Understanding Ozone Testing: Why It’s Crucial for Material Durability

To ensure optimal product performance, ozone testing plays a crucial role in assessing material durability against ozone-induced damage. Understanding how ozone exposure affects materials, especially rubber and elastomers, is essential for industries that rely on these products for high performance and longevity.

What is Ozone and How Does It Impact Product Life?

Ozone is a reactive gas made up of three oxygen atoms and is commonly present in the Earth’s atmosphere. While its presence in the upper atmosphere is useful for blocking harmful UV radiation, ground-level ozone can be detrimental to materials like rubber and elastomers.

Thus it is important to understand that for industries reliant on rubber and polymer-based products, mitigating ozone’s effects is essential for maintaining product reliability and customer satisfaction. Automotive, aerospace and defense, construction, medical devices, and consumer industries are some of the major users of rubber products and have to rely on ozone stimulation to ensure a good quality product.

When exposed to ozone, materials undergo a chemical reaction that can cause cracking, and weakening of the material, reducing its elasticity and strength and thus leading to reduced life span. It is therefore important to assess a material’s resistance to ozone-induced damage. The ozone resistance test simulates real-world exposure by subjecting samples to specific ozone concentrations, temperatures, and durations. This allows manufacturers to evaluate the cracking behavior and durability.

We at Krishna Metallurgical Laboratories are among the very few laboratories in India that possess world-class test equipment for ozone aging and stimulation. Our topline chamber imported from Toyoseiki Japan is one of the most advanced and reliable chambers that can give you both dynamic as well as static testing.  While dynamic testing simulates real-world conditions by testing materials under motion and tension, ideal for automotive and industrial applications, static testing provides detailed insights into long-term material performance under constant ozone exposure.
