Plasticisers are defined as relatively high molecular weight, low volatility, low extractability solvents for polymers. They interact with the polymer, absorbing into and solubilising the polymer and altering the polymer morphology.
Plasticisers are beneficial for various reasons. They can be used to make formulations:
- Softer and more flexible
- Less brittle
- More elastic
- Reduce melting point and melt viscosity
Plasticisation additives include both monomeric and polymeric plasticisers that work to increase the plasticity or fluidity of a polymer. Plasticisers are particularly useful in PVC, but can be used in other polymers such as synthetic rubbers, synthetic rubber derivatives, and other polar polymers such as polystyrene and ABS.

Types of plasticisers by Croda
Monomeric plasticisers due to their small size, offer the benefits of increased physical and mechanical properties through rapid absorption and adsorption to the polymer surface
- Low temperature flexibility
- Low viscosity
- Phthalate free
Polymeric plasticisers offer superior resistance to volatility, migration and weathering over time which is ideal for applications where long-term stability is needed.
- Low extractability (water, oil and detergent)
- Low volatility
- Low migration
We offer a wide range of polymeric and monomeric plasticisers for PVC, and offers many benefits in speciality applications from low temperature environments to food contact.
