== Substitutes ==
Some lightweight [[aggregate (geology)|aggregates]], such as [[diatomite]], [[perlite]], and [[vermiculite]], may be substituted for ground mica when used as filler. Ground synthetic ''fluorophlogopite'',<ref>{{cite web|url=https://www.continentaltrade.com.pl/fluorphlogopite-synthetic-mica|title=Fluorphlogopite – synthetic mica – Borosilicate and quartz glass, mica, sealing, level gauges, armature – Continental Trade.|website=www.continentaltrade.com.pl|url-status=live|archive-url=https://web.archive.org/web/20180212083504/https://www.continentaltrade.com.pl/fluorphlogopite-synthetic-mica|archive-date=2018-02-12}}</ref> a fluorine-rich mica, may replace natural ground mica for uses that require thermal and electrical properties of mica. Many materials can be substituted for mica in numerous electrical, electronic, and insulation uses. Substitutes include [[acrylate polymer]]s, [[cellulose acetate]], [[fiberglass]], [[fishpaper]], [[nylon]], [[phenolic resin|phenolics]], [[polycarbonate]], [[polyester]], [[styrene]], [[polyvinyl chloride|vinyl-PVC]], and [[vulcanized fiber]]. Mica paper made from scrap mica can be substituted for sheet mica in electrical and insulation applications.<ref name=usgs2/>
