Epoxidized Soybean Oil (ESBO) is a high-quality, bio-based additive widely recognized for its exceptional performance as a plasticizer and secondary heat stabilizer. Derived from natural soybean oil through an epoxidation process, ESBO provides an eco-friendly, non-toxic alternative to traditional stabilizers like heavy-metal-based systems. Its outstanding thermal stability, compatibility with PVC and rubber, and superior resistance to ultraviolet (UV) degradation make it a preferred choice across industries seeking sustainable material solutions.

At A&D Polymers, our ESBO: Quality Stabilizers are engineered to meet the highest industrial standards, offering consistent performance tailored to customer-specific formulations. Whether used alone or synergistically with primary stabilizers, ESBO significantly enhances the durability, flexibility, and safety of final products.

Functional Properties of ESBO: Quality Stabilizers

• Plasticizing Effect: Enhances flexibility and processability in PVC and elastomeric compounds.

• Thermal Stabilization: Protects against degradation during high-temperature processing and prolonged product use.

• UV Resistance: Improves color retention and mechanical properties under UV exposure.

• Eco-Friendliness: Biodegradable and free from heavy metals, aligning with environmental regulations like REACH and RoHS.

• Compatibility: Easily blends with a variety of polymers, including flexible and rigid PVC, nitrile rubber, and polychloroprene.

Areas of Application

ESBO: Quality Stabilizers are used in a broad range of industries, including:

• Automotive: Interior trim parts, under-the-hood components, seals, and gaskets.

• Construction: Flexible PVC sheets, wall coverings, flooring materials, and roofing membranes.

• Packaging: Food-grade containers, cling films, and caps thanks to its non-toxic profile.

• Footwear: Flexible soles and upper components requiring enhanced durability and flexibility.

• Wires and Cables: Insulation layers and sheathing to improve thermal and weather resistance.

• Toys and Childcare Products: Safe, compliant alternatives to phthalate plasticizers.

Key Benefits and Performance Enhancements

• Superior Heat Stability: Extends the life and quality of plastic and rubber products exposed to thermal stresses.

• Enhanced Flexibility: Acts as a secondary plasticizer, improving the softness and pliability of polymers.

• Non-Toxic and Safe: Suitable for sensitive applications such as food packaging and children’s toys, meeting stringent health and safety standards.

• Improved Weather Resistance: Protects products from UV-induced cracking, discoloration, and brittleness.

• Process Efficiency: Facilitates easier molding, extrusion, and calendaring processes by reducing internal friction and processing temperatures.

• Sustainability Focused: Supports green manufacturing practices with its plant-based origin and low environmental impact.
