Formulation and qualification notes
Use the published 25–40% addition range as a starting point for trials, not a guaranteed passing dosage. Evaluate carrier compatibility, glass-fiber content, dispersion, processing behavior and mechanical properties together. UL 94 V-0 and 5VA are development targets mentioned for the series; any rating must be verified for the actual compound and thickness. The grade number does not establish a 70% active content.
Packaging and storage
Published packaging: 25 kg bags, with 500 kg or 1,000 kg pallet configurations. Store sealed in a cool, dry place, protected from direct sunlight and moisture.
Request a quotation or technical information
