Anti-blocking Silica

Product Specification

Feature

Efficient anti‑blocking effect: Creates uniform micro‑protrusions on material surfaces to lower actual contact area between layers, effectively mitigating sticking and blocking caused by pressure, heat and long‑term stacking for plastic films and powder materials. Low haze & good optical performance: Narrow particle‑size distribution minimizes haze increase, retains high transparency and gloss of finished products, ideal for transparent packaging materials. Excellent dispersion performance: Low agglomeration tendency, disperses uniformly in polyolefin resins during masterbatch extrusion, reduces fish‑eyes, pinholes and surface blemishes on final products. Outstanding thermal stability: Withstands high temperature during extrusion, granulation and film stretching processes, no decomposition, yellowing or volatile emissions, adapts to high‑speed production lines. Good synergy with slip agents: Achieves well‑balanced friction coefficient when combined with slip additives, ensures smooth winding, slitting and other converting operations. Little interference to post‑processing: Does not compromise printing, metallizing, laminating and coating performances of films, maintains proper surface tension for subsequent processing. High‑purity quality with strict impurity control: Coarse particles, heavy metals and volatile contents are tightly managed. Food‑contact compliant grades are available for food packaging scenarios. Wide application scope: Suitable for BOPP, CPP, PE, PET and other plastic films; also applicable as anti‑caking additive for powder and granular industrial & food formulations. Reliable batch‑to‑batch consistency: Stable indicators including particle size, oil absorption and moisture, guarantees steady performance for continuous large‑volume manufacturing. Full set of supporting documents: COA, MSDS, relevant compliance certificates and application technical guidance are offered to support formula tuning and production scale‑up.
