Time:May . 11 . 2023 Author:PTSL

SSP Device Name:
SSP - Solid phase viscosity increasing device (Polytex technology, Polytex Design)
Main principle: Solid-phase thickening, also known as solid-phase polycondensation, is a polycondensation reaction carried out in a solid state. Solid polymer particles with a certain molecular weight are heated to a glass transition temperature below their melting point (usually between 10 and 40 ℃ below the melting point), and small molecule products are removed through vacuum or inert gas protection (usually using high-purity nitrogen), allowing the polycondensation reaction to continue and viscosity to further increase.
Device Description:
Intermittent solid phase viscosity increasing device (i.e. drum viscosity increasing, single line capacity: 1-20 tons/batch)
Continuous solid phase viscosity increasing device (single line capacity: 15 tons/day to 750 tons/day)
