Description

Antioxidant 1726 is a high-performance, hindered phenolic antioxidant widely recognized for its exceptional efficacy in protecting polymers and other organic materials from thermal and oxidative degradation. Its primary value lies in extending the service life and maintaining the physical properties of finished products under demanding conditions. This additive is essential for manufacturers in the plastics, rubber, and synthetic fiber industries seeking to enhance the durability and color stability of their materials.

Application

• Polyolefin Stabilization: Primary antioxidant for polypropylene (PP) and polyethylene (PE) resins, including HDPE, LDPE, and LLDPE, to prevent chain scission and embrittlement during processing and end-use.
• Engineering Plastics: Critical additive in polyamides (nylon), polyesters (PET, PBT), and styrenics (ABS, PS) to maintain mechanical strength and prevent yellowing.
• Synthetic Rubber & Elastomers: Used in SBR, BR, NBR, and EPDM to protect against heat aging and ozone attack, preserving elasticity and tensile properties.
• Adhesives & Sealants: Incorporated into hot-melt and reactive adhesive formulations to prevent gelation and maintain bond strength over time.
• Thermoplastic Elastomers (TPEs): Stabilizer for TPO, TPV, and SBS-based compounds to ensure long-term performance in automotive and consumer applications.
• Masterbatch Production: A key active component in antioxidant and additive concentrates for simplified and precise compounding.
• Lubricants & Greases: Antioxidant for synthetic and mineral-based lubricating oils and greases to inhibit sludge formation and viscosity increase.
