- What is styrenated phenol used for?
- Styrenated Phenol is a very widely used and inexpensive non-staining, non discoloring antioxidant for white / colored or transparent rubber products Styrenated Phenol also finds applications as a stabilizer for synthetic rubbers and plastics such as Polypropylene, Polyethylene, high impact polystyrene, adhesives, oils and plasticizers.
- What are phenolic antioxidant products?
- Typical phenolic antioxidant products include 2,2′-methylenebis (6-tert-butyl-4-methyl-phenol) (antioxidant 2246), 2,6-di-tert-butyl-4-methylphenol (BHT (264)), and styrenated phenol (antioxidant SP). Among them, antioxidant 2246 has a good performance to protect rubber from aging caused by heat, oxygen, and metals.
- Why do we need antioxidants for rubber composites?
- Therefore, for a real application, the antioxidants are indispensable to retard the thermal-oxidative-aging process of the rubber composites and then prolong the service life. In this review, we systematically review the recent progress of antioxidants for rubber.
- Does styrenated phenol affect rubber vulcanizates?
- Styrenated Phenol disperses very easily in dry rubber compounds and does not bloom or affect the color, odor & transparency of the rubber product. It does not influence the viscosity, scorch and cure characteristics of rubber compounds nor does it have any influence on unaged mechanical properties of rubber vulcanizates.
- What are the TPS of rubber antioxidants?
- The TPs of rubber antioxidants have been observed in some studies under environmental conditions. As one of the widespread rubber antioxidants, amine antioxidants (PPDs: TMPPD, DPPD, 6PPD, and 6PPDTZ) could react with O 3 (in parts per billion volume levels) in the environment and produce PPD-quinone .
- What are the benefits of phenol reaction products with dicyclopentadiene & isobutene (CPL)?
- Furthermore, the addition of phenol, 4-methyl-, reaction products with dicyclopentadiene and isobutene (CPL) as an antioxidant improves heat resistance and oxygen tolerance.
