The rubber tree is the main source of natural rubber, which is used in the manufacture of various products with the tire industry being its most popular use. The rubber tree is cultivated in several regions of the world, and Southeast Asian countries are the greatest natural rubber producers.
Global Rubber Antioxidant Market Professional Research
Rubber antioxidant is an additive added in the production process to prevent rubber aging. The common rubber antioxidant is aromatic amine, which is mainly used in tire, belt, hose, cable, etc. According to the application types, rubber antioxidants can be mainly used in tires and automotive rubber products.
Antioxidants are used in many applications, and the chemistry of these materials has been reviewed 〈92KO(3)424〉.For example, the degradation of polymers may be inhibited by the addition of antioxidants, and the most important chain transfer antioxidants are phenols and aromatic amines 〈B-79MI 506-05, 80PAC365〉.Two quinoline derivatives are used as
Antiozonant Article about antiozonant by The Free Dictionary
It primarily includes antioxidants and antiozonants. Antioxidants are used to protect rubber from deterring the effect of oxygen during its shelf life, whereas antiozonants are chemicals/waxes that 'bleed' to the surface of rubber articles, protecting them from ozone attack.
To the three vulcanized rubber composites were added 13 wt% of EVA, as a swelling agent and tension distributor, and processing antioxidants (1 phr) Irganox 1010 ® and Irgafos 168 ® (3:1), before the feed. 2.3. Characterization

Mar 02, 2017· The radiation treatment was applied to unstabilized material formulation and to the blends previously modified with 0.5 phr antioxidant (Igranox 1010, Ciba Geigy ®). Characterization Chemiluminescence (CL) determinations were carried out by nonisothermal measurements over the temperature range 30–250 °C at heating rate of 5 °C min −1 .

Examples of amine antioxidants are AKROCHEM ® A.O. S and PANA. Certain amines and amine derivatives were the first chemical antidegradants to be used in rubber and are still some of the most common types of antidegradants used by the rubber industry. Amines offer heat resistance, anti-flex cracking properties and neutralize heavy metal poisoning.
For protection of elastomeric materials against ageing, antioxidants such as UV-stabilizers and antiozonants are used. Although historically N-phenyl-N'-(1,3-dimethylbutyl)-p-phenylenediamine (6PPD) was the only approved antiozonant in Germany, a range of other phenylene diamine antiozonants (excluding 6PPD) are permitted for use in rubber articles intended for repeat
