Improving the Electrical Property of Laminates | Plastics | Engineering

Electrical properties of laminates, especially moulded premix parts prepared from polyester resins, can be significantly improved by the judicious selection of inert fillers to be incorporated into the system. In general, the electrical properties will improve as the filler content of a product is increased. Therefore, it is most practical to use the highest possible amount of fillers of the [...]
