If a rubber or silicone product will come into contact with ozone gas during its lifespan, ozone exposure testing can help predict the material’s response. This makes ozone testing an important step of the quality assurance process. Understanding a rubber product’s ozone resistance helps ensure the safety and satisfaction of end users.

What’s the Purpose of Ozone Exposure Testing?

Ozone testing labs use ozone exposure test methods to determine a rubber or elastomer sample’s resistance to degradation. Ozone degradation occurs when traces of ozone in the air attack double bonds in rubber chains. This effect is most common in natural rubber, polybutadiene, styrene-butadiene rubber and nitrile rubber due to their double bonds. 

Accelerated ozone aging is useful for quality assurance testing, research and development, scientific research and odor removal. Submitting a sample to an ozone testing lab like ACE Laboratories helps determine a material’s vulnerability to degradation. This is useful for any rubber material that will likely be exposed to ozone gas in its applications.

How Does Ozone Exposure Testing Work?

Ozone tests for rubber are used to determine the effect ozone gas will have on a rubber or silicone material. So how do these tests work?

Rubber testing labs will use an ozone chamber with precise instrumentation to create an environment that mimics the material’s end use conditions, or by another testing specification or standard. Technicians then observe the material’s behavior under these conditions. This test method can also be used to estimate the lifespan of the material. 

If a material does not withstand the conditions in the ozone chamber, it will crack at the surface or break in two. If this happens, the rubber experts at ACE can assist with problem solving to make sure the material is ready to withstand ozone exposure and any other conditions.

Polymer & Rubber Testing

Ozone testing is a routine rubber test for polymer and rubber materials, especially in the automotive and transportation industries. It can reveal important information about rubber quality and how well a rubber material will perform for its end user. 

Ozone tests for rubber provide manufacturers with data they can use to predict their elastomer product’s performance over time, especially when used in conjunction with other rubber test methods, like abrasion testing, tear resistance and heat aging. Ozone testing is also useful for determining the quality of sourced rubber materials from a new distributor. 

Here at ACE, we provide rubber testing services for manufacturers across many industries, including:

  • Automotive
  • Aerospace
  • Construction
  • Industrial Goods
  • Tire

Manufacturers in industries that rely on meeting performance standards and industry benchmarks make ozone testing a regular part of their product development process.
