Other flame-resistant compounds are available that do not contain halogenated resins. Flammability ratings depend on specific formulations, however, and can vary from 94HB to V-0. Flammability ratings also vary with section thickness. Mineral-filled grades, which can be modified with cellulose to reduce specific gravity and cost, are used in automotive ignition parts, radio and TV components, switchgear, and small appliance housings. Alkyds with all-mineral fillers have high moisture resistance and are particularly suited for electronic components.
Grades are available that can withstand the temperatures of vapor-phase soldering.
