Construction Composites
FRP composite materials for construction and civil engineering
Fiber-reinforced polymer (FRP) profiles, gratings, and structural elements for construction rely on UPR and vinyl ester systems processed by pultrusion, RTM, and hand lay-up. Fire retardance is a primary requirement — halogenated and phosphorus-based FR-UPR grades meet EN 13501 and ASTM E84 fire classifications. ATH and magnesium hydroxide fillers provide cost-effective halogen-free flame retardance. Silane coupling agents improve glass fiber/resin interfacial bonding, directly improving mechanical properties of pultruded profiles.
