Why Soft &amp; Biodegradable Media Exist<\/h2>\n\n<p>Conventional abrasive blasting media \u2014 steel grit, aluminum oxide, garnet \u2014 are designed to aggressively remove material and create anchor profiles. For heavy industrial surfaces, that aggression is desirable. But many manufacturing and maintenance applications involve substrates that are simply too thin, too soft, or too structurally sensitive to tolerate conventional abrasives:<\/p>\n\n<ul>\n  <li><strong>Aircraft skins:<\/strong> Aluminum alloy panels 1\u20133 mm thick cannot be blasted with steel grit without warping or surface damage. Paint stripping must remove the coating without touching the aluminum substrate.<\/li>\n  <li><strong>Carbon fiber composites:<\/strong> Any media that cuts into the fiber matrix causes structural damage. Only the softest abrasives can clean composite surfaces.<\/li>\n  <li><strong>Vintage automotive sheet metal:<\/strong> Thin-gauge steel panels from pre-1980s vehicles warp easily under aggressive media. Plastic media strips paint while preserving panel geometry.<\/li>\n  <li><strong>Food processing equipment:<\/strong> Walnut shell and corn cob are non-toxic, biodegradable, and leave no metallic contamination \u2014 critical for equipment used in food contact applications.<\/li>\n<\/ul>\n\n<h2 id=\"b6-plastic\">2. Plastic Blast Media: Types &amp; Specifications<\/h2>\n\n<p>Plastic blast media (PBM) consists of angular thermoplastic particles manufactured from urea formaldehyde, melamine, acrylic (PMMA), or polyester resins. Different resin types offer different hardness profiles, allowing precise matching of media aggression to substrate sensitivity. The U.S. military specification MIL-P-85891A governs plastic blast media used in aerospace applications and defines four media types:<\/p>\n\n<div class=\"hlh-b6-table-wrap\">\n<table class=\"hlh-b6-table\">\n  <thead><tr><th>\u0422\u0438\u043f<\/th><th>\u0421\u043c\u043e\u043b\u0430<\/th><th>Hardness (Mohs approx.)<\/th><th>Best For<\/th><\/tr><\/thead>\n  <tbody>\n    <tr><td>Type I<\/td><td>Urea formaldehyde<\/td><td>3.0\u20133.5<\/td><td>Softest \u2014 carbon fiber, fiberglass, thin aluminum<\/td><\/tr>\n    <tr><td>Type II<\/td><td>\u041c\u0435\u043b\u0430\u043c\u0438\u043d<\/td><td>3.5\u20134.0<\/td><td>Aluminum aircraft skins, composite structures<\/td><\/tr>\n    <tr><td>Type III<\/td><td>Acrylic (PMMA)<\/td><td>3.0\u20133.5<\/td><td>Precision finishing, electronic components<\/td><\/tr>\n    <tr><td>Type IV<\/td><td>Polyester<\/td><td>3.5\u20134.5<\/td><td>Harder composites, bonded structures<\/td><\/tr>\n  <\/tbody>\n<\/table>\n<\/div>\n\n<h3>Plastic Media Size Grades<\/h3>\n<div class=\"hlh-b6-table-wrap\">\n<table class=\"hlh-b6-table\">\n  <thead><tr><th>Size Grade<\/th><th>Particle Size Range<\/th><th>\u041f\u0440\u0438\u043b\u043e\u0436\u0435\u043d\u0438\u0435<\/th><\/tr><\/thead>\n  <tbody>\n    <tr><td>Extra coarse<\/td><td>1180\u20132000 \u00b5m<\/td><td>Heavy coatings, thick films, rapid stripping<\/td><\/tr>\n    <tr><td>Coarse<\/td><td>850\u20131400 \u00b5m<\/td><td>Standard paint stripping on aircraft and automotive<\/td><\/tr>\n    <tr><td>Medium<\/td><td>600\u20131000 \u00b5m<\/td><td>Multi-layer coating removal, general aviation<\/td><\/tr>\n    <tr><td>Fine<\/td><td>425\u2013710 \u00b5m<\/td><td>Precision stripping, composite surfaces<\/td><\/tr>\n    <tr><td>Extra fine<\/td><td>212\u2013500 \u00b5m<\/td><td>Delicate surfaces, thin primer removal<\/td><\/tr>\n  <\/tbody>\n<\/table>\n<\/div>\n\n<div class=\"hlh-b6-callout hlh-b6-callout-tip\">\n  <strong>\u2705 Aerospace compliance note<\/strong>\n  For use on U.S. military aircraft and aerospace prime contractor programs, plastic blast media must meet MIL-P-85891A certification.

