PET VISCOMETERS MARKET OVERVIEW

The global PET viscometers market size expanded rapidly in 2025 and is projected to grow substantially by 2033, exhibiting a prodigious CAGR during the forecast period.

A PET viscometer is essential in assessing PET's viscosity, which is important for its molecular weight and quality. Earlier, methods such as manual glass capillary viscometers such as Ubbelohde took much time. Newer models of automated differential viscometers include the TESTRON IVS series and PSL Rheotek’s RPV models which provide improved accuracy as they employ the differential pressure across two capillaries to determine viscosity. These modern methods decrease the analysis time, exclude exposure to dangerous solvents and also can analyze other polymers, including the insoluble ones, that is why these systems are beneficial both in scientific investigations of polymers and in the process of quality control in industries.

Intrinsic viscosity (IV) plays a significant role in PET processing since it is directly related to the molecular weight which is related to strength, durability and processability. PET by various applications has different IVs ranging from 0.4-0.7dL/g for textiles, 0.7-0.85dL/g for bottles and 1.0-2.0dL/g for engineering plastics. Automatic PET viscometers can help measure IV constantly and accurately, essential to managing recycled PET material. More advanced tools replace hazardous solvents, making the task less risky and more efficient. These viscometers have the critical function of ensuring rheological quality control of PET so that manufacturers can create substances that exhibit the necessary properties and conform to industry standards.
