Desco 66466 Statfree T2 Plus Dissipative Dual Layer Rubber Tray Liner, Gray, 16" x 24" x .060"
Desco 66466 — Statfree T2 Plus Dissipative Dual Layer Rubber Tray Liner, Gray, 16" × 24" × .060"
The Desco 66466 Statfree T2 Plus Tray Liner is a precision-cut ESD worksurface liner designed for component trays, parts bins, and shallow handling fixtures. The 16" × 24" format with .750" radius corners fits standard tray dimensions without bunching or lifting at corners. The two-layer construction delivers a dissipative top surface for safe contact with ESD-sensitive devices and a conductive bottom layer for grounding and ESD monitor compatibility. Both layers carry a Limited Lifetime Warranty. Meets ANSI/ESD S20.20 worksurface requirements. Made in the USA.

Key Features
- Radius Corner Cut (.750 in): Pre-cut radius corners fit standard component trays and parts bins cleanly without bunching, lifting, or folding at corners.
- Limited Lifetime Warranty: Both the dissipative top layer and conductive bottom layer are covered by Desco's Limited Lifetime Warranty.
- Dissipative Top Layer: Meets ANSI/ESD S20.20 worksurface required limits and ANSI/ESD S4.1 recommendations. Does not generate static charge; controls discharge rate from ESD-sensitive devices placed in the tray.
- Conductive Bottom Layer: Low-resistance path to ground enables use with ESD workstation continuous monitors and reduces Rtg from top surface to grounding point.
- Nitrile Rubber Oil-Resistant Compound: Resists oil absorption, maintaining electrical and physical properties through service life. Suitable for solder workstations with flux and chemicals.
- UV Stabilizer Additives: Preserves color retention and ESD performance; prevents surface cracking and deterioration over time.
- Laser Engraved Identification: ESD protective symbol, specifications, and manufacturer information on the bottom layer for product identification and EPA auditing.
- RoHS Compliant. Made in USA.
Frequently Asked Questions
What is the difference between a tray liner and a mat kit?
A tray liner like the 66466 is a precision-cut liner sized to fit inside component trays, parts bins, or handling fixtures. It has radius corners so it lays flat without bunching. A mat kit is a larger flat mat with grounding hardware for covering an entire bench worksurface. Tray liners still require grounding — they ground through the tray or fixture they rest in, which must be connected to a common point ground.
Does the Desco 66466 tray liner need to be grounded?
Yes. Like all ESD worksurfaces, the tray liner must be properly grounded to dissipate ESD charges. It grounds through the conductive bottom layer via contact with the tray or fixture, which should be connected to a common point ground at the workstation.
Is the T2 Plus tray liner compatible with flux and soldering chemicals?
Yes. The nitrile rubber oil-resistant compound resists absorption of flux, solvents, and other common soldering chemicals, maintaining ESD performance and physical integrity through service life.
