A clear, water-based flame retardant treatment for fabric and natural fibre textiles — trusted in South Africa since 1975, with test evidence going back to 1973.
Sapphire Flame Retardant's effectiveness was first independently verified in 1973 by the National Building Research Institute of the CSIR. Fifty years later, Firelab — based on the same CSIR campus in Pretoria — confirmed the same performance under the current SANS 10177 – Part 9 protocol: no flame spread, and self-extinguishing behaviour within 24 seconds of flame removal on treated 240gsm cotton.
240gsm cotton, treated, tested under SANS 10177 – Part 9.
