqiza i-polymer ukuze kudalwe izinto ezikhethekile zokusetshenziswa abakhiqizi befilimu abaphansi. Kufaneleka ezinhlelweni ezivamile embonini, futhi inani le-agent evulekile elingeziwe lihluka ngokuya ngezinhlobo ezahlukene zezifilimu.
Application areas: Biaxially oriented polypropylene film (BOPP), cast polypropylene film (CPP), polyolefin blown film (PP, PE), biaxially oriented polyester film (BOPET), biaxially oriented nylon film (BOPA)