Walnut Shell Grit<\/h2>\n\n<p>Walnut shell grit is produced by crushing the hard shells of English walnuts (Juglans regia) or black walnuts (Juglans nigra), then screening to precise mesh sizes. It is a natural, renewable, and fully biodegradable abrasive with a Mohs hardness of approximately 3.0\u20134.0 \u2014 hard enough to strip paint and clean surfaces, soft enough not to damage aluminum, copper, soft steels, wood, and most plastics.<\/p>\n\n<h3>Key Properties of Walnut Shell Grit<\/h3>\n<ul>\n  <li><strong>Mohs hardness:<\/strong> 3.0\u20134.0<\/li>\n  <li><strong>Specific gravity:<\/strong> 1.2\u20131.4 g\/cm\u00b3 (very light \u2014 lower impact energy than plastic media)<\/li>\n  <li><strong>Free silica:<\/strong> None (natural organic material)<\/li>\n  <li><strong>Biodegradable:<\/strong> Yes \u2014 spent media can often be composted or landfilled as non-hazardous organic waste<\/li>\n  <li><strong>Moisture sensitivity:<\/strong> Walnut shell absorbs moisture readily \u2014 must be stored in dry conditions and moisture content verified before use (&lt;8% for reliable blasting performance)<\/li>\n  <li><strong>Oil absorption:<\/strong> Walnut shell naturally absorbs oils and grease during blasting \u2014 useful for cleaning contaminated surfaces, but the absorbed contamination must be managed in spent media disposal<\/li>\n<\/ul>\n\n<h3>Walnut Shell Mesh Sizes<\/h3>\n<div class=\"hlh-b6-table-wrap\">\n<table class=\"hlh-b6-table\">\n  <thead><tr><th>Mesh Size<\/th><th>Particle Range<\/th><th>\u041f\u0440\u0438\u043b\u043e\u0436\u0435\u043d\u0438\u0435<\/th><\/tr><\/thead>\n  <tbody>\n    <tr><td>4\/8<\/td><td>4750\u20132360 \u00b5m<\/td><td>Heavy paint stripping, wood cleaning<\/td><\/tr>\n    <tr><td>8\/12<\/td><td>2360\u20131680 \u00b5m<\/td><td>General automotive paint stripping<\/td><\/tr>\n    <tr><td>12\/20<\/td><td>1680\u2013850 \u00b5m<\/td><td>Standard aviation cleaning<\/td><\/tr>\n    <tr><td>20\/40<\/td><td>850\u2013425 \u00b5m<\/td><td>Fine parts cleaning, precision cleaning<\/td><\/tr>\n    <tr><td>40\/60<\/td><td>425\u2013250 \u00b5m<\/td><td\">Gem tumbling, electronics cleaning<\/td><\/tr>\n  <\/tbody>\n<\/table>\n<\/div>\n\n<h2 id=\"b6-corncob\">4.

Applications by Industry<\/h2>\n\n<h3>Aerospace &amp; Defense<\/h3>\n<p>Plastic media blasting (PMB) is the standard method for paint stripping military and commercial aircraft without substrate damage. Type I and Type II PBM per MIL-P-85891A are used on aluminum skins, composite fairings, and titanium structural components. The key performance parameter is selectivity: the media must remove the paint film while leaving the bare metal surface dimensionally unchanged within specification.

Unlike chemical stripping (which can leave residues in seams) or heat guns (which risk distorting the metal), media blasting provides complete, uniform paint removal at controlled, low impact energy.<\/p>\n\n<h3>Food &amp; Pharmaceutical Equipment<\/h3>\n<p>Walnut shell and corn cob are the only blast media appropriate for cleaning processing equipment in food, beverage, and pharmaceutical facilities where zero metallic contamination is mandatory. Both materials are GRAS-listed (Generally Recognized As Safe) as agricultural products, and spent media can typically be composted.<\/p>\n\n<h3>Firearms Cleaning<\/h3>\n<p>Walnut shell grit (20\/40 mesh) in a tumbling media application is the standard method for cleaning and polishing firearm brass casings and action components without dimensional impact. The gentle abrasion removes carbon fouling and oxidation while preserving case dimensions critical to safe reloading.<\/p>\n\n<h2 id=\"b6-sourcing\">7.

Thicker or harder epoxy systems may require multiple passes. The key advantage is that while the epoxy is removed, the aluminum substrate beneath is not damaged or dimensionally altered. Always conduct a test panel with your specific coating system and substrate before committing to a full production run.<\/div><\/div>\n<\/div>\n\n<div class=\"hlh-b6-faq-item\" itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\">\n  <div class=\"hlh-b6-faq-q\" itemprop=\"name\">Is walnut shell blast media safe for use around people?<\/div>\n  <div class=\"hlh-b6-faq-a\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\"><div itemprop=\"text\">Walnut shell grit is one of the safest blast media from an inhalation standpoint \u2014 it contains no crystalline silica, no heavy metals, and is composed of natural organic material. However, walnut allergy is a real consideration: workers with tree nut allergies should not handle or be exposed to walnut shell blast media or the resulting dust. In all blast operations, appropriate respiratory protection (minimum N95 for nuisance dust, supplied-air respirator for enclosed applications) is required regardless of media type.<\/div><\/div>\n<\/div>\n\n<\/section>\n\n<div class=\"hlh-b6-cta\">\n  <h2>Find the Right Soft Media for Your Application<\/h2>\n  <p>Contact Jiangsu Henglihong Technology Co., Ltd. with your substrate details, coating system, and performance requirements.
