Description

2-Ethylhexyl Undecyl Phthalate is a specialized high-molecular-weight phthalate plasticizer. This compound is valued for its excellent permanence and low volatility, providing enhanced durability and performance in demanding polymer applications. It is primarily required by manufacturers in the polymer and specialty chemical industries seeking to improve the flexibility and longevity of high-performance PVC and other resin systems.

Application

• Primary plasticizer for high-temperature and low-volatility PVC applications, including wire and cable insulation.
• Specialty additive for synthetic rubbers and elastomers to enhance low-temperature flexibility.
• Performance additive in sealants, adhesives, and caulking compounds for improved weatherability.
• Plasticizing agent for specialty films and coated fabrics requiring long-term plasticizer retention.
• Functional fluid component in high-performance lubricants and industrial fluids.
• Modifier for nitrocellulose and other specialty lacquers and coatings.
