When testing soft materials such as rubber, elastomers, plastics, and polymers, conventional hardness methods like Rockwell or Brinell are not suitable. Instead, a durometer hardness tester is used.
Durometer measures the resistance of a material to indentation using a calibrated spring force and a standardized indenter. The depth of indentation is then converted into a Shore hardness value ranging from 0 to 100.
Different Shore scales are used depending on material stiffness:
🔹 Shore A – Commonly used for soft rubber, elastomers, and flexible plastics
🔹 Shore B – For slightly harder rubber and semi-rigid materials
🔹 Shore D – Used for harder plastics and rigid polymers
During testing, the indenter is pressed onto the material surface with a controlled force, and the hardness value is obtained based on how much the indenter penetrates the material.
📊 Why Durometer Testing Matters
• Ensures product consistency
• Verifies material specification
• Evaluates flexibility and durability
• Supports quality control in manufacturing
Durometer hardness testing is widely applied in industries such as automotive, polymer manufacturing, rubber production, and product quality assurance.
At Obsnap Testing, we now have a new master durometer (Shore A, B & D) available for hardness testing of soft materials, supporting accurate measurement and material verification.
