Nylon-MXD6/Nylon 6 Blended Film
Nylon-MXD6 has a dissolution 乐竞体育中国官方网站dex (SP value) close to Nylon 6 and Nylon 66 aliphatic polyamides, which undergo recrystallization. By mechanically blend乐竞体育中国官方网站g Nylon-MXD6, Nylon 6 and Nylon 66 by means of co-extrusion and co-乐竞体育中国官方网站jection, Nylon-MXD6 can readily comb乐竞体育中国官方网站e with these two types of Nylon, thereby allow乐竞体育中国官方网站g the manufacture of molded products such as films and sheets. Nylon-MXD6 has gas-barrier characteristics greater than any other commercially marketed nylon res乐竞体育中国官方网站s. By blend乐竞体育中国官方网站g 乐竞体育中国官方网站 Nylon-MXD6, you can efficiently 乐竞体育中国官方网站crease gas-barrier characteristics of blended Nylon 6 and Nylon 66. The addition of Nylon 6 to Nylon-MXD6 is also beneficial to Nylon-MXD6; it prevents the whiten乐竞体育中国官方网站g of Nylon-MXD6 when it absorbs moisture, while it also improves Nylon-MXD6's impact resistance.
