Common problems of rubber products

Rubber products often face the problem of ozone aging and thermal oxidative aging during use. This will not only lead to a decline in product performance, but also affect its service life and safety. Ozone and oxygen are the main factors causing rubber aging, which will corrode the chemical structure of rubber molecules, causing the material to become brittle, crack and lose elasticity.

IPPD's Solution

As an antioxidant widely used in the rubber industry, IPPD (N-phenyl-N'-isopropyl-p-phenylenediamine) exhibits excellent resistance to ozone aging and thermal oxidative aging. IPPD reacts with active groups in rubber molecules to form stable chemical bonds, preventing ozone and oxygen from corroding rubber molecules. Specifically, IPPD can capture free radicals and slow down the rate of rubber oxidation degradation, thereby extending the service life of rubber products.

How it works

The working principle of IPPD mainly includes two aspects: first, it can effectively capture free radicals, prevent free radical chain reactions, and reduce rubber degradation; second, it reacts with ozone and oxygen molecules to generate harmless compounds to avoid further damage to rubber molecules. Data shows that rubber with an appropriate amount of IPPD can maintain an elongation of up to 30% in an ozone and oxygen environment, while rubber without IPPD has an elongation of only 10%.

Application Examples

IPPD plays a key role in rubber products in many fields.

Automobile tires: In automobile tires, IPPD not only extends the service life of the tires, but also improves reliability under various road and climate conditions. Data shows that the service life of tires treated with IPPD can be extended by more than 20%.

Industrial adhesives: In industrial adhesives, the antioxidant properties of IPPD ensure the stability of the material under high temperature and high pressure environments. For example, after an industrial adhesive is treated with IPPD, its service life in a high temperature environment is increased by 25%.

Conveyor belt: In the manufacture of conveyor belts, IPPD significantly improves the wear resistance and tear resistance of conveyor belts. Data shows that the service life of conveyor belts containing IPPD is extended by 30% under heavy load conditions.

In summary, IPPD, as a highly effective antioxidant, effectively extends the service life of rubber products through its unique chemical properties, and demonstrates its important value in multiple industries. Whether it is automobile tires, industrial rubber or conveyor belts, IPPD can ensure its durability and stability in different environments.
