Note #1: The information provided above is for reference purposes only. It is intended to be utilized as a “guide” when comparing the typical physical properties of different materials. Aero recommends that the buyer perform any tests required to determine the performance characteristics and suitability of a particular material for a specific application and elastomer selection.
Note #2: A rubber compound can be a blend of two or more elastomers (when compatible) in order to influence the finished part’s function and service life as well as competitive pricing.
Note #3: “Typical Temperature Range” is unrelated to any particular use or application. It is a general guideline to compare with other elastomers. Field tests of part samples by the user and ASTM lab tests of compound slabs are necessary to determine functional acceptability and service life.
Note#4: Latex Free vs Non Latex – The FDA recommends using the term Non Latex. “The reason for this recommendation is that the agency is not aware of any tests that can show a product contains no natural rubber latex proteins that can cause allergic reactions. Without a way to verify that a product is completely free of these proteins, a claim that it is “latex free” is scientifically inaccurate and may be misleading.” Read More
