SCONA TSPP 10213 GB is a highly effective adhesion promoter based on a polypropylene functionalized with maleic acid anhydride. SCONA TSPP 10213 GB improves the mechanical properties and adhesion of filler, glass fiber, carbon fiber and natural fiber compounds as well as one packs in polypropylene. It is suitable for use in polypropylene compounds with short and long glass fibers as well as natural and carbon fibers. Furthermore, it is also suitable for fillers such as ATH, Mg(OH)2, CaCO3, even at low dosage. SCONA TSPP 10213 GB additionally improves the mechanical properties of these compounds, especially in polypropylene/natural fiber compounds. Here it also reduces water absorption. In its supplied form (granulate), the modifier is highly suited to producing one packs and masterbatches. SCONA TSPP 10213 GB provides enhanced adhesion and mechanical properties which results in durable, long lasting products for infrastructure and construction applications.
