Description

Zinc Dibutyl Bis[[[3,5-Bis(1,1-Dimethylethyl)-4-Hydroxyphenyl]Methyl]Phosphonate] is a high-performance organometallic compound primarily utilized as a synergistic stabilizer and antioxidant in polymer systems. Its value lies in its ability to provide exceptional thermal and oxidative stability, significantly extending the service life of sensitive materials under demanding conditions. This product is essential for manufacturers in the plastics, rubber, and specialty coatings industries who require advanced additive solutions to protect their products from degradation. The compound, identified by CAS NO 10175-95-8, is engineered for reliability in high-temperature processing and long-term outdoor applications.

Application

• Polymer Stabilization: Acts as a highly effective secondary antioxidant and metal deactivator in polyolefins (PP, PE), PVC, and engineering plastics to prevent thermal and oxidative degradation during processing and end-use.
• Rubber Industry: Used as a non-discoloring stabilizer in synthetic rubbers and elastomers to maintain elasticity and prevent cracking caused by heat and oxygen exposure.
• Adhesives and Sealants: Enhances the durability and lifespan of hot-melt adhesives and construction sealants by protecting against heat-induced breakdown.
• Wire and Cable Insulation: Provides critical long-term thermal stability to polymer insulation and jacketing materials, ensuring safety and performance in electrical applications.
• Synergistic Formulations: Often used in combination with primary phenolic antioxidants (e.g., Irganox 1010) and phosphites to create robust stabilization packages with superior performance.
• Specialty Coatings: Incorporated into high-performance coatings to improve resistance to environmental weathering and UV-induced degradation.
