New to these terms?What the numbers mean
- Shore A
- How hard the rubber is. 25 is soft like a rubber band, 40 like a pencil eraser, 70 like a car tyre, 80 firm like a shoe heel.
- Tensile
- How hard you can pull before it breaks. Higher is stronger.
- Elongation
- How far it stretches before breaking, as a %. 400 % means four times its own length.
- Compression set
- How much thickness it fails to recover after being squeezed. Lower is better for seals.
- Tear
- How well it stops a small cut from spreading.

Try it
Two quick, hands-on ways to understand this product before you ask.
How firm is 40–80 Shore A?
Drag the press down onto a block, then let go. It gives way and springs back as the real rubber would: from a pencil eraser to firm like a shoe heel.
Will it take your temperature?
Drag the marker to the hottest (or coldest) your part sees.
