CINSCOUR® PS is a biodegradable, non-toxic, and non-hazardous detergent designed for the controlled-foam pre-treatment of aramid fibers. It exhibits strong emulsifying properties on oils commonly used in aramid fiber items and can effectively remove fatty derivatives at standard temperatures of 60-70°C, without the need for high heat. Its low foam production makes it suitable for use in a variety of equipment, and it can also be applied in the preparation of threads and yarns. Free from phenol derivatives, chlorinated solvents, or other toxic substances, CINSCOUR® PS is considered easily biodegradable.
