Depending on the polymer type (plastic, rubber, ...) you can use the following testers:

· Brinell hardness

· Bloom

· Knoop hardness

· Leeb rebound hardness

· Rockwell hardness

· Vickers hardness

Shore durometers work well too. They offer a good range.

Shore is typically used for polymers.

Brinell, Vickers, Rockwell and Knoop tests are mainly performed on metals.

Tank you very much

You can use shore durometers. They work well and are affordable.

Dear Abdalla

You can use vickers microhardness test

it is a common test for polymer hardness measurement

shore durometers are typically used for this purpose. here is an example in the following link;

by using an Instron Universal Testing Machine (Model 5569),

The Rockwell hardness tester is generally used for polymers hardness testing.

Hardness tester

For RUBBER shore A, IRHD

FOR PLASTIC SHORE D

for what types of polymers? Rubbers or plastics?

Shore A = Rubbers

Shore D= plastics
