Product Introduction
This product is a bulk molding compound made by using unsaturated polyester resin as a binder, alkali free short cut glass fiber as a reinforcing agent, and adding various components such as fillers, curing agents, release agents, and coloring agents. It not only has high mechanical strength and excellent electrical performance, but also has excellent arc resistance, leakage resistance, and traceability performance that traditional thermosetting materials cannot match. This material also has good formability and is a new material for the replacement of insulation structural components in high and low voltage electrical appliances. BMC-4342 has UL certification.
