Global Antiozonants Market: Introduction

  • Antiozonants have the ability to avert or reverse oxidation caused due to ozone. Ozone reacts with rubber and deteriorates rubber or other forms of elastomers. Antiozonants act as additives that protect elastomers from fatigue caused due to exposure to atmospheric ozone.
  • Elastomeric materials tend to become brittle and develop cracks with consistent exposure to ozone. Antiozonants are likely to witness notable demand in the near future, due to their ability to overcome damage caused by ozone.
  • Antiozonants are applied only on the surface of the rubber for its protection from ozone cracking, as ozone attacks primarily occur at the surface of the rubber

Key Drivers of Global Antiozonants Market

  • Rubber is used to manufacture a variety of products including tires, mats, belts, hoses, and gloves. Demand for tires with increased resistance to ozone, heat, and mechanical stress is likely to drive the demand for antiozonants between 2019 and 2027.
  • Ozone gas can occur naturally or it can generate during electric discharge caused by sparking or corona discharge. Ozone is produced due to the action of sunlight on volatile organic compounds (VOCs), such as gasoline vapor, present in the air. Rise in the demand for ozone-resistant rubbers, which have been pre-treated to inhibit ozone cracking, is anticipated to augment the global antiozonants market during the forecast period.
  • Machines such as compressors, which consist of moving parts made of rubber and serve the purpose of insulating the material, may hold the static electricity buildup within them, which poses a risk of ozone cracking to them
  • Antiozonants belong to the anti-degradants class of rubber-processing chemicals. Antiozonants is projected to be the key segment of the global rubber processing chemicals industry between 2019 and 2027.
  • The global antiozonants market is monitored by a stringent regulatory framework. Antiozonants should essentially be economical and they should have lower or no toxicity. Several regulatory bodies, including the Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) and National Emission Standards for Hazardous Air Pollutants (NESHAP), monitor the market.

Anti-ozone Waxes and PPD Derivatives to be Key Product Segments

  • Based on product, the global antiozonants market can be divided into anti-ozone waxes, paraphenylene diamine (PPD) derivatives, ethylene diurea (EDU), and others
  • The anti-ozone waxes segment is anticipated to hold a major market share during the forecast period. Anti-ozone waxes serve as low-cost antiozonants. Wax is capable to flow to the surface of the rubber and form a protective layer on it. Regular chemical antiozonants usually comprise microcrystalline wax or the blend of paraffin and microcrystalline waxes.
  • Paraphenylene diamines (PPDs) work as primary antioxidants and they are regarded as the most powerful variant of chemical antiozonants. The PPD derivatives prevalent in used include PPD Type I (N, N’-dialkyl-p-phenylenediamine), PPD Type II (N-alkyl-N’-aryl-p-phenylenediamine), and PPD Type III (N, N’-diaryl-p-phenylenediamine).
  • PPDs are effective antiozonants found in natural rubber and polyisoprene, as they are only moderately soluble in these rubbers and they can migrate to the rubber surface to provide good ozone protection. PPDs are extensively used in belts, tires, and extruded and molded rubber products including antiozonants and anti-flex cracking agents. However, owing to their characteristics such as staining and discoloring, PPDs are not preferred in white or colored products.
  • Manufacturers are engaged in developing highly efficient product variants to meet the surging demand for antiozonants. For instance, the FLEXZONE 4L antiozonant offered by SI Group, Inc. provides exceptional initial static protection; protects rubber from oxygen degradation; offers anti-flex cracking protection; and features lower discoloration than PPD.

Significant Growth Potential for Use in Tire as well as Non-tire Applications

  • Based on application, the global antiozonants market can be divided into: tire and non-tire
  • Oxidation or ozonation of rubber can be slowed down considerably with the addition of antiozonants. These are chemicals that scavenge and neutralize the ‘oxy’ radicals before they auto-catalyze the polymer.
  • Antiozonants are expected to witness rising demand in the automotive industry for use in tire applications in the next few years. The prevailing issue of ozone cracking in sidewalls of automobile tires can be prevented by adding antiozonants to the rubber before vulcanization.
