 (1) Measure 0.5 grams of polyester in a mixed deep solution of 100 cm3 of phenol and dichlorobenzene (50/50.w/w)
(2) Differential thermal analysis

                                                                     

  Storage stability:

BH-14 can be stored for at least 12 months at room temperature below 25°C under the condition of avoiding direct sunlight and moisture, BH-14 will produce turbidity in solution (a very small amount of cyclic oligomers) ).  

Packaging: Granules packed in paper bags, net weight 25kg.
