INTRODUCTION

Blown Castor Oil (15-17 Poise) is a modified grade of Castor oil. The “15-17 Poise” specification refers to its viscosity range, indicating a medium-viscosity blown oil suitable for industrial applications requiring improved body, tackiness, and elasticity compared to regular castor oil.

It offers:

Higher viscosity and better consistency
Improved adhesion and binding properties
Enhanced film-forming capability
Better compatibility with resins and waxes
Good lubricity and plasticizing effect

It is widely used in coatings, inks, sealants, lubricants, and rubber processing.

MANUFACTURE

It is produced by controlled oxidation of refined castor oil.
