Brethyn Gwehyddu Satin Silica Uchel
Cais
Defnyddir y brethyn yn bennaf ar gyfer inswleiddio gwres tymheredd uchel, cadw a diogelu gwres, selio, deunyddiau gwrth-dân ac ati, megis llenni weldio, caeadau tân, blancedi tân, dillad gwrth-dân, llenni inswleiddio gwres, cymalau meddal tymheredd uchel, inswleiddio gwres piblinell stêm, amddiffyniad inswleiddio castio metelegol, gorchudd amddiffynnol ffwrnais ddiwydiannol kiin a thymheredd uchel, inswleiddio tân gwifren a chebl, ac ati.
Defnyddir yn helaeth mewn amddiffyn rhag tân ac inswleiddio gwres o dan amgylchedd tymheredd uchel.
