In the processing and long-term use of plastics, oxidative aging is a core pain point restricting the lifespan and performance of products—high-temperature processing easily leads to resin degradation, and outdoor or high-temperature environments can easily cause problems such as embrittlement, cracking, and color deterioration. Antioxidants, as the "anti-aging guardians" of plastics, can inhibit the oxidation chain reaction at its source. Antioxidant 1010, as a benchmark product among phenolic antioxidants, has become the preferred additive in PE, PP, ABS, and engineering plastics fields due to its high efficiency, broad spectrum, and environmentally friendly characteristics. This article will comprehensively analyze Antioxidant 1010 from the dimensions of product essence, core advantages, industry applications, and scientific selection, providing professional reference for enterprises to accurately select materials and enhance product competitiveness.
I. Understanding Antioxidant 1010: Why has it become an industry benchmark?
Antioxidant 1010's chemical name is pentaerythritol tetrakis(β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid), which belongs to the high molecular weight phenolic main antioxidants. Its unique molecular structure endows it with excellent antioxidant properties and compatibility, and it is known as the "king of antioxidants".
1. Core Mechanism of Action: Blocking Oxidative Aging at its Root Cause
The essence of plastic oxidation aging is a free radical chain reaction. Antioxidant 1010 blocks the reaction process through two core functions: first, it actively captures the free radicals generated during oxidation, forms a stable molecular structure, and terminates the transmission and proliferation of free radicals; second, it binds trace metal ions in plastics through chelation, reducing the catalytic acceleration effect of metal ions on the oxidation reaction. This dual protection ensures the anti-aging effect.
2. Core Product Advantages: Key Features Adaptable to Multiple Scenarios
·High efficiency, broad spectrum, and strong adaptability : It can be widely used in almost all thermoplastic plastics such as PE, PP, PVC, ABS, PA (nylon), PC, and EVA, as well as synthetic rubber (SBR, NBR, EPDM, etc.). A single product can meet the anti-aging requirements of multiple types of plastics.
·High temperature stability and excellent migration resistance : Its high molecular weight makes it less prone to volatilization and decomposition in the high temperature environment (160-280℃) of plastic processing, and it has excellent compatibility with resin. It will not migrate or precipitate from the inside of the product during long-term use, ensuring a long-lasting and stable anti-aging effect.
·Environmentally friendly and non-toxic, with high compliance : It is colorless and odorless, and will not pollute the appearance of plastic products. It complies with EU REACH, RoHS and domestic GB 9685 environmental standards, and can be safely used in food contact plastics, medical plastics and children's toys and other scenarios with extremely high safety requirements.
·Synergistic effect and controllable cost : When used in combination with auxiliary antioxidants such as 168 and DLTP, it can produce a significant synergistic effect, with an antioxidant effect far exceeding that of using them alone, and the amount added is extremely low (usually 0.1%-0.5%), which can effectively control the cost of additives while improving the product life.
II. Precise Implementation: Typical Industry Application Scenarios of Antioxidant 1010
Plastic products from different industries have significantly different requirements for processing technology and usage environment. Antioxidant 1010, with its flexible adaptability, has established mature application solutions in several core areas：
1. Packaging Materials Industry: Ensuring Stability in Storage and Transportation
Core requirements: Food packaging, express packaging and other products need to be stored and transported for a long time, are susceptible to aging due to changes in ambient temperature, and must meet environmental and safety requirements;
Application solution: The combination of antioxidants 1010 and 168 can effectively delay the oxidative aging of PE/PP packaging films and food turnover boxes, avoiding problems such as brittleness and yellowing, while meeting food contact safety standards and ensuring the quality of the products inside the packaging.
2. Automotive Plastics Industry: Resisting Aging Under Harsh Working Conditions
Core requirements: Automotive interior parts (dashboard, door panels, seat fabrics) and exterior parts (bumpers, rearview mirror housings) must withstand harsh environments such as high temperature exposure and alternating hot and cold temperatures, and must be resistant to aging, have low odor, and be highly weather resistant;
Application scheme: Interior parts use a combination of antioxidant 1010 and low-odor auxiliary antioxidant to avoid odor generation under high temperature conditions and improve the heat aging resistance of the products; exterior parts are combined with antioxidant 1010 and ultraviolet absorber 326 to resist both oxidation and photoaging, extending the service life of the products by 3-5 years.
3. Electronics and electrical appliance industry: Ensuring long-term work stability
Core requirements: Electronic and electrical appliance housings (ABS/PC material) and cable sheaths (PE/PVC material) need to be used for a long time in the high-temperature environment where electronic equipment operates, requiring temperature resistance, aging resistance, and no impact on electrical insulation performance;
Application solution: Adding antioxidant 1010 can improve the heat aging resistance of products, prevent the outer shell from becoming brittle and the cable sheath from cracking due to long-term high temperature, and ensure the safety and service life of electronic equipment.
4. Agricultural plastics industry: Resistant to strong outdoor ultraviolet rays and high temperatures
Core requirements: Agricultural films, irrigation pipes and other products are exposed to strong ultraviolet rays and high temperatures outdoors for a long time, which makes them prone to rapid aging and degradation. They need to have extremely strong anti-aging durability.
Application scheme: The combination of antioxidant 1010 and ultraviolet absorber 531/327 can extend the service life of agricultural PE film to 2-3 years, effectively resist the degradation and damage of pipes and films caused by ultraviolet rays and high temperatures, and ensure the continuity of agricultural production.
5. Synthetic Rubber Industry: Improving the Service Life of Elastomers
Core demand: Synthetic rubber products (tires, seals, hoses) such as SBR (styrene-butadiene rubber), NBR (nitrile-butadiene rubber), and EPDM (ethylene propylene diene monomer rubber) are prone to loss of elasticity and cracking due to oxidation;
Application: Adding antioxidant 1010 can significantly improve the thermal stability and anti-aging properties of synthetic rubber. For example, its use in EPDM building sealing strips can extend the dynamic fatigue life by more than two times, and its use in NBR oil-resistant hoses can improve heat resistance and extend service life by about 50%.
III. Scientific Selection and Use: Key Considerations for Antioxidant 1010
The proper selection and use of antioxidant 1010 can maximize its anti-aging effects while controlling costs. The following key points should be considered :
·Match the processing technology and control the timing of addition : Antioxidant 1010 should be added as early as possible during the melting stage of plastic resin to ensure that it is evenly dispersed in the resin; if the processing temperature exceeds 260℃, it is recommended to appropriately increase the amount added, or to compound it with 168 to enhance high temperature stability.
·Adjust the formula according to the usage environment : products used outdoors need to be combined with ultraviolet absorbers, products used in high-temperature conditions can appropriately increase the amount added, and food contact grade products must strictly control the amount added within the compliant range.
·Avoid mixing with antagonistic substances : It is not advisable to mix with sulfur-containing rubber accelerators, heavy metal stabilizers, etc., so as not to affect the antioxidant effect; if it is necessary to use it with other additives, it is recommended to conduct small-scale tests to verify compatibility first;
·Preferred choice : Antioxidant 1010 alone is suitable for simple working conditions. For complex environments (high temperature, outdoor, long-term use), it is recommended to use the 1010+168 compound system to achieve synergistic effect while reducing the amount of single additives and improving cost-effectiveness.
Choosing a high-quality antioxidant 1010 is key to extending the lifespan of plastic products, ensuring product quality, and enhancing market competitiveness.
