Anotácia

This specification covers glass-fiber reinforced polyester plastic panels intended for use in construction. Light transmitting panels covered by this specification are divided into two types, based on relative response to a laboratory flammability test: Type CC1 for limited flammability and Type CC2 for general purpose. These types may be further subdivided by grades based on relative response to weathering tests: Grade 1 for weather resistance and Grade 2 for general purpose. The polyester resin used in the panels shall be a thermosetting styrenated and acrylated polyester resin composed of polymeric esters in which the recurring ester groups are an integral part of the main polymer chain. The resin shall be reinforced with glass fibers. The polyester resin may contain additives for various purposes. The materials shall be tested for water absorption, tensile strength, linear thermal expansion, and flexural strength.
