Glove thickness is usually given in mil. One mil is one thousandth of an inch, about 0.025 mm. BestSky cleanroom nitrile gloves are 4.0 mil.
A glove is not the same thickness all over
The stated thickness is a nominal figure. A dipped glove is thinnest at the cuff and thickest at the fingertips, where the wear is. These are the figures from our Technical Data Sheet:
| Where | Thickness | Tolerance |
|---|---|---|
| Cuff | 0.060 mm | ± 0.015 mm |
| Palm | 0.070 mm | ± 0.015 mm |
| Finger | 0.100 mm | ± 0.015 mm |
What 4.0 mil is good for
- Touch sensitivity – thin enough to handle small components, tweezers and wafers with control.
- Comfort – a light glove is less tiring over a shift. Size M weighs about 4.8 g.
- Frequent changes – cleanroom procedures call for regular glove changes, so a light glove is the practical choice.
Strength
Thin does not mean weak. Our data sheet specifies a force at break of at least 7 N and elongation of at least 500 %, both before and after aging.
Sizes
| Size | Palm width | Length | Weight |
|---|---|---|---|
| S | 85 mm | 305 mm | 4.4 g |
| M | 95 mm | 305 mm | 4.8 g |
| L | 105 mm | 305 mm | 5.2 g |
If you are unsure of the fit, ask for samples in two sizes and let the operators who will wear them decide.
