At Hie Plastic, we supply Antioxidant 1010 to a diverse range of industries because it serves as a highly effective Polymer Thermal Stabilizer. Its chemical structure allows it to be compatible with numerous organic substrates, providing long-term protection without negatively impacting the material’s physical properties. Whether you are manufacturing basic packaging films or high-performance industrial parts, this additive is a staple in modern formulation.

Use in Polyolefins (PE, PP, Polybutene-1)

This product is widely recognized as a standard PP/PE Processing Stabilizer. We see extensive application of Antioxidant 1010 in the production of polyolefins, specifically Polyethylene (PE), Polypropylene (PP), and Polybutene-1.

• Thermal Protection: It protects the resin against thermo-oxidative degradation during high-temperature processing steps like extrusion and molding.
• Color Retention: It helps maintain the original color of the polymer, preventing yellowing in the final product.
• Durability: It extends the service life of the plastic by inhibiting chain scission and cross-linking.

Application in Engineering Plastics

Beyond standard plastics, Antioxidant 1010 is essential for engineering plastics that require higher durability and resistance to harsh environments. Our clients frequently utilize it for:

• Polyacetal (POM): Ensures stability during molding.
• Polyamide (PA): Protects nylon-based materials from heat aging.
• Polyurethane (PU): Prevents degradation in foams and elastomers.
• Other Resins: It is also effective in Polycarbonate (PC) and polyesters, offering excellent extraction resistance.

Elastomers, Adhesives, and Synergistic Blends

The versatility of this hindered phenolic antioxidant extends to synthetic rubbers and adhesive formulations. It is highly effective in ABS (Acrylonitrile Butadiene Styrene) and SBS elastomers, ensuring the material remains elastic and does not become brittle over time.

For manufacturers looking to maximize performance, Antioxidant 1010 is often used as part of a Synergistic Antioxidant Blend.

• Combinations: It works exceptionally well when blended with secondary antioxidants like phosphites (e.g., Antioxidant 168) or thioesters.
• Adhesives: It provides stability to hot-melt and solvent-based adhesives, preventing skinning and viscosity changes.
• Performance: The combination creates a robust defense system against both processing heat and long-term environmental aging.

Solubility and Physical Properties

Solubility Profile in Organic Solvents

Understanding how an additive interacts with solvents is critical for effective compounding. Antioxidant 1010 is engineered to integrate seamlessly into organic substrates. It exhibits excellent solubility in common industrial solvents such as benzene, acetone, and chloroform. Conversely, it is insoluble in water and only slightly soluble in alcohol. This specific solubility profile ensures that the stabilizer integrates well during manufacturing but does not leach out easily when the final product is exposed to aqueous environments.

Molecular Weight and Migration Resistance

The durability of this stabilizer is largely due to its chemical structure. As a High Molecular Weight Antioxidant (approximately 1178 g/mol), it provides superior resistance to migration and extraction compared to lighter phenolic antioxidants. This high molecular weight ensures the additive stays locked within the polymer matrix, offering long-term protection against thermo-oxidative degradation without blooming to the surface.

Key Physical Data:

• Appearance: White powder or granular form
• Melting Point: 110.0 – 125.0 °C
• Volatiles: ≤ 0.5%
• CAS Number: 6683-19-8

We prioritize these physical specifications to guarantee low volatility and high color stability, ensuring the material performs reliably even during high-temperature processing.

Handling, Storage, and Safety (SDS)

To get the best performance out of Antioxidant 1010, proper handling is non-negotiable. While this hindered phenolic antioxidant is known for its high stability and low toxicity, maintaining its integrity during storage is key to ensuring it works effectively in your polyolefin or engineering plastic applications. We prioritize safety and quality, ensuring that the material reaches you in optimal condition, but once it is in your warehouse, following these protocols is essential.

Proper Storage Conditions for Shelf Life

Moisture and heat are the main enemies of chemical additives. To maintain the shelf life and effectiveness of the product, we recommend the following storage practices:

• Cool and Dry: Store the material in a cool, dry, and well-ventilated area. Avoid direct sunlight and high-temperature zones.
• Sealed Containers: Keep the packaging—typically our standard 20kg or 25kg bags/cartons—tightly closed when not in use. This prevents contamination and moisture absorption.
• Incompatibility: Store away from strong oxidizing agents to prevent potential chemical reactions that could degrade the stabilizer.

Safety Precautions and PPE Recommendations

Although Antioxidant 1010 is odorless, tasteless, and exhibits low toxicity, standard industrial hygiene should never be overlooked. Always refer to the Antioxidant 1010 SDS (Safety Data Sheet) for comprehensive safety data.

• Respiratory Protection: Since the product comes in powder or granular form, use a dust mask or respirator if your feeding process generates dust.
• Protective Gear: Wear safety glasses and gloves to avoid direct contact with eyes and skin.
• Hygiene: Wash hands thoroughly after handling the material and before eating or drinking.
