DK series of polymer-grade nano-montmorillonite use the white, moderate charge density mineral montmorillonite, multi-stage purification, stripping to prepare high-purity montmorillonite large aspect ratio, choose a variety of expansion layer fully organic change agents , so as to adapt to different polarities, modified polymers of different structures. Such as polyolefins, polyamides, polyesters, epoxy resins and other thermoplastic, thermosetting polymer and nitrile rubber and other elastomeric polymer material modification. Product Features and application range: nanoclays Department smectite clays (including calcium-based, sodium, sodium - calcium-based, magnesium 基蒙 clay) by stripping dispersion, purification modifications, superfine grade, special organic compound formed The average chip thickness is less than 25nm, montmorillonite content greater than 95%. With good dispersion properties, can be widely used polymer materials industry as an additive polymer materials, nano, improve impact resistance, fatigue resistance, dimensional stability and gas barrier properties, which serve to strengthen the role of the physical properties of the polymer synthesis while improving the performance of material processing. Application of the polymer in the polymer can be added, may be added in the melt blending time (usually screw blend). Products through national identification, enterprises through ISO9001 international quality system certification. General chemical and physical properties consists of: organic derivative of montmorillonite montmorillonite content: 96-98% Color: White powder diameter / thickness ratio: 200 powder size: 99.9% passing 200 mesh lamination thickness: less than 25nm apparent Density: 0.25-0.35g / cc moisture content: less than 3% X-ray diffraction characteristics: Grades DK1 DK2 DK3 DK4 DK5 DK1N X-ray d001nm 2.1 2.4 2.8 3.8 1.5 2.1 hydrophilic surface: DK5> DK2> DK1N> DK3> DK1> DK4 Applications choose Grades adapt polymer modified method DKI PE, PP, PVC melt extrusion DK2 PET, PBT, UP, PC, EP, EPDM, EPR situ polymerization melt extrusion DK3 EPDM, PS , ABS, SBS, PVC melt extrusion DK4 PE, PP, EVA, PS, TPO, TPE melt extrusion melt extrusion DK5 PA situ polymerization DK1N PP, PE, EP, PU, ??UP, PF melt-extruded in situ polymerization National Free Shipping send free samples!
