Suspension polymerisation (PVC)

PVC is one of the most commonly used polymers worldwide and has outstanding properties, mainly due to its ability to absorb additives such as plasticisers. In the polymerisation process Tylose® controls the particle size and porosity which is decisive for its additive absorbing behaviour.

 

Tylose® MO grades with a low viscosity level are recommended.

Polymerisation

Polymerisation

In emulsion and suspension polymerisation processes, efficiency combined with a reliable high quality of the resulting product is indispensable. Tylose® acts as highly effective protective colloids in these processes and facilitates outstanding results.
