Applications of Anti-aging Agent in Industrial Manufacturing

The anti-aging agent developed by our company serves as a critical raw material in several manufacturing sectors where oxidative, thermal, and photodegradation pose challenges to product durability and safety. Here we present real-world application scenarios, specific industry standards, formulation ratios, process steps, and finished products supported by our production and technical experience.

1. Polyolefin Plastics (Polyethylene & Polypropylene) Processing

In the polyolefin sector, manufacturers rely on our anti-aging agent to suppress oxidation and polymer chain scission during both polymerization and downstream extrusion steps. Protection at elevated temperatures and under exposure to sunlight extends the service life of molded, extruded, or blown products used in packaging, pipes, and industrial films.

Industry compliance standards

• EN ISO 11357 (Thermal Analysis of Polymers)
• FDA 21 CFR 177.1520 for food contact polymers
• GB/T 19466 (Chinese standard for plastic stability)
• REACH Regulation (EC) No 1907/2006

Typical usage ratio

• 0.1%–0.5% w/w based on polymer mass. Precise dosage adjusts according to expected exposure to heat, light, and processing duration.

Downstream process integration

• Dosed into resin at compounding or masterbatch stage prior to extrusion or molding. Integrated directly via automated feeder or gravimetric dosing.

Final product types

• Disposable and reusable packaging film
• Plastic pipes for water and gas distribution
• Automotive plastic components
• Household storage containers

2. Synthetic Rubber Compounding (Automotive and Industrial Rubber Goods)

Rubber processors use our anti-aging additive to protect butadiene, isoprene, and natural rubber blends from cracking, hardening, and ozone damage. This improves service intervals and product resilience in tires, gaskets, and vibration components subjected to dynamic loading and environmental wear. Our product consistently meets rigorous longevity targets under cyclic stress, humidity, and temperature extremes.

Industry compliance standards

• ASTM D2000 (Rubber Products Specification)
• ISO 9001:2015 (Quality Management for Rubber Processing)
• GB/T 2941 (Rubber Sample Preparation & Conditioning)
• ECHA SVHC (Substances of Very High Concern) limitations

Typical usage ratio

• 1–2 phr (parts per hundred rubber). Exact ratio depends on base polymer, filler system, and required ozone resistance level.

Downstream process integration

• Introduced into the internal mixer along with elastomer, carbon black, and process oil. Homogenized before addition of vulcanization chemicals.

Final product types

• Passenger and commercial vehicle tires
• Automotive hoses, seals, and gaskets
• Industrial conveyor belts
• Rubber bushings and vibration isolators

3. Lubricating Oil and Grease Formulation

Producers of automotive and industrial lubricants incorporate our anti-aging additive to minimize oxidative degradation in mineral and synthetic base oils. The additive stabilizes viscosity and acid number during extended service, even under high-temperature or high-shear conditions. Strong performance under ASTM oxidation tests assures suitability for both engine oils and specialty greases.

Industry compliance standards

• API SN/CF (Engine Oil Performance)
• ASTM D2272 (Oxidation Stability of Lubricating Oils)
• DIN 51517 (Industrial Lubricating Oils)
• ISO 21469 (Safety of Machinery Lubricants for Food Processing)

Typical usage ratio

• 0.2%–1.0% w/w, determined by base oil type and application (e.g., engine, hydraulic, or food-grade grease). Higher in extreme pressure or high-temp blends.

Downstream process integration

• Blended into base oil during the additive package mixing step, prior to final filtration and packaging. Compatible with blending at both ambient and elevated temperatures.

Final product types

• Passenger car and heavy-duty engine oils
• Industrial hydraulic fluids
• Multipurpose and high-temp greases
• Compressor and gear oils

4. Coating and Paint Formulation (Architectural, Industrial, Automotive)

Paint and coating formulators utilize our anti-aging agent in waterborne, solvent-based, and powder coatings to combat discoloration, loss of gloss, and chalking caused by UV rays, heat, and atmospheric oxygen. This supports longer protection intervals for steel, wood, plastics, and construction materials exposed outdoors or under direct sunlight. Effectiveness verified via accelerated aging and weathering test systems.

Industry compliance standards

• ISO 12944 (Corrosion protection of steel structures by protective paint systems)
• ASTM D4587 (UV Exposure of Paints and Coatings)
• REACH compliance for paint additives
• RoHS Directive on hazardous substances

Typical usage ratio

• 0.3%–1.2% w/w on total binder solids. The dosage adjusts with pigment load, film thickness, and outdoor exposure class.

Downstream process integration

• Dispersed into the millbase or let-down varnish during high-shear mixing. Can be post-added to finished paint or during tinting for specialty batches.

Final product types

• Protective metal and concrete primers
• Automotive OEM and refinish coatings
• Architectural exterior paints
• Industrial equipment coatings

5. Adhesive and Sealant Production (PU, Epoxy, and Silicone Systems)

Manufacturers of adhesives and sealants add our anti-aging ingredient to preserve polymer integrity in moisture-curing, heat-curing, or UV-curing products. This application is essential in construction, electronics, and automotive assembly where adhesive joints must maintain bond strength and flexibility over time under dynamic loads, vibration, and varying climates.

Industry compliance standards

• ISO 11600 (Classification of Sealants for Building Construction)
• ASTM C920 (Specification for Elastomeric Joint Sealants)
• UL GREENGUARD Certification (Low Emission Adhesives)
• Directive 2004/42/EC (VOC limit for adhesives/sealants in Europe)

Typical usage ratio

• 0.2%–0.8% w/w. Adjusts based on adhesive polymer type, exposure conditions, and required storage stability.

Downstream process integration

• Added during prepolymer blending or during final compounding before packaging. Incorporates efficiently with common mixing and degassing equipment.

Final product types

• Structural construction adhesives
• Automotive assembly sealants
• PU and silicone glazing sealants
• Electronics encapsulation adhesives

6. Fiber and Textile Manufacturing (Synthetic Fiber Production)

Synthetic fiber producers use our anti-aging chemical during the polymer spinning or dope preparation stage. The purpose is to inhibit thermo-oxidative degradation that would otherwise compromise tensile properties and colorfastness in applications such as carpets, upholstery, technical textiles, and geotextiles.

Industry compliance standards

• ISO 105-B02 (Color Fastness to Artificial Light)
• GB/T 23344 (Polyester Fiber Stability)
• REACH SVHC limitations for chemical used in textiles

Typical usage ratio

• 0.1%–0.4% w/w in relation to total polymer. Dosage varies with fiber denier, process temperature, and post-processing steps.
