Ozone is one of the strongest oxidants and can oxidize most organic matter, including elastomers, seriously affecting its life and quality. Ozone is produced by many factors: UV exposure, discharge processes, air pollution (NOx), etc. The overall ozone concentration in nature is obviously increasing.

At present, p-phenylenediamine is widely used because of its superior anti-ozone effect and low cost. However, p-phenylenediamine can also cause significant discoloration and contact contamination of vulcanizates, so it cannot be used well for white or colored rubber products, such as white, light-colored soles, medical gloves, latex pillows, etc.

In order to solve the shortage of traditional antiozonants, our company specially developed the non-polluting antiozonant YLSCH-RBB® NOXCA, which provides a certain guarantee for the development of colored rubber products.

YLSCH-RBB® NOXCA (3,9-dicyclohex-3-enyl-2,4,8,10-tetraoxaspiro[5.5]undecane) Appearance is pale yellow to brownish yellow flakes, slightly aromatic taste.SYNONYM: Lanxess Vulkazon AFS/LG. The product is a cyclic unsaturated acetal that does not contain active hydrogen atoms (aryl-NH, -OH, -SH) in structure, and is an acetal containing olefinic double bonds. In the process of molecular chain oxidation, it is not used as a chain terminator, but the double bond of the antiozonant molecular chain and the double bond of the polymer molecular chain have a competitive reaction with ozone.

Applications:

1. Non-polluting antiozonant, good material flow and excellent anti-aging performance. Excellent color retention and processability during vulcanization, especially for light-colored and colored rubber products, without changing the color of the finished product.
2. When used alone for CR, CIIR, BIIR, the anti-ozone performance is very good, and there is no need to use protective wax together.
3. It is also suitable for the protection of inner tube compounds such as tires with combined use of NR and SBR and IIR/CR (combination ratio of 95/5).
4. The product itself has no anti-oxidative thermal aging, bending and anti-rubber poisoning effects. It needs to be used with other antioxidants to prevent the attack of oxygen under dynamic or static conditions.
5. Because of its non-polluting properties, it is specially suitable for the manufacture of light-colored, colorful and non-contact pollution products, especially high-end rubber products. like

① Rubber strips, hoses, seals, cables, auto parts;

② Butyl inner tubes, power tires, white sidewalls, colored tires, sports car tires, off-road tires;

③ Sports shoes and other leisure products;

④ Latex products, such as latex pillows, latex mattresses, medical bandages, etc.
