This thermally\u2011treated kaolin delivers up to 15% reduction in titanium\u2011dioxide consumption while improving scratch resistance and dimensional stability of finished goods, solving common pain\u2011points of poor dispersion, inconsistent whiteness and high formulation cost for industrial compounders. Sourced from high\u2011quality ore deposits, the product supports bulk export with complete COA documentation and REACH\u2011compliant testing reports.Key Features &amp; Real\u2011World Application Benefits<\/p>\n<p style=\"text-align: justify\">&nbsp;<\/p>\n<p style=\"text-align: justify\">01High Brightness &amp; Controlled Particle Size for Coatings<\/p>\n<p style=\"text-align: justify\">Calcined kaolin features ISO brightness 90\u201192% and well\u2011distributed plate\u2011shaped particles. In water\u2011borne and solvent\u2011based paints, it acts as TiO\u2082 extender, enhancing hiding power and scrub resistance of paint films, and stabilizes matte finish for interior architectural coatings. Formulators can lower raw\u2011material cost without sacrificing surface quality.<\/p>\n<p style=\"text-align: justify\">&nbsp;<\/p>\n<p style=\"text-align: justify\">02Reinforcing Performance for Rubber &amp; Polymer Compounds<\/p>\n<p style=\"text-align: justify\">As a reinforcing mineral filler, calcined kaolin improves tensile strength, abrasion resistance and reduces compression\u2011set for rubber parts, hoses and sealing profiles. For PVC, PE and wire\u2011cable insulation materials, it brings high volume resistivity and low water absorption, optimizing electrical insulation performance of cable compounds.<\/p>\n<p style=\"text-align: justify\">&nbsp;<\/p>\n<p style=\"text-align: justify\">03Excellent Chemical Inertness for Multi\u2011Industry Compatibility<\/p>\n<p style=\"text-align: justify\">With stable chemical property and low heavy\u2011metal impurity, calcined kaolin is also widely adopted in papermaking coating, adhesives &amp; sealants and ceramic manufacturing, resisting acid\u2011alkali environment in complex formulation systems.<\/p>\n<p style=\"text-align: justify\">&nbsp;<\/p>\n<p style=\"text-align: justify\">Technical Specifications<\/p>\n<table>\n<thead>\n<tr>\n<th>Test Item<\/th>\n<th>Unit<\/th>\n<th>Typical Value<\/th>\n<th>Test Standard<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>ISO Brightness<\/td>\n<td>%<\/td>\n<td>90\u201192<\/td>\n<td>ISO 2470\u20111<\/td>\n<\/tr>\n<tr>\n<td>D50 Particle Size<\/td>\n<td>&mu;m<\/td>\n<td>1.8\u20112.5<\/td>\n<td>Laser Diffraction<\/td>\n<\/tr>\n<tr>\n<td>Al\u2082O\u2083 Content<\/td>\n<td>%<\/td>\n<td>42\u201144<\/td>\n<td>XRF<\/td>\n<\/tr>\n<tr>\n<td>SiO\u2082 Content<\/td>\n<td>%<\/td>\n<td>52\u201154<\/td>\n<td>XRF<\/td>\n<\/tr>\n<tr>\n<td>Fe\u2082O\u2083<\/td>\n<td>%<\/td>\n<td>&le;0.3<\/td>\n<td>XRF<\/td>\n<\/tr>\n<tr>\n<td>Loss on Ignition<\/td>\n<td>%<\/td>\n<td>&le;0.5<\/td>\n<td>GB\/T 14565<\/td>\n<\/tr>\n<tr>\n<td>pH (10% suspension)<\/td>\n<td>&mdash;<\/td>\n<td>5.5\u20117.0<\/td>\n<td>ISO 787\u20119<\/td>\n<\/tr>\n<tr>\n<td>Moisture (105\u2103)<\/td>\n<td>%<\/td>\n<td>&le;0.4<\/td>\n<td>ISO 787\u20112<\/td>\n<\/tr>\n<tr>\n<td>325 Mesh Residue<\/td>\n<td>%<\/td>\n<td>&le;0.1<\/td>\n<td>Sieve test<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"text-align: justify\">&nbsp;<\/p>\n<p style=\"text-align: justify\">Frequently Asked Questions<\/p>\n<p style=\"text-align: justify\">Q1: What is the difference between washed kaolin and calcined kaolin?<\/p>\n<p style=\"text-align: justify\">A: Washed hydrous kaolin retains natural crystal water, mainly for paper filling and general ceramics. Calcined kaolin is processed under high\u2011temperature calcination; crystal water is removed to achieve higher whiteness, oil\u2011absorption and reinforcing capacity, more suitable for high\u2011end coatings, rubber and cable industries.<\/p>\n<p style=\"text-align: justify\">Q2: Can calcined kaolin partially replace titanium dioxide in paint formulations?<\/p>\n<p style=\"text-align: justify\">A: Yes. Proper addition ratio 10\u201130% of TiO\u2082 weight can maintain hiding power and effectively cut pigment cost, especially for matte paint systems. Formulation adjustment of dispersant dosage is recommended.<\/p>\n<p style=\"text-align: justify\">Q3: What package and shipping terms do you offer?<\/p>\n<p style=\"text-align: justify\">A: Standard package: 25kg multi\u2011layer kraft bag. Support FOB \/ CIF trade terms; COA, MSDS documents are supplied for each batch for customs clearance.<\/p>\n<p style=\"text-align: justify\">Q4: Do you provide custom particle\u2011size grades for special applications?<\/p>\n<p style=\"text-align: justify\">A: Custom D50 particle size, surface\u2011modified kaolin for polymer are available upon customer request. Sample service is supported for lab formulation test.<\/p>\n<p style=\"text-align: justify\">&nbsp;<\/p>\n<p style=\"text-align: justify\">Global demand for cost\u2011effective, eco\u2011friendly mineral fillers keeps growing across coatings, rubber and polymer sectors.
