    Use of Antioxidant Masterbatch for Polymer Stabilization

    Non-yellowing Antioxidant Concentrates. Phenolic discoloration can result from many conditions, including overoxidation of hindered phenol antioxidants, pigment interaction (e.g. various grades of TiO) with phenols, ‘cardboard yellowing,’ and ‘gas fading’ due to the presence of NO gases (e.g. fork lift or gas heater fumes).

    Phenolic Antioxidant Research findings. Use of phenolic antioxidants, in spite of a large number of commercial products available, is quite limited in PVC.The major use is polymerization, but also some formulations used in medical applications may contain antioxidants. 308–310 Studies of Irganox 1076 and 1011 show that 30–40% antioxidant becomes inactive when a dose of 10 kGy is applied; when the

    PVC | Addivant

    Phenolic antioxidants such as LOWINOX® GP45 phenolic antioxidant stabilizer are often added as a chain stopper to terminate the reaction at the end of polymerization. These antioxidants carry the added benefit of helping prevent discoloration of the PVC powder during the drying process.

    Improving synthetic hindered phenol antioxidants: learning

    Many synthetic hindered phenol type antioxidants such as Irganox® 1010, 1330, 3114, 1076, 259, 1098 and 3125 rely on the BHT functionality for their antioxidant properties. The synthetic hindered phenols are made by joining BHT units together to increase the molecular weight and thus decrease the volatility and extractability of such antioxidants.

    percent in synthetic latex systems. They can be used synergistically with hindered phenolic antioxidants. synergy: mixtures of antidegradants The effective use of antidegradants is not linear. Generally, about three (3) phr is the maximum usage level for a single antioxidant or antiozonant in a rubber compound.

    Improving synthetic hindered phenol antioxidants: learning

    Most commercial synthetic hindered phenolic antioxidants are based upon 2, 6-di-tert-butyl-4-methyl-phenol (BHT). We compared the antioxidant e†ciency of BHT with that of 2, 6-di-tert-butyl-4-methoxyphenol (BHA) and found that BHA was 94% more e†cient. This implies that it may be advantageous to make new commercial hindered phenolic anti-

    For improved long term heat aging of these ABS blends, phosphite antioxidant can be replaced with the thioester LOWINOX® DLTDP antioxidant or the phenolic ANOX® 70 antioxidant. Antioxidants, typically in water dispersion form, are added in the latex before coagulation to protect ABS during drying & processing .

    Good-Rite® 3114 FFS antioxidant - Emerald Kalama Chemical

    Good-Rite® 3114 (Tris(3,5-di-tert-butyl-4-hydroxybenzyl)isocyanurate) is a high purity, non-yellowing, HMW, hindered phenolic antioxidant. It is extraction resistant, essentially non-volatile, and protects the polymer from degradation due to gas fading, heat, light, peroxides, and mechanical shear. 3114 provides superior long-term thermal stability and color stability; is effective in film

    Antioxidant effects during blade abrasion of natural rubber

    It was found that a representative alkyl/aryl paraphenylenediamine and hindered phenol antioxidant were only effective in reducing the rate of wear during smearing, when degradation processes are important. Furthermore, the reduction in wear rate during smearing was quite similar for these two antioxidants.
