How to judge the quality of the anti-static table mat
1. Look: Open the package, the surface color is even, no bubbles, spots and other phenomena.
2. Smell: This product is a brand-new rubber production with a slight rubber smell. Our factory has improved the formula, and the smell is absolutely the smallest among the same products.
3. Tear: anti-static table pad The green surface anti-static layer and the black surface conductive layer are made by vulcanization bonding. You can tear the green and black sides by hand. If the green side is torn with black glue, it means that the bonding of this product is qualified. (The degree of adhesion directly affects the elimination of static electricity).
4. Pull: Pull the anti-static table mat, the green surface always stays green, and the color does not turn white and does not change color. This product is a new rubber material. You can also use your hands (the green side does not change color, and the black side does not break).
5. Test: Use a surface resistance tester. The green surface resistance is 10-9th power of 10 ohms, and the black surface resistance is 10-5th power of ohms. The antistatic index of this range is up to standard.
