Molton CS is the standard for stage clothing and is made of the same fabric as backdrops. Molton CS is heavy with a 300 gram/m_ weight.  It has a matte finish and therefore absorbs most of the light. Due to its higher density, it also blocks light much better than Medium Gloss Satin.
Molton CS curtains are washable and flame retardant according to DIN 4102-B1 (IFR).
They are made of 100 % PES FR.
