Antioxidant DTPD (also known as Antioxidant 3100) is a widely used antioxidant in the rubber industry, mainly used to improve the aging resistance of rubber products. The following are the main applications and characteristics of DTPD in the rubber industry:

1. Ozone resistance and thermal oxidation aging resistance

DTPD has excellent ozone resistance and thermal oxidation aging resistance. It can effectively prevent rubber products from aging due to ozone or thermal oxidation during use and extend their service life.

2. Improve the fatigue resistance of rubber

DTPD can improve the fatigue resistance of rubber, especially suitable for rubber products in dynamic stress environments, such as tires, conveyor belts and shock absorbers. These products need to withstand repeated stretching and compression during use, so they need to have good fatigue resistance.

3. Improve the flexural resistance of rubber

DTPD can effectively improve the flexural resistance of rubber, and is suitable for rubber products that require high flexural resistance, such as hoses, seals and soles. These products are often subjected to external forces such as bending and twisting during use, so it is necessary to prevent cracking caused by flexing.

4. Wide range of applications

DTPD is suitable for natural rubber and various synthetic rubbers, such as styrene-butadiene rubber (SBR), butadiene rubber (BR), chloroprene rubber (CR), etc. It can play an anti-aging role in various rubber products, including tires, hoses, seals, wires and cables, soles, etc.

5. Safety of use

DTPD has low toxicity and good environmental friendliness, and has little impact on the human body and the environment under normal use conditions. This makes it also used in some occasions with high requirements for environmental protection and health.

6. Use with other additives

DTPD is usually used in combination with other antioxidants and antioxidants to achieve better anti-aging effects. For example, combined with 6PPD (anti-aging agent 4010NA) or TMQ (anti-aging agent RD), the anti-aging properties of rubber can be further improved.

In general, the antioxidant DTPD/3100 has become an important additive in the rubber industry due to its good anti-aging properties and wide applicability, especially when manufacturing rubber products that require long-term aging resistance, the application effect is particularly significant.
