Overview Key Features Typical Applications Technical Information Grades & Supply Safety & Handling Controlled Coating removal WIthout Substrate Damage Type II plastic media removes organic coatings through impact and fracture, not cutting, allowing coatings to be stripped while preserving the underlying surface. Suitable for use in wet or dry blasting systems. Key Features Thermoset urea formaldehyde media Moderate aggressiveness Effective paint and coating removal Minimal substrate damage Suitable for soft metals and composites Typical Applications Automotive paint stripping Coating removal from aluminium Fibreglass and composite cleaning Alternative to chemical stripping Technical Information – Type II Plastic Media Technical Properties Property Typical Value Polymer type Urea formaldehyde Hardness Barcol 54 – 65 (3.5 mohs) Aggressiveness Moderate Particle shape Angular Melting point 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.
