Circularity mark 50/100. Ask which scrap, which certificate, which year. Related atlas entries, a short glossary, and three threads that keep Silk honest.
The filament that stole stockings and chutes. EN 13501-1 reaction-to-fire letter (A1–F), not a wall rating. Thermal conductivity in W/m·K. Lower means better bulk insulation. Declared performance after blowing-agent or moisture drift. The zone where heat or chemistry changes the datasheet.
The label keeps Silk, , and 19. “Pébrine / Pasteur” is the condition on the figure.19
