高くなるので、成形加工が頗る困難となる問題がある。However, since both polyvinylidene fluoride and vinylidene fluoride-67-fluorinated propylene copolymer have high melting points, the resulting composition is difficult to process due to the decomposition of the organic peroxide crosslinking agent contained in the resin. The closer the temperature is to the higher the temperature, the more difficult the molding process becomes.
