Solid State Polycondensation(SSP) Device Solid state polycondensation (SSP)is an efficient way to increase the intrinsic viscosity of PET. The PET chips or flakes are transferred to a polycondensation (SSP)reactor, through which the molecular weight of PET rises so that the intrinsic viscosity is increased. Batch Solid State Polycondensation (SSP)Device Capacity: 100T 10000T/Y Advantages: 1. Apply to bottle grade and industrial yarn production 2. Low investment 3. Easy operation 4. Easy adjustment and be flexible for production
