Castor oil that polymerises through heat and atmospheric oxygen is referred to as ‘blown’ or ‘oxidised castor oil’. The oil becomes more viscous. Controlled oxidation and heating change its chemical properties, resulting in improved stability and greater resistance to oxidation.

Applications known to us are:

Plasticiser for paints and varnishes:

Blown castor oil is used in paint raw materials to increase their elasticity and durability as it is non-volatile and does not migrate.

Leather care:
Blown castor oil is used as a softener, giving the leather a pleasant suppleness and an attractive lustre.

Hydraulic oils:
Thanks to its higher viscosity and stability, blown castor oil is used in special hydraulic oils to improve their performance.

Polyurethane systems:
Blown castor oil is used as a polyol component to optimise the mechanical properties and resilience of the material.

Lubricants:
Blown castor oil is suitable for applications in lubricants that require increased resistance to high temperatures and greater viscosity.

Additive in printing inks and adhesives:

Blown castor oil is used as a thickener and additive to improve the processing properties of printing inks and adhesives.
