4, the molecular weight is higher than the ordinary packaging beads;
5, sufficient foaming ability, the foaming agent content is generally in 6%~8%, pre-hair multiples in 40~50 times;
6, the moisture content is low, generally less than 1%;
7, the granularity uniformity, concentration;
8, the density is low, the strength and the surface rigidity is good, so that the appearance in the manufacture, the handling and the molding sand filling process is not easy to damage, to ensure the appearance size and shape stability.
