New to these terms?What the numbers mean
- 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.
- V-0
- UL 94 V-0: if it catches fire, the flame stops within 10 seconds, with no burning drips.
- Specific gravity
- How heavy it is compared with water. 1.2 means 20 % heavier than the same volume of water.
- kg/cm²
- Pressure. 1 kg/cm² is roughly the pressure of the air around us; minus figures are vacuum.

Try it
Two quick, hands-on ways to understand this product before you ask.
How firm is 20–30 Shore A?
Drag the press down onto a block, then let go. It gives way and springs back as the real rubber would: soft like a rubber band.
Will it take your temperature?
Drag the marker to the hottest (or coldest) your part sees.
