3B Fiberglass CM 4020 is a non-woven mat made out of ECR glass _x005F_x001f_laments, consisting of continuous _x005F_x001f_bres randomly oriented in multiple layers. The glass _x005F_x001f_bre is bonded with a silane coupling agent and the layers held together with a suitable binder. The CFM products contain an insoluble binder compatible with both un_x005F_x001f_lled or _x005F_x001f_lled unsaturated polyester, vinyl, ester, epoxy and polyurethane resin systems. The CM 4020 mat is ideally suited for injection molding RTM and S-RIM processes. The CM 4020 mat has a high rigidity which helps to work with large CFM cuts without loosing _x005F_x001f_bres. The ex-cellent mechanical properties provided by CM 4020 combined with the good electrical properties of the resins make the molded parts attractive for applica-tions like the electrical apparatus (high voltage), transportation and automotive industries, infrastructures equipments.
