Long term environmental stability
Figure 4 TOUGH-BLK 20 is engineered to give long term environmental UV and humidity stability. This means the material is tested for the ability to retain a high percent of the initial mechanical properties over a given period of time. This provides real design conditions to consider for the application or part.
Below is a sampling of the dataset. The full datasheet includes Indoor and Outdoor Stability data for Tensile Strength, Elongation at Break, Tensile Modulus and Impact Strength. Actual data value is on Y-axis, and data points are % of initial value.
Chemical and automotive fluid compatibility
The compatibility of a material with hydrocarbons and cleaning chemicals is critical to part application. Figure 4 TOUGH-BLK 20 parts were tested for sealed and surface contact compatibility per ASTM D543 test conditions and per USCAR2 test conditions. Tensile Strength (MPa) is shown below. The full datasheet includes additional data tables for Tensile Modulus, Elongation at Break and Notched Impact Strength.
