Epoxidized Soybean Oil—A Little Helper in Plastic Processing

Epoxidized soybean oil (ESO) is a non-toxic, odorless plasticizer and stabilizer synthesized from soybean oil through epoxidation. ESO is mainly used as a plasticizer to improve the processing performance and physical properties of polymers, such as plastics and rubber.

1. Improving Flexibility: ESO increases the distance between polymer molecular chains and reduces the intermolecular interaction force, thereby enhancing the flexibility, ductility, and fluidity of the material. This characteristic of ESO can significantly improve the softness of PVC plastics, making them easier to process and form.

2. Enhancing Ductility: When plastic products are stretched, ESO helps to increase the ductility of the material, reduce breakage caused by stress concentration, and improve the impact resistance and low-temperature performance of the material. Therefore, ESO is often used in the manufacture of some polyolefin products that require flexibility and low-temperature resistance, such as agricultural films and anti-cold modification of plastic pipes.

3. Improving Demolding Performance: ESO reduces the viscosity and melting point of polymers, making plastics easier to form during processing. Moreover, ESO can form a lubricating film between the plastic and the mold surface, reducing the friction between the plastic and the mold, making the product easier to demold and reducing deformation and damage during demolding. Therefore, using ESO can increase processing efficiency and product quality.

4. Optimizing the Appearance of Plastic Products: ESO helps to reduce internal stress during plastic processing, avoiding defects such as warping, shrinkage, and cracking in plastic products. Using ESO can make the finished surface smoother and more uniform.

5. Enhancing Light Stability: ESO has a certain ability to absorb ultraviolet rays. ESO can absorb some ultraviolet rays, reducing the damage to plastic molecules by ultraviolet rays and improving the light stability of plastics. For plastic products used outdoors, such as plastic doors and windows, outdoor furniture, and automotive interior parts, adding ESO can effectively slow down the aging speed of plastics.
