A The Solid State Polymerization (SSP) process refers to the condensation polymerization reaction of solid chips, aiming to increase the molecular weight and intrinsic viscosity (IV). The normal PET Chips are heated to the glass transition temperature (usually 10-40 ° C below the melting point). The small molecular products are taken away by vacuum or inert gas protection (generally using high-purity nitrogen), so the polycondensation reaction is continued and the viscosity is further increased. End Carboxyl (COOH) content can be decreased when IV content is increased. This process can be used to produce various bottle-grade polyester, industrial filament-grade, low-end group content PET chips, etc. 

A SSP machine is a system or a set of devices to realize the condensation polymerization reaction of PET chips by controlling the temperature and vacuum level, or with inert gas flushing, in the envelopped atmosphere of PET materials.  SSP machine can be classified as continuous type or batch type SSP according to the process. usually batch type Solid State Polymerization (SSP) consists of the systems as below:
1. Rotary drum system: used for chip crystallization, drying, and polymerization reactions                           
2. Vacuum system: creating a vacuum inside the rotary drum and removing the by-products of the reaction                   
3. Thermal Oil Circulation System: heating and cooling the materials
4. Electrical Control System: monitoring and recording data. (Advanced software and user-friendly interface design ensure clear and intuitive data display, making it easy to operate.)
