RUBBER PROCESSING ANTIOXIDANTS & ACCELERATORS
Above Infinity demonstrates meticulous sourcing practices for antioxidants. Their commitment begins with collaborating closely with trusted suppliers who provide high-quality phenolic compounds (such as 6PPD and TMQ) and amine-based antioxidants (such as MB and DPPD).
These antioxidants play a crucial role in extending the service life of rubber products by preventing surface cracking and degradation due to heat, light, and oxygen exposure.
The company’s expertise extends to accelerator sourcing. They carefully select accelerators based on their specific applications.
Proper accelerator selection ensures optimal curing and enhances mechanical properties in the final rubber products.
Rubber Accelerator TMTD (Tetramethylthiuram Disulfide)
TMTD is a highly effective rubber accelerator known for its ability to significantly enhance the vulcanization process. It is a white or light yellow powder that is soluble in benzene, acetone, and carbon tetrachloride.
Chemical Formula: C₆H₁₂N₂S₄
Melting Point: 142-147°C
Boiling Point: 305°C
Density: 1.37 g/cm³
Applications: TMTD is widely used in the production of various rubber products, including tires, hoses, belts, and seals. It is particularly effective in accelerating the vulcanization of natural rubber and can also be used with other elastomers such as styrene-butadiene rubber (SBR) and nitrile rubber (NBR). TMTD is known for its fast curing speed and excellent scorch resistance
Rubber Antioxidant TMQ
TMQ is a versatile rubber antioxidant that significantly improves the heat resistance and aging properties of rubber products. It is a highly effective additive that helps prevent the degradation of rubber by reacting with oxygen and other reactive substances.
Chemical Formula: (C₁₂H₁₅N)ₙ
Molecular Weight: 173.26 g/mol
Applications: TMQ is used in a wide range of rubber products, including tires, hoses, belts, and seals. Its effectiveness is not limited to a specific type of rubber, making it a popular choice among rubber manufacturers. TMQ helps to extend the service life of rubber products by neutralizing the harmful effects of oxygen and other reactive substances, thereby slowing down the aging process.
Rubber Antioxidant IPPD (4010NA)
IPPD is a high-activity antioxidant that provides powerful antiozonant and antioxidant properties. It offers excellent high-temperature, fatigue, and flex resistance to rubber compounds.
Chemical Formula: C₁₅H₁₈N₂
Molecular Weight: 226.32 g/mol
Applications: IPPD is primarily used in pneumatic tire components, solid tires, belts, hoses, cables, automotive mounts, bushings, and general mechanical products. It is particularly effective in protecting rubber compounds from ozone and oxidative degradation. IPPD is more active than quinoline or diphenylamine-based antioxidants and provides compound protection against catalytic degradation by copper and other heavy metals.
