6PPD Antioxidant and Its Role in Extending Tyre Lifespan Under Stress

6PPD Antioxidant and Its Role in Extending Tyre Lifespan Under Stress

The tyre industry constantly seeks ways to improve durability, performance, and safety of rubber products. One of the key chemicals that contributes significantly to these goals is 6PPD antioxidant. Used widely in the rubber industry, 6PPD protects tyres and industrial rubber products from heat, ozone, and oxidative degradation, thereby extending the lifespan of products under stress.

For manufacturers and buyers looking for high-quality rubber chemicals, understanding the role of 6PPD is critical in selecting the right formulation for tyres, industrial rubber, and other applications.


What is 6PPD Antioxidant?

6PPD (N-(1,3-dimethylbutyl)-N’-phenyl-p-phenylenediamine) is a specialized chemical additive used as a protective antioxidant in rubber compounds. It prevents oxidative and ozone-induced cracking, ensuring tyres maintain elasticity, strength, and performance even under extreme conditions.

Why 6PPD is Essential for Tyres

Tyres are constantly exposed to heat, friction, ozone, and environmental stressors. Without antioxidants like 6PPD, rubber can crack, lose elasticity, and fail prematurely. Using high-quality 6PPD ensures that rubber maintains its mechanical properties, durability, and safety.

Stress FactorEffect on TyresRole of 6PPDOutcome
HeatSoftening or degradationStabilizes rubberMaintains strength and flexibility
OzoneSurface crackingPrevents crackingLonger service life
OxidationLoss of elasticityScavenges radicalsRetains flexibility
Mechanical stressFatigue and wearReinforces polymerReduces failure

Applications of 6PPD in Rubber Chemicals

6PPD is widely used in tyre manufacturing, but its applications extend to industrial rubber products, belts, hoses, and gaskets. Selecting the correct chemical grade ensures optimal protection against environmental and operational stress.

Application TypeRecommended Usage LevelOther Chemicals UsedBenefits
Tyres1–3 phrTMQ, TMTDLong-lasting performance
Industrial Rubber0.5–2 phrMBT, CBSHeat and ozone resistance
Hoses & Belts1–2 phrZinc Oxide, DPGPrevents cracking
Gaskets0.5–1.5 phrRubber antioxidantsMaintains elasticity

How 6PPD Works in Rubber

6PPD acts as a radical scavenger, neutralizing free radicals generated by heat, ozone, and oxidation. This process prevents chain scission in polymers, which directly impacts the lifespan and reliability of tyres and other rubber products.
