1. Produit bu mag
Ruban graphite bu sell bu kawe, bobine graphite la bu yomba soppiku, ñu defaree ko graphite bu sell bu 99% buñu mëna yaatal, amul lenn luy liant wala luy yàq. Dafay tëye yoonale tàngoor bu baax, yoonale kuuraŋ, ak bañaale tàngoor bu yéeg ci graphite bu sell bu am formu blok, ci noonu muy am flexibilite bu amul benn werante, dëgëraay ci compression, ak yombal liggéey bi. Mën na feesal bërëbi surface yu jaxasoo yi, sos interface thermique bu baax ak ay seal yu wóor yuy tëju.
