Plasticizers Derived from Vegetable Oils

Contact BMI About This Technology

Technology Marketing Summary

This technology addresses the known health issues of commonly used petroleum-based plasticizers used in polyvinyl chloride (PVC), a high volume thermoplastic material (one that is moldable and formed by heating) by providing a biobased and renewable PVC plasticizer with no known adverse health effects.  These PVC plasticizers are derived from soybean oil, but also can be obtained from other vegetable oils.

Description

Compositions and methods for plasticizing polyvinyl chloride polymers where the plasticizers contain fatty acids derived from vegetable oils and the fatty acids are substantially esterified with an alcohol. The fatty acids having unsaturated bonds that are substantially fully epoxidized, and wherein the fatty acids are added substantially randomly to one or more hydroxyl sites on the alcohol.

Benefits

• Battelle plasticizers are priced similar to commonly used petroleum-based plasticizers such as dioctyl phthalate (DOP), and the price advantage is expected to increase with time as the price of petroleum continues to increase.
• Battelle plasticizers are believed not to have any health issues whereas phthalate-based plasticizers are reputed to be endocrine disruptors.
• Battelle plasticizers have appreciably better exudation than and similar low temperature properties to phthalate plasticizers
• A preferred class of Battelle plasticizers imparts thermal stability to PVC, which is an advantageous property not provided by phthalate plasticizers.

Applications and Industries

• Flexible PVC applications such as tubing, hose, films, sheeting, cable covering, various molded parts, toys

Plasticizers derived from vegetable oils
Compositions and methods for plasticizing polyvinyl chloride polymers where the plasticizers contain fatty acids derived from vegetable oils and the fatty acids are substantially fully esterified with an alcohol (monool or polyol), the fatty acids having unsaturated bonds that are substantially fully epoxidized, and wherein the fatty acids are added substantially randomly to one or more hydroxyl sites on the alcohol. The plasticizers may be added in amounts between about 10 to 230 pph of PVC resin.
