Properties of Rubber

Various type of polymer can be used as reference to make rubber molding. Involvement of technical division together with designer and product engineer to evaluate all aspects of product service requirement and give the efficient cost compound will optimize the production result based on the requirements.

Below table is only used as general guide to choose the appropriate elastomer. Santo Rubber will not give any warranty for the accuracy of data and therefore we will not responsible for the usage of this table.

Many factors must be considered before choosing of elastomer compound for the certain usage. Because of compound variation and various consequences which could be happened as results of temperature changing, durability, and equipment condition, customers should do the test and define the right elastomeric for the application needed.
