NBR 6240 se yon copolymer de butadiene ak acrylonitrile fabrike pa avanse teknoloji polymérisation emulsion Goodyear ak LG Chem.
NBR 6240 se yon polymère akrylonitrile ki pa tach, mwayen ki ba, ak mwayen segondè ki fèt pou ede nan operasyon pwosesis tankou extrusion ak calen- dering. NBR 6240 se yon tanperati ki ba polymerize polymère, ak tankou, kenbe pwopriyete yo ekselan fizik ak pwosesis nan yon kawotchou nitril frèt. NBR 6240 rekòmande pou itilize nan anbalaj, pwodwi soulye, eponj chimik kònen, pwodwi jaden lwil oliv, pati endistriyèl ak otomobil.
