Polymers & Rubbers Testing


Ash content:

This test helps in determining the amount of fillers in a specimen after the polymer has been burned off and suitable for the determination of the ash content of rubber compounding materials. The test methods may be used for quality control, product acceptance, or research and development.
Test Method: ASTM D2584, D5630, ISO 3451

Bulk density:

This test helps in determining the weight per unit volume of material. The bulk density (morphology) of the rubber contributes significantly to the binder’s performance and is used as a property in the specification of the rubber.  This test method provides a measure of the crumb rubber’s bulk density.
Test Method: ASTM D1895B

Compression set under constant deflection:

This test helps in determining the ability of elastomeric material to maintain elastic properties after prolonged compressive stress. The set test is used to determine the quality of rubber compounds and their applicability to certain types of usage.
Test Method: ASTM D395 B
