Factors Affecting Chemical Resistance

While POM is renowned for its exceptional chemical resistance, it is crucial to understand the various factors that can affect its ability to withstand different chemicals. By considering these factors, you can ensure optimal performance and longevity in your POM applications.

Concentration

The concentration of chemicals can significantly impact the chemical resistance of POM. Higher concentrations can lead to increased chemical attack, potentially compromising the material’s integrity. Therefore, it is important to consider the specific concentration levels that POM will be exposed to and select the appropriate grade accordingly.

Temperature

Elevated temperatures can affect the chemical resistance of POM. Higher temperatures can accelerate chemical reactions, leading to increased degradation of the material. When selecting POM for applications with high-temperature exposure, it is crucial to consider the material’s temperature limitations and choose a grade that can withstand the anticipated temperatures.

Exposure Time

The duration of exposure to chemicals can also impact the chemical resistance of POM. Prolonged exposure can result in gradual degradation of the material, leading to reduced performance over time. It is essential to consider the expected exposure time and select a POM grade that can provide the necessary chemical resistance for the intended duration.

Mechanical Stress

Mechanical stress can affect the chemical resistance of POM. Aggressive mechanical conditions, such as high pressure or abrasive environments, can weaken the material’s structure and make it more susceptible to chemical attack. When selecting POM for applications with significant mechanical stress, it is important to choose a grade that can withstand these conditions without compromising its chemical resistance properties.

Surface Finish

The surface finish of POM can also influence its chemical resistance. A rough or porous surface can provide more opportunities for chemicals to penetrate and attack the material, compromising its integrity. It is advisable to select POM grades with a smooth surface finish to enhance its resistance to chemicals.

By considering these factors, you can make informed decisions when selecting POM for your applications to ensure optimal chemical resistance. Always consult specific chemical compatibility data and take into account the operating conditions to achieve the best performance.
