2. Fiil kuuraŋ yuñ defaree plastik: Fiil kuuraŋ yu am couche isolé plastik buñ extrudé. Plastik yiñ gëna jëfandikoo ñooy chlorure de polyvinyl, poliéthylène ak poliéthylène buñ lëkkale. Fiil plastik yi dañu am jëmmal bu yomb, yombal defar ak jëfandikoo, yomb nañu, te yomb nañu samp ak tëral te duñu am benn yamaleg kawewaay. Moo tax ñu bari dañu leen di jëfandikoo ci fiil yu am voltage bu digg ak bu woyof, te ñu ngi jëm ci wecci fiil yi am diwu viskoz-impregné ci këyit.
