SBS FAF – Fine Powder Elastomer for Bitumen and Polymer Modification SBS FAF (Styrene-Butadiene-Styrene – Fine As Fluff) is a soft, ultra-fine powder elastomer designed for high-efficiency blending in industrial applications. Unlike traditional SBS pellets or regrind, this version is supplied as a light, dispersible powder, offering a high surface area for fast incorporation into target matrices. Thanks to its fine particle size, SBS FAF is ideal for: Bitumen modification in road paving and waterproof membranes, improving elasticity and resistance to cracking. Use as an impact modifier or compatibilizer in styrenic polymers (e.g. PS, HIPS, ABS) to enhance flexibility and shock resistance. Incorporation into plastic or elastomeric compounds where fast dispersion and short processing times are critical. Its powder form ensures rapid mixing and reduced processing time, especially in compounding lines and bitumen tanks. However, it requires attention during handling due to potential dust formation and moisture absorption.
