Purus International PS 2436 38 W EnviroTack Adhesive Mat, 24x36, 30-Layer, White, Case of 4

The Purus EnviroTack PS 2436 38 W is a 24" x 36" white cleanroom sticky mat designed to capture and contain dirt, dust, and particulate from foot traffic and wheeled equipment at controlled environment entryways. The 24x36 size is one of the most widely used footprints in cleanroom and controlled environment applications, fitting standard single-door entries and gowning room access points. Each mat features 30 peel-away adhesive layers of low-density polyethylene film with a regular-tack acrylic adhesive coating and a numbered tab for single-layer removal. Made with Purus's plant-based Cardia BioHybrid material and recyclable in conventional plastic streams.

Sold in cases of 4 mats.

Frequently Asked Questions

What is the difference between the PS 2436 38 W and the PS 2436 38 G-HT?
Both are 24" x 36" mats with 30 layers, but the PS 2436 38 W is white with regular tack (6.5 oz peel adhesion) in a case of 4, while the PS 2436 38 G-HT is grey with high tack (9.25 oz peel adhesion) in a case of 8. Choose the W for standard foot traffic applications; choose the G-HT for heavy wheeled equipment, high-traffic environments, or where maximum particle capture is required.

Why is 24x36 one of the most common cleanroom mat sizes?
The 24" x 36" footprint fits most standard single-door entries and provides enough surface area to ensure both feet contact the adhesive with each step. It’s also a practical size for gowning room benches and secondary contamination control checkpoints. For wider entries or double doors, the 36" x 45" size is recommended.

How do I know when to peel a layer?
Peel when the top layer is visibly soiled, or on a scheduled interval per your contamination control SOP. The numbered tab on the mat edge shows how many layers remain so you can plan reorders before running out. Most facilities follow a time-based or traffic-count schedule rather than relying solely on visual inspection.

What makes Purus EnviroTack mats more sustainable than standard sticky mats?
Purus mats incorporate Cardia BioHybrid material — a GMO-free, renewable, plant-based additive that reduces CO₂ emissions compared to conventional LDPE mats. They are also recyclable in standard plastic recycling streams, unlike most sticky mats which go to landfill after use.
