Abstract
A tray assembly includes a base tray, and an anti-slip pad disposed on the base tray, wherein the anti-slip pad has a friction coefficient in a range of about 0.5 to about 20 based on ASTM D1894, and a surface resistance in a range of about 10{circumflex over ( )}6 Ω/cm2 to about 10{circumflex over ( )}9 Ω/cm2 based on ASTM D257, and the anti-slip pad includes at least one of a thermoplastic olefinic elastomer (TPO), natural rubber, styrene-butadiene rubber (SBR), and polypropylene (PP).
Claims7
An anti-slip pad comprising:
- a base layer;
- a first non-slip layer disposed on a first surface of the base layer;

- and
- an antistatic layer disposed on the first non-slip layer, wherein
- the first non-slip layer and the second non-slip layer include at least one of a thermoplastic olefinic elastomer (TPO), natural rubber, styrene-butadiene rubber (SBR), and polypropylene (PP), and
- the antistatic layer comprises thermosetting resin and an antistatic agent.
