Top Quality Amorphous Silicon Powder Silicon Dioxide Powder Improving The Toughness of Plastic / Silicone Rubber / Paint / Coating / Adhesive / FRP / GRP

Introduction:Fumed silica is the superfine micro-nano fine chemical product, which is divided into hydrophilic type and hydrophobic type in accordance with their different surface treatments.Fumed silica includes Hydrophilic type and Hydrophobic type. And each type has many grades, no matter what grade you used before, we will provide the suitable grade of fumed silica to you. Its appearance is white powder. Native particle size ranges from 5nm-40nm, with significant functions of thixotropy, reinforcing, thickening and filling. Therefore, it is widely used in the industries of rubber, sealant, plastic, resin, paint, printing ink, papermaking, medicine, cosmetics, food etc.Properties:* Reinforcing filler in elastomers* Anti-settling, anti-sagging and thickening agent* Rheology control and thixotropic agent* Free flow aid and anti-caking aid for powders* High tear resistanceMain Specifications:GradeHL-200HL-380HB-139HB-151HB-615HB-630Formwhite amorphous powderSurface area (m2/g)200±20380±30100±20130±20160±30320±30PH value3.9-4.53.7-4.55.5-7.53.7-4.55.5-7.55.5-8.0Loss on drying(2h,105ºC) %≤2.0≤2.5≤1.5≤0.7≤0.5≤0.5Loss on ignition (2h,1000ºC) %≤2.0≤2.5≤10≤2.5≤4.0≤4.0silica content (%)≥99.8Tamped density (g/dm²)30-6030-6040-6040-6040-6040-60Surface treatmentNoNoPDMSDDSHMDSHMDS  ApplicationMain FunctionsRecommend GradeSuggested Usage(%)Silicone rubberHTV silicone rubberreinforcing, transparentHL-200, HL-300, HL-380, HB-1320.5 - 3Silicone rubber insulatorreinforcing,insulateHL-150,HL-200,HB-1390.5 - 3RTV silicone rubberrheology controlHL-150,HL-200,HB Series0.5 - 3Powder coatingCorona dischargefree flowing, anti-caking, dispersion, charge controlHB-630,HB-151,HL-200,HL-300,HL-3800.5 - 3VarnishPU, C3H4O2, epoxy-polyester resin, amino   HB-630,HB-151,HL-200,HL-3000.5 - 3Liquid coatingindustrial paint and marine paintanti-sagging, anti-settling, thickening, thixotropy,levelingHB-139,HB-151,HB-6300.5 - 3C3H4O2, olyester resin, UPR resin, nitroanti-sagging, anti-settling, thickening, thixotropyHL-200,HL-3000.5 - 3Epoxy rein, vinyl polyester resin, PUanti-sagging, anti-settling, thickening, thixotropyHB-151,HB-1390.5 - 3SealantPUthixotropy,anti-sagging, water content controlHB-139,HB-151,HL-2003 - 7AdhesiveEpoxyreinforcing, thixotropy, anti-sagging, thickeningHB-139,HB-151, HL-200, HL-3001.5 - 3Composite material   thixotropy, anti-settling, anti-sagging, thickeningHL-200, HL-300, HB-151, HB-1390.5 - 3Packing:10kg/Bag ; White craft paper bag,For 20 GP, 1800kg with 10 pallets, 18bags/pallet ;10kg/ bag.For 40 GP, 3600kg with 20 pallets, 18bags /pallet; 10kg/ bag.For 40 HQ, 4000kg with 20 pallets, 20bags /pallet; 10kg/ bag.FAQs1.
