TPV preparation methods are usually three, namely dynamic vulcanization method, physical blending method, latex blending method. The ultimate purpose of the three methods is to obtain the classic "sea-island" structure of TPV. Dynamic vulcanization technology has undergone a long period of evolution, from the early open smelter process to the close smelter process, until the twin-screw continuous vulcanization manufacturing technology. At present, dynamic vulcanization method is widely used in TPV production enterprises at home and abroad, but few enterprises use physical blending method to produce TPV。
