Overview Key Features Typical Applications Technical Information Grades & Supply Safety & Handling High-Performance Plastic Media for Fast Stripping Melamine plastic media delivers higher impact energy than other plastic types, enabling rapid coating removal while remaining less aggressive than mineral abrasives. Suitable for use in wet or dry blasting systems. Key Features Thermoset melamine media High aggressiveness Fast stripping rates Suitable for robust substrates Typical Applications Heavy paint and coating removal Mould and tool cleaning Industrial stripping applications Technical Information – Type III Plastic Media Technical Properties Property Typical Value Polymer type Melamine Hardness Barcol 64 – 72 (4.0 mohs) Aggressiveness High Particle shape Angular Melting point < 500 °C Specific gravity ~ 1.5 g/cm³ Bulk density ~ 0.65 – 0.75 g/cm³ Suitable systems Wet & dry blast cabinets Compatible with pressure, suction, and cabinet blasting systems. Approvals & Standards Manufactured to MIL-P-85891A Conforms to CSS227 specifications Grades & Supply Multiple particle sizes available Supplied in 25 kg tubs Optional 125 kg drums – Contact us UK stock, 3–5 working day delivery Plastic blast media particle size influences the rate of coating removal and degree of substrate impact. Larger particle sizes increase stripping efficiency, while smaller particles provide greater control and reduced surface stress. Mesh Rating & Approximate Grain Size Mesh Avg. Grain Size (mm) 8/14 1.40 – 2.40 8/16 1.20 – 2.40 8/20 0.80 – 2.40 10/20 0.80 – 2.00 12/16 1.20 – 1.70 16/20 0.80 – 1.20 20/30 0.60 – 0.80 20/40 0.40 – 0.80 30/40 0.40 – 0.60 40/60 0.25 – 0.40 60/80 0.18 – 0.25 80/120 0.12 – 0.18 Particle size selection should be matched to the substrate material, coating thickness, and acceptable surface impact. Softer substrates and thin skins typically require finer particle sizes to minimise damage. Unsure which grit size is right for your application? – Contact usOur technical team can advise on media selection based on substrate, finish, and blasting system. Safety & Handling Plastic media is not considered hazardous under normal use. Potential risks include dust inhalation and skin irritation in sensitive individuals.
