The material selection process involves asking the right questions concerning the application and environment the part will be exposed to. Rubber compounds are all unique in their own way, and asking the right questions during the selection process enables us to match the right compound to the part. By understanding some of these considerations, you are better able to control the cost of your product while achieving the proper performance levels.
The hardness of rubber compounds is measured by the Shore A durometer; the higher the durometer number, the harder the compound. Softer compounds stretch easier and seal better on rough surfaces. Harder compounds offer greater abrasion resistance and resistance to extrusion.
