What is Epoxy Fatty Acid Methyl Ester (EFAME)?
Epoxy fatty acid methyl ester (EFAME) is a colorless or light yellow transparent liquid. It uses vegetable oil as raw material and can replace primary plasticizers such as DOTP, DOP, DBP, DINP, TBC, DINCH, etc.
Properties:
Epoxy fatty acid methyl ester EFAME
Molecular Formula: C19H36O3
Molecular weight: 312.49
CAS No. 6084-76-0
Material: Plant oil
Characteristics:
It has good lubricity, compatibility and dispersibility, and can be used as a surfactant and dispersant for epoxy coatings and epoxy resins.
Environmental-protection and nontoxic :
Epoxy Fatty Acid Methyl Ester EP619 is made of natural plant oil , it has passed SGS test and conformed to the EU environmental standards .It has been widely used to the disposable PVC gloves which be exported to EU.
Color:
The color of Epoxy Fatty Acid Methyl Ester EP619 reaches at 20(APHA), accordance with the color of DOTP, will not effect any kinds of transparent PVC products.
Epoxy value :
Epoxy value of Epoxy Fatty Acid Methyl Ester EP619 is the highest among the similar products in domestic market.It can increase the substitution quantity to reduce the cost of the PVC products.
No odor :
Through our research and applications for years , Epoxy Fatty Acid Methyl Ester EP619 is odorless ,which improve the quality of PVC products.
Brighter and Softer:
It can make the color of PVC product more vivid , softer and the effect of cold/ heat-resistant more significant by using Epoxy fatty acid methyl ester
Low volatility:
good compatibility, good stability to light and heat, and can reduce the amount of stabilizers.
High efficiency:
The plasticization efficiency is higher than DOP, which can reduce the total amount of plasticizer.

The invention discloses a non-toxic plasticizer of biomass compound epoxy fatty acid methyl ester used in plastics and rubbers processing, which can be represented by the general formula I, wherein R, R' are CnH2n +1 (n = 0~15). The nontoxic plasticizer is prepared with fatty acid methyl ester as raw material, hydrogen peroxide as oxygen body, organic acid as oxygen-carrier, acidic matter as catalyst, and complex as stabilizer through epoxidation. The plasticizer not only has the advantages of excellent toughness, good compatibility, low volatile, small migration, non-toxic, and light and heat stability, but also has superior lubricity, compatibility and dispersibility. It can be used in PVC processing with addition of as many as 5-30%, completely replacing DOP to manufacture nontoxic PVC products for food packaging, medical supplies materials, toys, water supply pipeline, and surfactant, softening agent and dispersing agent used in plastics and rubber industries.
Application:
EFAME has good compatibility with PVC resin. Improve the physical properties of the product, significantly prolong the aging time, and have a good synergistic effect with metal stabilizers such as barium, cadmium, and zinc.
EFAME is widely used in :
PVC calendered film
PVC foamed artificial leather
Clothing leather
Wire and cable
Disposable PVC gloves
Children's toys
Infusion tubes
Medical equipment
Refrigerator seals
Food packaging film
Floor leather
Advertising cloth
Recycled plastic particles
1) 200L drums
2) 1000L IBC Tank
3) 24 CBM Flexitank
4) 25 CBM ISO Tank
