    Application

    💡 YIHOO AO18 is a 100% phenol-free, eco-friendly dialkylphosphate ester antioxidant that is widely applicable to polyolefins, PVC, lubricating oils and other polymer systems.

    ✅ As an auxiliary stabilizer and mixed metal salt stabilizer for PVC materials, it effectively enhances initial color retention and anti-precipitation performance of the substrates.

    ✅ For unsaturated polyesters, this product can inhibit yellowing induced during resin synthesis, maintaining long-term color stability of the end products.

    ✅ Additionally, it serves as an extreme pressure anti-wear (EP-AW) agent in lubricating oils, significantly boosting the anti-wear performance of the formulated oils.
