Minimum and maximum operational temperatures
Depending on the chemistry, thermoset polyurethanes can typically withstand a wide range of temperatures, unlike thermoplastics and rubber. From arctic tundras to dry, hot deserts, this customizable material can often maintain its original shape and physical properties even in the harshest conditions. However, there are a few conditions designers must consider while designing with thermoset polyurethane. In this post, we will discuss the importance of temperature range in your design and how it can potentially affect your product’s performance.
Operating temperatures typically refer to the range of temperature that a material can withstand, while successfully performing its role in an operation. In other words, it’s not just about surviving the temperature, but instead, executing a task in that temperature. As such, operating temperatures will be defined by the application’s environment, as well as the length of exposure to that environment. When making a material choice, it is very important to validate the physical properties that will not be compromised under the expected environmental conditions, during operation.
Dimensioning and tolerancing of your product can be very important with respect to temperature. Dimensions and tolerances need to account for the expansion caused by the anticipated temperatures of your application. Tight tolerances are not required for every project. Identifying the loosest acceptable tolerance is more accommodating to temperature variation, and can also reduce manufacturing cost. We will assist you with accounting for thermal expansion (or contraction) in your product’s design.
