BYK MAX SA 4191 is a granulated surface additive used for thermoplastics to increase slip and reduce friction. BYK MAX SA 4191 provides slip and anti-blocking properties when used with polypropylene-based thermoplastics. It reduces friction between materials such as polymers and metals, improving slip performance in a broad range of plastic applications, even at low dosages. BYK MAX SA 4191 provides excellent organoleptic properties, good printability, is non-toxic, and non-corrosive. It is suitable for injection molding, where it can improve demolding and product release. BYK MAX SA 4191 is dust-free, safe, and easy to handle. When used with Advanced Materials, BYK MAX SA 4191 can enhance surface properties, improve processability, and reduce costs by enabling better material release.
