Antioxidant DTPD CAS 68953-84-4

What is Antioxidant DTPD CAS 68953-84-4？

Antioxidant DTPD (chemical name: 1,4-benzenediamine, N,N’-mixed phenyland tolyl derivs.) is a highly effective rubber antidegradant widely used to protect rubber products from thermal oxidation, flex cracking, and ozone attack.
This compound belongs to the class of mixed phenyl and tolyl derivs of p-phenylenediamine, offering excellent long-term anti-aging and anti-fatigue performance.

Due to its strong resistance to heat, oxygen, and ozone degradation, Antioxidant DTPD (CAS 68953-84-4) is especially suitable for manufacturing high-performance rubber components that require extended service life and stability under harsh environmental conditions.

สเปค

โปรแกรม

1. Rubber Industry Antioxidant

Antioxidant DTPD is widely used in natural rubber (NR), styrene-butadiene rubber (SBR), butadiene rubber (BR), chloroprene rubber (CR), and EPDM formulations.

It provides outstanding protection against ozone cracking, heat aging, and oxidative degradation, especially in rubber parts exposed to outdoor or dynamic stress conditions.

2. Tire and Conveyor Belt Manufacturing

Extensively applied in tire sidewalls, conveyor belts, hoses, and automotive rubber components, where continuous flexing and high temperatures can accelerate aging.

DTPD enhances fatigue resistance, prevents crack formation, and significantly extends the service life of rubber products.

3. Industrial and Specialty Rubber Products

Ideal for high-temperature rubber sealing materials, rubber cables, and shock-absorbing components.

Compatible with most rubber accelerators and other antioxidants, providing synergistic effects when used in combination.

Advantages of Antioxidant DTPD

• Excellent anti-ozone and anti-aging performance

• Superior heat and fatigue resistance

• Good compatibility with various rubber systems

• Long-lasting protection without significant migration

• Enhances mechanical durability and color stability of rubber compounds
