Can be used for the production of a variety of bottle grade polyester chips and industrial silk grade chips and other products

  • Solid-phase viscosifying (SSP) process refers to the condensation polymerization of chips in the solid state to increase the molecular weight of the chips and increase the intrinsic viscosity (IV). The process can be used for the production of a variety of bottle grade polyester chips and industrial silk grade chips.
  • Depending on the process, it can be divided into continuous and intermittent.
  • The product obtained by the continuous solid-phase thickening process is stable in quality and less damaged, which is suitable for large-scale production.
  • Intermittent solid-phase viscosified product adjustment is flexible, suitable for small batch production. The small polyester chips are crystallized, dried, tackified and other processes to produce bottle-grade chips; or the large polyester chips are crystallized, dried, tackified and other processes to produce bottle-grade or industrial silk chips.
