In silicone rubber and organosilicone compounding, fumed silica gives excellent reinforcement but at high cost, strong thickening, pronounced structurization and difficult dispersion with high mixing energy; ordinary precipitated silica has broad particle distribution, low surface area and more impurities, yielding limited tear improvement, whitening and weak strength; mold rubbers and glass sealants with uneven filler dispersion suffer pinholes, sagging and surface defects; paints, inks, tires, shoe soles, cosmetics and toothpastes demand combined particle size, oil absorption, pH and ignition loss that single-source fillers rarely cover. For specifications demanding "micron scale, narrow distribution, high surface area, good dispersion and reinforcement, partial fumed silica replacement", a strictly controlled precipitated silica places cost-performance balance at one filler node. Addressing this, Anhui IOTA Silicone Oil Co., Ltd. launches Precipitated Silica IOTA 9002. Characterized by "high-quality silica micron-processed to micron size, properties approaching fumed silica; equipment and process give narrow particle distribution; uniform particles deliver rare high specific surface and good reinforcement/dispersion; used in HTV and silicone rubber to raise tear strength, partially replacing fumed silica and reducing cost; SiO₂ (dry basis) ≥98%; pH 5.0-10.0; mesh 200/400/600/800/1200/2000/3000/4000; BET 140-260m²/g; dry loss ≤6%; DBP absorption 3.0-4.0m³/g; ignition loss ≤7%; heating loss ~5%; for silicone rubber/intermediate/mold rubber/glass sealant and paints/inks/tires/shoe soles/coatings/cosmetics/pesticides/textiles/toothpaste; 10kg/bag, PP-coated woven bag with PE liner, custom available; brand IOTA", backed by "micron narrow distribution + high surface area + multi-mesh", it serves as a precipitated silica reinforcing filler for silicone rubber and multi-industry filling. System Positioning: Precipitated Silica Among Silica Filler Families Within silica filler families, IOTA 9002 is a fine-processed precipitated silica, distinct from fumed silica (smaller primary particle, stronger reinforcement but costly, heavy thickening and structurization), fused/crystalline silica flour (inert filler, no reinforcement activity), ordinary broad-distribution precipitated silica (uneven, low surface, poor dispersion). IOTA 9002 uses narrow distribution and uniform micron particles for high surface area, balancing dispersion and reinforcement, properties near fumed grade. It positions as a universal precipitated silica for "HTV/silicone tear reinforcement + mold rubber/glass sealant thickening + paint/ink/tire/shoe/coating/cosmetic/pesticide/textile/toothpaste filling", rather than a mere extender. Particle Architecture: Quality SiO₂ Micron Processing + Narrow Distribution + High Surface + Eight Mesh + Low Loss IOTA 9002 uses quality silica micron-processed to uniform size with narrow distribution. Narrow distribution reduces stress concentration from coarse particles and agglomeration from fines, enabling BET 140-260m²/g; abundant surface silanol hydrogen-bonds with silicone chains to markedly raise tear strength; eight mesh grades (200-4000) cover coarse fill to fine dispersion for HTV, mold rubber, glass sealant and fine chemicals; SiO₂ ≥98% (dry basis) ensures purity, reducing metallic impurities that affect cure and yellowing; pH 5.0-10.0 fits varied acid-base windows; DBP 3.0-4.0m³/g reflects moderate oil absorption and thickening; dry loss ≤6%, ignition loss ≤7%, heating loss ~5% guarantee low volatiles and storage stability. Performance Leap: From "Fumed Costly Thickening, Ordinary Precipitated Weak" to "Micron Narrow, High-Surface Strong Tear" With IOTA 9002, silicone and multi-industry formulations improve jointly: reinforcement—high-surface silanols hydrogen-bond silicone chains, raising tear strength and mechanics, partially replacing fumed silica; dispersion—narrow uniform particles reduce agglomeration, ease powder incorporation, give smoother compounds and fewer pinholes/sagging in mold rubber and glass sealant; cost—precipitated route lowers raw material and energy cost versus fumed while retaining reinforcement; multi-industry fit—acts as matting/thickening in paints/inks, reinforcing/wear in tires/shoe soles, thickening/suspension in coatings, mild abrasive/carrier in cosmetics/toothpastes, suspension in pesticides, functional filler in textiles; stability—low ignition and heating loss ensure batch consistency. Application Penetration: From HTV Tear Reinforcement to Multi-Industry Filling IOTA 9002 covers two core scenarios. Silicone systems: HTV, silicone rubber, silicone intermediate, mold rubber, glass sealant—emphasizing tear strength, dispersion, reinforcement, partial fumed replacement; trial by mesh and surface area. Multi-industry filling: paints/inks/coatings matting-thickening-suspension; tires/shoe soles reinforcement-wear; cosmetics/toothpaste mild abrasive and carrier; pesticide suspension; textile functional filling; trial by mesh and DBP. ⚠️ Taboo: store dry, ~5% heating loss means moisture affects dispersion; keep woven bag with PE liner sealed; avoid strong alkali that may dissolve surface silanol; control impurities per industry hygiene standards. IOTA Technical Guide: Select Mesh Grade, Dry Feed, Bag Moisture-Proof IOTA 9002 is a white micron powder in 10kg/bag, PP-coated woven bag with PE liner, custom available. For silicone reinforcement, select mesh 200-4000 and BET 140-260m²/g by target tear and dispersion; dry before mixing to avoid bubbles from heating-loss moisture; for other industries, trial by mesh and DBP oil absorption. Store dry ventilated with liner sealed; manage as general chemical. Industry Insight: Precipitated silica selection is not the higher surface area the better, but using particle distribution for dispersion and agglomeration, BET surface for reinforcement density, mesh for fineness and thickening, pH and ignition loss for system compatibility and storage stability. For silicone compounders and multi-industry formulators, IOTA 9002 uses one silica with ≥98% SiO₂, BET 140-260m²/g, eight mesh grades and DBP 3.0-4.0m³/g across HTV reinforcement and cross-industry filling, taking micron narrow distribution, high-surface reinforcement and low-loss stability as batch-checkable anchors, achieving partial fumed replacement with cost-quality win.
