• Specific Surface Area: 150–200 m²/g (BET method), ensuring high adsorption and anti-blocking efficiency.

• pH Value: 6.5–7.5 (neutral), safe for non-reactive interaction with film materials.

• Density: ~2.0 g/cm³, bulk density 0.2–0.4 g/cm³, facilitating metering and dispersion.

II. Iziqhamo Eziyinhloko Zobuchwepheshe

1. Anti-Blocking Performance

• Mechanism: AB750 e ya go fetoha go filimi fa nakong ya tshegetso, e bopa mekgwa e amanang le micron e e senyang mekgwa ya van der Waals ya mo go le fa go thibela go tsenya (Source: X-Technology Patent).

• Izibalo Ezinembile:

◦ Coefficient of Friction (COF): Reduces from 0.8–1.2 to 0.2–0.4, significantly improving slip.

◦ Opening Force: For PE films with 0.5–1.5% AB750, opening force ≤5 N/15 mm, meeting high-speed packaging line requirements.

2. Ukuphuma & Ukuqina Kwenqubo

• Masterbatch Compatibility: Easily compounded with PE, PP, and other resins into masterbatches, ensuring uniform dispersion in extrusion and avoiding surface defects from agglomeration.

• Thermal Stability: Stable at processing temperatures of 200–250°C, with no decomposition or volatilization, suitable for high-temperature extrusion.

3. Zikhethelo ze-Optical & Mechanical ezilinganayo

• Transparency: Maintains high film transmittance (≥90%) via controlled particle size distribution, ideal for clear packaging films.

• Mechanical Impact: Minimal effect on tensile/tear strength at recommended loadings (≤2%); may even enhance puncture resistance in some formulations.

III. Iziphumo Zokwehla

1. Plastiek Film Produksie

• Izi Zicelo Eziyinhloko:

◦ Ukupakisha Ukudla: PE cling film, PP shrink film ukuvimbela ukuhlanganiswa ekupakisheni inyama/ukubhaka.

◦ Agricultural Films: Ikwamisa ukuxhoma kwiifilimu ze-PE mulch, ukuphucula ukusebenza kokufaka emhlabeni.

◦ Industriële Verpakking: Rekfolie en zware zakken voor verbeterde stapelbaarheid.

• Izindlela Zefilimu Ezijwayelekile:

◦ LDPE: 0.5–1.0% kuungana kwekushandisa kwepakati.

◦ BOPP: 0.8–1.5% yezi zikhwama nezinto zokubopha.

◦ LLDPE: 0.3–0.8% for high-toughness films (Source: Shunqi Network).

2. Fibers & Masterbatches

• Fiber Modification: Iqinisekisa ukuthi akubambi kwi PP fibers (isb., spunbond nonwovens), kuthuthukisa ukujwayela kwewebhu.

• Functional Masterbatches: Blended with slip agents (e.g., oleamide) to create anti-blocking masterbatches for direct resin addition.

3. Ezinye Izicelo Zezimboni

• Rubber Products: Njengomphumela wesibili wokwandisa ukuhamba phezulu kumatubhu e-silicone nasezivalweni.

• Coatings & Inks: 0.5–1% kuungana kunaboresha kupambana na kuzuia katika mipako inayoweza kupongezwa na UV (Chanzo: Eastmoney).

IV. Iindasitiri Iinobatsira & Kutevedzera

1. Izinzuzo Zokusebenza

• Izindleko-Ezisebenzayo: 30–50% izindleko eziphansi kune fumed silica, ifanele izinhlelo zokusebenza zezimboni ezinkulu.

• Batch Consistency: PQ’s global manufacturing ensures reliable quality, minimizing production risks.

2. Ukuhambisana Nezomthetho

• Ukuphepha Kokuxhumana Nokudla: Kuhambisana ne-FDA 21 CFR §177.2420 (ama-filimu okupakisha ukudla) kanye ne-EU EC No 10/2011 imithetho yeplastiki.
