Frequently Asked Questions
A rubber raw material testing lab evaluates properties such as plasticity, viscosity, hardness, tensile strength, elongation, ash, moisture, abrasion, and thermal stability to verify material quality, consistency, and suitability before production.
Natural rubber testing commonly focuses on plasticity, viscosity, ash, dirt, and volatile matter, while synthetic rubber testing evaluates grades such as SBR, NBR, EPDM, and CR for consistency, physical properties, and application requirements.
Curing behaviour determines how a rubber compound responds during vulcanization and moulding. Testing helps assess scorch time, cure time, and curing characteristics, reducing the risk of under-cured or over-cured parts and inconsistent product performance.
