Flexricin™ Castor Oil Esters Series

Castor Oil alkyl esters are plasticizers for many natural and synthetic resins and elastomers, including polyvinyl chloride, nitrocellulose, ethylcellulose and rubber polymers.

Applications

Flexricin Esters are low-temperature plasticizers for rubber compounds in the production of low durometer stock. 

Flexricin Esters are low volatility plasticizers with excellent electrical insulating properties, superior lubricity and heat stability.

For nitrocellulose, epoxies, and other materials, Flexricin Esters improve cold-crack resistance and impart excellent plate release.

Values shown in the above table are typical properties.

Flexricin P-1 Ester:  Methyl ricinoleate is a low-temperature plasticizer for rubber polymers in the production of low durometer stock. Specific examples include lubricant-plasticizer in phenolic molding resins and a plasticizer for epoxy resin systems.

Flexricin P-3 Ester: Butyl ricinoleate, an outstanding plasticizer for polyvinyl butyral, rosin, vinsol resin, and cellulose acetate butyrate resins. In addition, Butyl ricinoleate is a general purpose plasticizer for both nitrocellulose and ethylcellulose.

Flexricin P-4  Ester: Methyl acetyl ricinoleate is an all-purpose plasticizer for lacquers and vinyls, and a plasticizer and processing aid for low temperature rubber compounds. Flexricin™ P-4 has low volatility and imparts cold crack resistance and plate release to flexible nitrocellulose lacquers.

Flexricin P-6 Ester: Butyl acetyl ricinoleate is a highly efficient plasticizer for nitrocellulose lacquers, imparting good permanence, excellent plate release, cold crack resistance, high gloss and can be used with the polymerized castor oils.

Flexricin P-8 Ester: Glyceryl tri(acetyl ricinoleate) is a very efficient plasticizer having low volatility, excellent electrical properties, extrusion lubricity and heat stability.  Used in vinyl wire jacketing, semi-rigid vinyls, and flexible nitrocellulose lacquers.

Lubricin N-1 Ester: A highly refined methyl ricinoleate for lubricating oils, motor fuels, upper cylinder lubricants, cutting oils and gear oils.  It functions to reduce rusting, corrosion and wear of metal parts and exhibits detergent action on tar, varnish and carbon deposits.
