AT1010 Primary Antioxidant for Long-Term Thermal & Oxidation Stability in PVC / PE

• Product Overview:
AT1010 appears as white powder with high purity and excellent thermal resistance. It features a melting point of 183–187℃ and light transmittance ≥95% at 500nm, ensuring minimal impact on product color and clarity.

• Function Mechanism:
The primary antioxidant neutralizes free radicals formed during high-temperature processing, preventing chain scission, discoloration, and mechanical property deterioration. AT1010 works synergistically with secondary antioxidants to provide comprehensive protection.

• Processing Performance:
With main content ≥94% and low volatile content (≤0.5%), AT1010 exhibits excellent stability under extrusion and injection molding conditions. Its uniform dispersion ensures consistent antioxidant performance across batches.

AT1010 is ideal for manufacturers seeking enhanced thermal stability, long-lasting oxidation resistance, and extended service life for PVC and PE products.

Packing: 25kg/bag
Storage: Store in a cool, dry and well-ventilated warehouse.
Shelf Life: 2 years under proper storage conditions
Note: Keep away from moisture, heat and direct sunlight. Avoid contact with strong oxidizing agents.

1. Long-Term Thermal Stability

AT1010 primary antioxidant provides outstanding protection against thermal degradation, ensuring polymers maintain mechanical and physical properties during processing and long-term use.

2. Excellent Oxidation Resistance

Effectively neutralizes free radicals generated in PVC and PE systems, preventing chain scission and oxidative yellowing.

3. Synergy with Secondary Antioxidants

When used with secondary antioxidants like AT168, AT1010 delivers enhanced and sustained polymer stabilization, prolonging service life and product reliability.

4. Color Protection & Transparency

With high light transmittance (≥95% at 500nm), AT1010 preserves polymer clarity and prevents discoloration during extrusion, molding, and long-term heat exposure.

5. Low Volatility & High Purity

Low volatile content (≤0.5%) ensures minimal loss at high processing temperatures, maintaining consistent antioxidant performance.

6. Solves Manufacturer Pain Points

AT1010 prevents issues like surface defects, discoloration, viscosity loss, and premature aging, improving production efficiency, product quality, and customer satisfaction.

• PVC Pipes & Profiles – Enhances thermal stability during extrusion, maintaining mechanical integrity and appearance.
• PE Films & Sheets – Provides long-term oxidation resistance, ensuring durability for packaging and construction applications.
• Cable & Wire Insulation – Protects polymer insulation from thermal and oxidative degradation.
• Injection Molded Products – Maintains polymer chain stability during high-temperature processing, extending product lifespan.

AT1010 primary antioxidant is suitable wherever PVC or PE products require long-term thermal stability, oxidation resistance, and color retention.
