The Japanese ADK-hindered phenolic antioxidant AO-20 from Adeka is suitable for polypropylene ABS

Chemical type and characteristics: 

AO-20 is a hindered phenolic antioxidant (primary antioxidant), which inhibits the oxidative degradation of plastics by capturing free radicals. Its key features include: low volatility, ensuring long-term stability;

good hydrolysis resistance, suitable for humid environments;

excellent compatibility, easy dispersion in polymer matrices; 

effective inhibition of yellowing and discoloration, especially suitable for white or light-colored products

Main applications: 

Applicable materials: Widely used in olefin polymers such as polypropylene (PP), polyethylene (PE), and ABS engineering plastics, and also in nylon systems (such as white nylon).

 Core application:

As a primary antioxidant, it provides antioxidant protection during long-term storage and use (such as anti-aging and anti-cracking).

 In nylon applications, it is used in combination with 1010 or 1098 to enhance temperature resistance and color stability。

 It is suitable for scenarios requiring high purity, such as food packaging

Performance advantages:

 Compared with traditional antioxidants (such as 1010), AO-20 has a lower tendency to discolor, making it particularly suitable for color-sensitive applications (such as white nylon).

In flame-retardant formulations, it can synergically enhance the thermal stability of materials. High efficiency:

A small amount of addition can significantly extend the lifespan of plastic products.

Usage suggestion:

It is usually compounded with other antioxidants (such as phosphite esters or thioesters) to produce a synergistic effect.

The addition amount is generally 0.1-0.5%, and the specific amount needs to be adjusted according to the resin type and processing conditions.

 When storing, it should be sealed and moisture-proof, and avoid high-temperature environments。
