Jan 1, 1995 · Ozone cracking in elastomers can be characterised by two parameters: a threshold condition and a characteristic rate of growth. Many chemical additives can reduce the growth rate but …

Antioxidants – are chemicals that are used to protect rubber articles against attack from oxygen (O2). Antiozonants – are chemicals and / or waxes that “bleed” to the surface of a rubber article, to protect …

An antiozonant, also known as anti-ozonant, is an organic compound that prevents or retards damage caused by ozone. The most important antiozonants are those which prevent degradation of …

The document examines different types of antiozonants, including p-phenylenediamines, and how they work to protect rubber from ozone through scavenging or forming a protective film.

Antiozonant refers to a substance that is added to rubber to prevent the harmful effects of ozone on its surface. It works by scavenging the ozone present on the surface of the rubber before it can react …

Nov 11, 2018 · At present, the best antiozonant molecules used in the industrial practice are N,N’-substituted p-phenylenediamines (PPDs). In this review, the reaction of ozone with diene rubber …
