Emulsion Polymerisation

Requirements:

High local forces lead to coagulation of E-polymerisates and therefore to bad qualities (picture left on the top). An uniform blending is achieved with the two-stage EKATO-INTERMIG (picture left at the bottom). Further design conditions are:

• High viscosities up to 130,000 mPas
• Diameter ratio d/D up to 0.95
• Short batch cycles
• High heat transfer coefficients

Typical applications:

Polybutadienlatex: (PBL), Styrene-Acrylnitril-Copolymerisates (SAN), Styrene-Butadien-Rubber (SBR) and Styrene: Impellers like the helical ribbon or the EKATO PARAVISC acting close to the wall are optimum for these applications.
