1, the use of advanced equipment, with solid phase increased bonding process, PET monomer molecules in ethylene glycol and terephthalic acid molecules condensed together in solid state to form a long chain polymer, greatly improving the viscosity. 2. After solid phase viscosification,PET particles have high viscosity, increased tensile strength and good toughness.
3, according to customer demand can increase the original slice and regenerative slice, viscosity reaches 1.0al/g or more. 4, the color is white, green, black, blue.
