Irganox® 1010 is a highly effective antioxidant offered by BASF. Here is the English introduction of this product:

Function and purpose: It is a highly effective, non-discoloring, sterically hindered primary phenolic antioxidant stabilizer that protects organic substrates against thermo-oxidative degradation.

Product highlights:

Good compatibility: It shows good compatibility with a wide range of polymers and substrates, which enables it to be well incorporated into different materials.

High resistance to extraction: It has a high resistance to extraction, ensuring its long-term stability and effectiveness within the material.

Low volatility: The product has low volatility, which means it is not easily lost during processing or use, providing stable protection.

Odorless: It is odorless, which is beneficial for applications where odor control is important.

Can be used in combination with other additives: It can be used in combination with other additives such as co-stabilizers (thioethers, phosphites, phosphonites), light stabilizers, and other functional stabilizers to achieve better performance.

Manufactured using a tin-free process: This manufacturing process is environmentally friendly and does not involve the use of tin, which is an important consideration for some applications.

Suggested applications: It is widely used in polyolefins such as polyethylene, polypropylene, and polybutene, as well as in olefin copolymers such as ethylene vinyl acetate copolymers. It is also recommended for the processing of polymers such as polyacetals, polyamides, polyurethanes, polyesters, PVC, styrene homo- and co-polymers, ABS, elastomers (including butyl rubber, SBS, SEBS, EPM, and EPDM), adhesives, natural and synthetic tackifier resins, and other organic substrates.

Physical and chemical properties: The chemical name of Irganox® 1010 is pentaerythritol tetrakis(β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate). It appears as a white to slightly yellow crystalline powder. The molecular weight is 1178. It has a melting point in the range of 110°C to 125°C, and the flash point is 297°C. The solubility in different solvents at 20°C is as follows: acetone (47%), benzene (56%), chloroform (71%), ethyl acetate (46%), hexane (0.3%), and methanol (1%).
