Technip Zimmer Process Technology

Polytrimethylene Terephtalate (PTT)

Technip Zimmer PTT Technology: a proven PTT processTechnip Zimmer’s PTT (Polytrimethylene Terephthalate) technology is a proprietary process developed in the late 90’s in our pilot facilities to satisfy market demand for textile properties. PTT that has new characteristics and excellent performance is mainly used for carpet, textiles and engineering plastics. The start-up of our first commercial scale continuous PTT plant was in Canada in 2004.

Efficient reactor designOur reactors for the PTT process are proven and ensure a long life time of the plant with low maintenance.

The PTT production processOur PTT process is based on 1,3 Propanediol (PDO) and terephthalic acid (PTA) as feedstock. The raw materials are esterified. The final reaction step to reach the desired high viscosity is done in Zimmer’s® Double Drive Reactor (DDR).
