EXCELCON 417S
EXCELCON 417S is made from high-quality tapioca starch from Thailand through special modification. It can effectively solve the problems such as dusting, low strength, poor workability and low mildew resistance which generally exist in conventional pregelatinized starch. It can also be used in combination with ordinary pregelatinized starch.
