Industrial Applications of 2,2'-METHYLENEBIS(4-ETHYL-6-TERT-BUTYLPHENOL)
| Industry | Application | Processing Method |
|---|---|---|
| Plastics Industry | Antioxidant for thermal stabilization and long-term thermo-oxidative stability of polyolefins (e.g., polyethylene, polypropylene) | Added by compounding with the resin during polymerization or prior to pelletization; typical dosage: 0.1–0.5 wt% |
| Rubber Industry | Antioxidant and antidegradant to retard oxidative aging of natural rubber and synthetic rubbers (e.g., SBR, BR) | Added during the mixing stage; compatible with vulcanization systems and commonly used synergistically with other phenolic or amine-based antioxidants |
| Lubricating Oils and Greases | High-temperature antioxidant additive to enhance the oxidation stability of base oils and complex lithium-based greases | Added in the final blending stage and homogenized via high-shear mixing; recommended dosage: 0.3–1.0 wt% |
| Adhesives and Sealants | Inhibits oxidative degradation during thermal processing and service life, maintaining bond strength and elasticity | Blended or dissolved with resins, plasticizers, and other components during adhesive formulation, either by solution mixing or melt compounding |
| Coatings and Inks | Secondary antioxidant component to prevent film yellowing and embrittlement after curing—particularly in outdoor weather-resistant coatings | Added during grinding or let-down; must be compatible with the resin system and non-migratory |
