Description

Decanedioic Acid 1,10-Bis(1,2,2,6,6-Pentamethyl-4-Piperidinyl) Ester Mixt. With 1-Methyl 10-(1,2,2,6,6-Pentamethyl-4-Piperidinyl) Decanedioate is a high-performance hindered amine light stabilizer (HALS) mixture designed for superior polymer protection. This compound matters because it provides exceptional long-term thermal and UV stability to a wide range of polymeric materials, preventing degradation, discoloration, and loss of mechanical properties. It is essential for manufacturers in the plastics, coatings, and synthetic fiber industries who require reliable stabilization for their products under demanding environmental conditions.

Application

This advanced HALS mixture is utilized across various industries where polymer durability is critical:

• Polyolefin Stabilization: Primary application in stabilizing polypropylene (PP) and polyethylene (PE) against photo-oxidative degradation.
• Automotive Plastics & Coatings: Used in interior and exterior automotive components, under-the-hood parts, and coatings to prevent fading and cracking.
• Industrial & Agricultural Films: Extends the service life of greenhouse films, mulch films, and protective packaging films exposed to sunlight.
• Engineering Plastics: Imparts stability to polymers like polyamides (nylon) and thermoplastic polyurethanes (TPU) used in consumer goods and technical parts.
• Synthetic Fibers & Textiles: Protects fibers from UV-induced strength loss and color change in outdoor applications like artificial turf and geotextiles.
• Adhesives & Sealants: Enhances the weatherability and longevity of polymer-based adhesives and sealants in construction and automotive applications.

Quality Control

Our Decanedioic Acid 1,10-Bis(1,2,2,6,6-Pentamethyl-4-Piperidinyl) Ester Mixt. With 1-Methyl 10-(1,2,2,6,6-Pentamethyl-4-Piperidinyl) Decanedioate is produced under a strict quality management system. The product undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure batch-to-batch consistency and compliance with industry specifications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and physical properties is provided with each shipment to guarantee it meets your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
