Epoxidized methyl ricinoleate bio-plasticizer with a
Among numerous bio based plasticizers, epoxidized fatty acid methyl ester, also known as epoxy fatty acid ester, is favorable for application as an additive material in PVC, which...
Preparation of Epoxidized Fatty Acid Methyl Ester with in sit
[en] Epoxidized fatty acid methyl ester (EFAME) is a renewable and biodegradable plasticizer that can be produced from various vegetable oils and even waste oils. In this work, refined soybean oil (RSO) was first converted to fatty acid methyl ester (FAME) by enzymatic transesterification, followed by epoxidation with performic acid in situ generated via auto-catalyzed reaction of formic acid
Design, preparation and characterization of novel toughened
A polymerized fatty acid (PFA) epoxy curing agent was prepared from epoxy fatty acid methyl ester (EFAME) via catalytic ring-opening polymerization and hydrolyzation. Then the novel toughened epoxy asphalt materials with different weight ratios of PFA were prepared.
Conversion of fatty acid methyl ester to epoxy plasticizer by
Fatty acid methyl esters (FAMEs) can be converted to epoxy plasticizer by in situ auto-catalyzed formation of performic acid (PFA) in a bi-phase reaction system. However, mass transfer effect could be neglected in a well-stirred reaction system.

A flexible curing agent, polymerized fatty acid (PFA), was also successfully synthesized through catalytic ring-opening polymerization and epoxy fatty acid methyl ester [30].
- What is epoxy fatty acid methyl ester (efame)?
- Epoxy Fatty Acid Methyl Ester (EFAME) is a versatile, bio-based plasticizer derived from natural oils. It serves as an eco-friendly alternative to traditional phthalate plasticizers, making it an ideal choice for manufacturers and suppliers in the plastic and polymer industries who are focused on sustainability and environmental compliance.
- What is epoxidized fatty acid methyl ester?
- Epoxidized fatty acid methyl ester (EFAME) is a versatile compound with significant applications in various industries, particularly as a plasticizer and stabilizer in polymer production. Its unique chemical properties, including the presence of epoxide rings, make it an effective and eco-friendly alternative to traditional plasticizers.
- What are epoxide groups in efame?
- EFAME contains epoxide groups, which are cyclic ether rings introduced by reacting fatty acid methyl esters with oxidizing agents. This contrasts with general Fatty Acid Esters, which are simply esters formed from fatty acids and alcohols without any specific functional groups. The chemical reactivity of EFAME is also distinct.
- Are epoxy fatty acid methyl esters safe?
- Safety: Epoxy Fatty Acid Methyl Esters (EFAME) should be handled with care to ensure safety. They are generally low in toxicity but can cause irritation. Proper safety measures include wearing protective gloves, goggles, and masks to prevent skin, eye, and respiratory tract contact.
- What is epoxidized fatty acid methyl ester (efame) bio-plasticizer?
- Currently, utilizing unsaturated fatty acid methyl esters to obtain epoxidized fatty acid methyl ester (EFAME) bio-plasticizers constitutes an environmentally responsible solution to substitute conventional ortho-phthalates that are endocrine disruptors or probable carcinogens.
- What is efame used for?
- In the coatings' industry, Epoxidized Fatty Acid Methyl Ester (EFAME) is used as a plasticizer and stabilizer in paints and coatings. As a plasticizer, EFAME improves the flexibility and workability of coatings, allowing for better application and adhesion to surfaces. It enhances the flow properties, which helps in achieving a smoother finish.
