Rubber additive chemical auxiliary anti-aging antioxidants, like phosphites, act as hydroperoxide-decomposing and free-radical-trapping agents, extending the lifespan of rubber products by preventing or slowing down aging. They are particularly useful in polymer systems and don't negatively impact the color or luster of rubber products, unlike some other antioxidants.

Function:
Prevent polymer degradation due to thermal oxidation or photo-oxidation during processing or use, extending material lifespan.
Common Types:
Antioxidants (e.g., BHT, phosphites): Terminate free radical chain reactions to prevent thermal oxidation.
Light stabilizers (e.g., benzotriazole UV absorbers, hindered amine light stabilizers/HALS): Absorb or scatter UV light to reduce photodegradation.
Effect: Maintains mechanical properties (e.g., toughness), prevents discoloration and cracking. Used in automotive parts, packaging materials, etc.
Function:
Prevent coating degradation (chalking, fading) due to UV exposure and oxidation.
Common Types:
UV absorbers (e.g., titanium dioxide, zinc oxide): Reflect or absorb UV rays.
Antioxidants (hindered phenols): Prevent resin oxidation.
Effect: Enhances weather resistance in architectural paints and automotive coatings, maintaining color stability.
Function:
Prevent fiber weakening and discoloration from light and oxidation, extending fabric life.
Common Types:
UV blockers (e.g., titanium dioxide nanoparticles): Reflect UV radiation.
Antioxidant finishes (e.g., plant polyphenols): Inhibit fiber oxidation.
Effect: Used in outdoor apparel and sunshades to preserve strength and color.
Function:
Agricultural films: Delay greenhouse plastic degradation.
Crop stress resistance: Improve plant tolerance to drought and heat.
Common Types:
Light stabilizers (e.g., HALS): Extend the lifespan of PE films.
Natural antioxidants (e.g., salicylic acid, melatonin): Reduce oxidative stress in crops.
Effect: Increases film durability and promotes crop growth under stress.
Function:
Protect solar panel backsheets and cable insulation from environmental damage.
Common Types:
Composite anti-aging agents (antioxidants + light stabilizers): Synergistic protection.
Effect: Ensures long-term stability of energy equipment, reducing maintenance costs.
Anti-aging agents play a crucial role across industries by:
Industrial materials: Extending product lifespan and reducing resource consumption.
Health & wellness: Delaying skin and cellular aging for better quality of life.
Food & agriculture: Minimizing waste and ensuring safety and sustainability.
With technological advancements, anti-aging agents are evolving toward higher efficiency, eco-friendliness, and multifunctionality, promising broad future applications.
Organic materials, both natural and synthetic, are susceptible to oxidation reactions. In the case of polymers, such oxidation reactions are of critical importance, since even very low oxidative conversions of polymers can change many important properties.
For example, if an oxidation reaction causes a linear polymer containing 10,000 units to break its chains, then a conversion of 100X10-6 is sufficient to halve the molecular weight of the polymer. If polymers are oxidized, not only do some of their mechanical properties, such as tensile strength, decrease and their surfaces become roughened, but they can also cause discoloration of the plastic product.
Oxidation can occur at any point in the life cycle of a polymer: during manufacturing and storage, during processing and in the end use of its plastic products. Oxidation is often referred to as an aging phenomenon, while the effects of oxidation on the chemical structure of polymers are collectively referred to as degradation.
Degradation and aging of polymers can be inhibited or delayed, and one way to inhibit or slow down thermal oxidation is to structurally modify the polymer, but by far the most common method is the addition of a suitable stabilizer.
