Because the material is clean and lightweight, it is well suited for industrial formulations that require very fine particle size, consistent dispersion, and predictable performance.In addition, the uniform particle structure helps this walnut shell micro powder blend into compounds, coatings, and composites. As a result, manufacturers can improve processing stability and material properties while supporting more sustainable production. For this reason, the natural walnut shell filler is widely used in plastics, paints, resins, and advanced composite systems.<\/p>\n<hr style=\"border: none; border-top: 1px solid #c9e4d8; margin: 2rem 0;\" \/>\n<h2 style=\"color: #1a5c37;\">Available grain sizes \u2013 walnut shell powder Micro &amp; Filler Grade<\/h2>\n<div style=\"display: flex; flex-wrap: wrap; gap: 12px; margin: 1.2rem 0;\">\n<div style=\"background: #ffffff; border: 1px solid #c9e4d8; border-radius: 8px; padding: 12px 16px;\"><strong>0.001 \u2013 0.1 mm<\/strong> \u2013 ultra-fine organic filler for functional additive applications, ideal for high-precision formulations and controlled dispersion<\/div>\n<div style=\"background: #ffffff; border: 1px solid #c9e4d8; border-radius: 8px; padding: 12px 16px;\"><strong>0.1 \u2013 0.2 mm<\/strong> \u2013 fine fraction for compounds, coatings, and delicate processing, supporting stable performance and consistent results<\/div>\n<\/div>\n<hr style=\"border: none; border-top: 1px solid #c9e4d8; margin: 2rem 0;\" \/>\n<h2 style=\"color: #1a5c37;\">Key technical parameters \u2013 walnut shell powder (micro filler)<\/h2>\n<ul style=\"line-height: 1.7; margin-top: 1rem;\">\n<li><strong>Material:<\/strong> 100% natural walnut shell<\/li>\n<li><strong>Form:<\/strong> powder \/ micro-granulate<\/li>\n<li><strong>Hardness:<\/strong> approx. 3.0\u20133.5 Mohs<\/li>\n<li><strong>Particle shape:<\/strong> irregular, micro-angular<\/li>\n<li><strong>Bulk density:<\/strong> approx. 0.5\u20130.7 g\/cm\u00b3<\/li>\n<li><strong>Moisture content:<\/strong> \u2264 7\u20138%<\/li>\n<li><strong>Biodegradability:<\/strong> 100%<\/li>\n<li><strong>Heavy metals:<\/strong> none<\/li>\n<\/ul>\n<hr style=\"border: none; border-top: 1px solid #c9e4d8; margin: 2rem 0;\" \/>\n<h2 style=\"color: #1a5c37;\">Typical applications \u2013 walnut shell micro powder Micro &amp; Filler<\/h2>\n<h3 style=\"color: #4a8c6f;\">Fillers and functional additives \u2013 walnut shell filler<\/h3>\n<ul>\n<li>paints, coatings, and protective layers<\/li>\n<li>plastics and composites (better stability and appearance)<\/li>\n<li>adhesives, sealants, and resins<\/li>\n<\/ul>\n<h3 style=\"color: #4a8c6f;\">Chemical and materials industry \u2013 natural organic filler<\/h3>\n<ul>\n<li>modification of material properties<\/li>\n<li>eco-friendly alternative to synthetic fillers<\/li>\n<li>biodegradable and circular-economy products<\/li>\n<\/ul>\n<h3 style=\"color: #4a8c6f;\">Precision surface processing \u2013 walnut shell abrasive<\/h3>\n<ul>\n<li>micro-cleaning and gentle matting<\/li>\n<li>processing of sensitive components<\/li>\n<li>laboratory and technical applications<\/li>\n<\/ul>\n<hr style=\"border: none; border-top: 1px solid #c9e4d8; margin: 2rem 0;\" \/>\n<h2 style=\"color: #1a5c37;\">Key advantages \u2013 natural filler and fine abrasive<\/h2>\n<ul style=\"line-height: 1.8;\">\n<li>\u2714 ultra-fine grain size for specialist applications<\/li>\n<li>\u2714 natural and eco-friendly organic filler<\/li>\n<li>\u2714 improved mechanical and aesthetic properties<\/li>\n<li>\u2714 low density and excellent dispersion<\/li>\n<li>\u2714 no toxic or mineral impurities<\/li>\n<li>\u2714 aligned with eco and circular-economy trends<\/li>\n<\/ul>\n<hr style=\"border: none; border-top: 1px solid #c9e4d8; margin: 2rem 0;\" \/>\n<h2 style=\"color: #1a5c37;\">Packaging and logistics<\/h2>\n<ul>\n<li>paper bags with PE liner \u2013 25 kg<\/li>\n<li>technical packaging \u2013 10 kg<\/li>\n<li>big bags \u2013 1000 kg<\/li>\n<\/ul>\n<hr style=\"border: none; border-top: 1px solid #c9e4d8; margin: 2rem 0;\" \/>\n<h2 style=\"color: #1a5c37;\">Safety and storage<\/h2>\n<ul>\n<li>use personal protective equipment (dust masks, goggles)<\/li>\n<li>avoid excessive dust formation during handling<\/li>\n<li>store in a dry and well-ventilated area<\/li>\n<\/ul>\n<h2 style=\"color: #1a5c37;\">Why Ingritech?<\/h2>\n<p>Ingritech Micro &amp; Filler Grade combines stable quality, repeatable parameters, and an eco-friendly raw material base.
