A Digital Durometer Shore C (0-100HC) is a precision instrument used to measure the hardness of soft to medium-hard materials, particularly rubber, elastomers, gels, foams, and soft plastics. Here’s a breakdown of what each term means:
🔍 Key Features of the Durometer Shore C
| Feature | Description |
|---|---|
| Digital | Displays hardness values on an LCD screen—more accurate and easier to read than analog models. |
| Shore C | A specific Shore scale (per ASTM D2240) is used for softer materials than Shore A. |
| 0-100HC | Indicates the hardness range: 0 (very soft) to 100 (firmest measurable on Shore C scale). |
🧪 Common Applications of Durometer Shore C
Shore C is ideal for materials too soft for Shore D, but too firm for Shore A, such as:
- Soft rubber rollers
- Flexible foams
- Cellular plastics
- Elastomer blends
- Vinyls and flexible thermoplastics
📐 How It Works
- The durometer indenter (a conical point under specified force) presses into the material.
- The digital readout shows the resistance level as a number from 0 to 100.
- Higher numbers = harder material.
