Description

Butyl Nonyl Phthalate is a high-molecular-weight phthalate ester plasticizer known for its excellent permanence and low volatility. This compound is valued for its ability to impart flexibility, durability, and low-temperature performance to polymer matrices. It is primarily utilized by manufacturers in the plastics, coatings, and specialty chemical industries seeking to enhance the processing and end-use properties of their products.

Application

• Primary Plasticizer for PVC and other polymers requiring low volatility and good resistance to extraction.
• Wire & Cable Insulation formulations to ensure long-term flexibility and electrical properties.
• Coated Fabrics & Automotive Interiors where fogging resistance and durability are critical.
• Sealants and Adhesives to improve flexibility and adhesion over a wide temperature range.
• Printing Inks and Coatings as a resin modifier to enhance film formation and elasticity.
• Specialty Polymer Blends for applications demanding specific migration and compatibility profiles.
