Gas fade resistant stabilizer system for polypropylene fiber
摘要:
Blends of a selected long chain N,N-dialkylhydroxylamine and selected hindered amines are surprisingly effective in providing processing, long term heat aging and light stability performance and especially gas fade resistance to polypropylene fibers in the absence of a traditionally used phenolic antioxidant.
