Abstract: Mass transit and architectural applications with demanding flame spread and smoke emission requirements represent attractive new markets for composite materials. One route for meeting these demanding requirements is the addition of high loadings of alumina trihydrate (ATH) to modified acrylic resins. Processing challenges for modified acrylic resins with high loadings of ATH have been common. An improved modified acrylic resin has been developed that addresses these processing challenges in pultruding with high loadings of ATH while maintaining excellent flame spread and low smoke emission performance. This paper will compare properties and performance of the new modified acrylic resin with previous modified acrylic resins. Some of the improvements that have been addressed is the stability of the ATH in the resin, the filled viscosity of the resin and increased pultrusion line speed. Several applications of this new resin technology will be discussed during this presentation. A comparison of the previous modified acrylic resins and the new resin will also be compared to show the improvements that have been made. This new system has been tested in ASTM E84 surface burning test as well as in ASTM E162 and ASTM E662 smoke density test to show how it can meet the demanding requirements of mass transit and architectural applications.
