Electrical Insulation

Protect users and electronics from potential electrical shock and fire

Electronic devices use more power and incorporate more smart internal technologies than ever before. This complexity is designed smaller dimensions further increasing power density with higher voltage components more densely packed together. This creates an immense amount of internal energy that must be isolated to prevent spark voltage between internal components that can lead to device shorting or fire.

Boyd’s dielectric materials are designed as an electrical shield or barrier. These electrically insulating barriers prevent component damage from spark voltage, extend device lifetimes and ultimately maintain safe use environments for consumers. Electrical insulation can be designed from a wide variety of materials into entirely custom configurations to fit seamlessly into your end product. Boyd’s dielectric insulators include UL 94 ratings for vertical and horizontal burn tests helping you pass UL certification and testing. We’re experts in identifying the right raw materials to surpass electrical and flammability requirements and evaluating your product design environment to find efficiencies.

We help you identify complementary components and functionality ideal to integrate into a single component. We often integrate labeling or air baffle components with electrical insulating materials in an electronic enclosure to solve multiple system functions with one deliverable. Server cabinet service instruction labels can be printed on UL 94 rated dielectric insulators to protect the server door from spark voltage of internal cabinet components eliminating the need to source two separate components.
