Silica Anti-blocking Agent

Product Specification

Feature

Powerful anti‑blocking & anti‑caking performance: Forms micro‑protrusions between contact surfaces or absorbs excess moisture/oil, reduces interface adhesion. Effectively solves blocking, lumping and sticking issues for plastic films, powder and granular products. Controlled particle size & narrow distribution: Optimized particle structure balances anti‑blocking efficiency and surface quality, avoids large‑particle‑caused defects such as pinholes, fish‑eyes and rough surface. Good dispersibility in multiple matrix: Low agglomeration, evenly dispersed in polyolefin resin for masterbatch, as well as in powder, granular and coating systems; delivers consistent performance across the whole product. High thermal stability: Tolerates high‑temperature extrusion, granulation and processing conditions. No decomposition, discoloration or volatile substances generated during production. Minimal impact on optical properties: Low haze contribution for film applications; keeps original transparency, gloss and visual appearance of finished goods. Great compatibility with other additives: Synergizes well with slip agents, antioxidants, pigments and other functional ingredients; will not counteract the effect of other additives. High chemical inertness & purity: Strictly controlled coarse particles, heavy metals and soluble impurities. Multiple grades support food‑contact, food additive and industrial‑grade scenarios. Wide application versatility: Works for plastic packaging films (BOPP, CPP, PE, PET), food powder, seasoning, fertilizer, coating and rubber industries. Solves both film surface blocking and powder caking problems. Stable batch‑to‑batch quality: Rigorous process control on particle size, oil absorption, moisture and impurity indicators, ensuring stable performance for continuous mass production. Complete documentation available: COA, MSDS, food‑contact certification and technical application guidelines are provided to support formula optimization and production scale‑up.
