Rubber Antioxidants
Rubber Antioxidants Manufacturer & Supplier
Rubber antioxidants help protect rubber compounds against degradation caused by heat, oxygen, ozone, light, and repeated flexing. The appropriate grade depends on the rubber polymer, operating environment, required aging resistance, and finished-product appearance.
Heze Great Bridge Chemical Co., Ltd. supplies a range of rubber antioxidants for tire manufacturing and industrial rubber processing. Available grades include 6PPD, IPPD, DTPD (3100), TMQ, ODPA, MB, MMB, MBZ, MMBZ, SP, BHT, and NDBC.
These products serve different formulation requirements.

Choosing Between Key Antioxidant Grades
6PPD: Commonly selected when ozone cracking and flex fatigue are major concerns, particularly in tire compounds.
IPPD: Offers ozone, flex-crack, thermal-oxidative, and light-aging protection. Its staining characteristics should be considered.
DTPD: Used as an antiozonant and antioxidant in tire and industrial rubber compounds. It can be evaluated in combination with 6PPD or IPPD where long-term protection is required.
TMQ: A common choice for heat-aging protection in a range of elastomers.
ODPA: Provides a combination of heat, oxygen, flexing, and ozone protection in suitable rubber systems.

Applications
Tire Manufacturing
6PPD, IPPD, DTPD, and TMQ are relevant grades for tire compounds. PPD-based antioxidants are commonly used to address ozone cracking and flex fatigue, while TMQ supports resistance to thermal-oxidative aging.
Conveyor Belts and Transmission Belts
Antioxidants help protect belt compounds against heat, oxygen, ozone, and repeated flexing. The selection depends on belt construction, rubber formulation, and operating conditions.
Rubber Hoses and Sealing Components
ODPA, TMQ, and other suitable grades can be evaluated for hose compounds, sealing rings, gaskets, and industrial rubber components exposed to heat and environmental aging.
Automotive Rubber Parts
Antioxidants are used in selected formulations for engine mounts, shock absorbers, sealing strips, dust covers, and other rubber components subject to repeated deformation and environmental exposure.
Wire and Cable Products
Suitable antioxidant grades can be incorporated into rubber insulation and sheathing compounds to support resistance to thermal and environmental aging. Polymer compatibility and end-use requirements should be checked before selection.
Rubber Sheets, Shoes, and General Industrial Products
Selected antioxidant grades are used in rubber sheets, rubber soles, industrial seals, and other molded or extruded rubber products. Product selection should account for aging protection, appearance, and formulation compatibility.
Key Formulation Considerations
Ozone and Flex-Crack Resistance: Evaluate 6PPD, IPPD, and DTPD for dynamic rubber products exposed to ozone and repeated deformation.
Heat and Oxidative Aging: Consider TMQ and suitable alternative grades according to polymer type and operating temperature.
Multiple Aging Factors: ODPA can be evaluated where heat, oxygen, flexing, and ozone protection are required.
Staining and Discoloration: PPD-based antioxidants can cause staining. For light-colored or non-staining products, alternative grades should be evaluated through color and aging tests.
Dispersion and Compatibility: Check the interaction between the antioxidant, rubber polymer, fillers, and other compounding ingredients to reduce the risk of poor dispersion or blooming.
