Abstract: The invention relates to a flame retardant (meth)acrylate composition combining an impact-resistant (meth)acrylic polymer (such as Solarkote® resin from Trinseo) with specific levels of selected organic phosphinate and selected organic phosphorous flame retardants. The composition is halogen free, with superior flame performance, flowability and impact resistance. The composition of the invention is melt-processible and can be co-extruded with a thermoplastic substrate material to obtain a multilayer structure, having a tough, impact resistant cap layer(s). The obtained multilayer structure can be further thermoformed into useful profiles and structures, such as the exterior housing of EV charging stations and car wash stations, automotive applications, aerospace, and building and construction applications.
