WEB EXCLUSIVE: Addressing the fast-moving trend toward miniaturization of solar photovoltaic (PV) connectors and junction boxes, SABIC Innovative Plastics, Pittsfield, Mass., has come out with a new resin that enables molding thinner walls and placing conductors closer together. These properties support growing use of solar panels for home use, requiring flatter, unobtrusive designs and integration of components. Lexan EXL 9330S is a new grade of polycarbonate/silicone copolymer facilitates thinner walls with its easy flow and UL 94V-0 flammability rating at 0.8 mm. It also surpasses many other materials in electrical performance, meeting the UL PLC-2 rating for comparative tracking index (CTI). That means it resists arcing in the presence of moisture and salts and thus can be used in parts placed closer together (4 mm vs. 12 mm for Class 3). The copolymer also provides exceptional impact resistance from -40 to +70 C and corrosion resistance for long-term weatherability. It is compatible with alcohol-based sealants and pottants. Its flowability and easy mold release are said to reduce injection molding cycle times by up to 40%.
