A mid-tear strength, production-grade rubber combined with Shore 65A hardness and a high elongation at break

Figure 4 RUBBER-65A BLK delivers on the promise of additive manufacturing with true direct digital production of rubber plastic parts. It is a high precision resin producing parts with a smooth surface finish. A mid-tear strength material for the production of medium hard rubber parts with slow rebound, for applications such as grips, handles, gaskets, bumpers, seals, vibration dampening components and more.

Long term environmental stability

Figure 4 RUBBER 65A BLK 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.
The chart shows 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 RUBBER 65A BLK 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.
