Phenolic resin manufacturing

Polymerization Application - Viscosity solutions for phenolic resin processes

 

Viscosity is an indirect means of measuring the molecular mass of polymers. Phenolic resins have exothermic reactions. They are very sensitive to temperature, and viscosity value requires observation.

If the reaction occurs too quickly, the result is poor polymer quality and / or hardening. This causes huge raw material losses, extensive downtime for complicated maintenance, increased labor overhead, and delivery delays. Sometimes it requires equipment replacement at enormous costs.

Viscosity related issues in batch process polymerization are: raw materials control, reaction start detection, polymerization speed control, molecular weight measurement, chain length characterization, reaction end-point detection, polymer dilution control, concentration, and finished product quality control.

Key product characteristics

  • Good sensitivity at low viscosity
  • high full scale range

The installation of a MIVI sensor with alarms on a phenolic resin reactor batch process provided increased protection which avoided hardening issues. In addition, it reduced solidification to zero.

The savings realized after installing of a MIVI process viscometer in a phenolic resin batch polymerization factory provided ROI in approximately 1 year.
